Supports up to five (5) HTTP and HTTP Secure (HTTPS) sessions. Firmware Update Provides notification of the latest firmware with the ability to schedule update at a preferred time through Instant On mobile app and cloud-based web portal. Default DHCP Client Mode Allows the switch to be directly connected to a network, enabling plug-and-play operation. In the absence of a DHCP server on the network, the switch falls back to the static address 192.168.1.1. Port Mirroring Enables traffic on a port or VLAN to be simultaneously sent to a network analyzer for monitoring. Event Logging and Alerts Provides detailed information for problem identification and resolution. Account Management Allows administrators to add, modify, delete and transfer management accounts and passwords for secure access to Instant cloud management solution. Locator LED Allows users to set the locator LED on a specific switch to either turn on, blink, or turn off; simplifies troubleshooting by making it easy to locate a particular switch within a rack of similar switches. Schedule Configuration Global Schedule feature can be applied to time-based ACLs, port or interface shutdown, or PoE power delivery; up to 3 schedules can be configured. PoE scheduling allows user to configure a specific day/time of the week (e.g. business hours) for Instant On switches to supply power to connected devices (e.g. surveillance cameras, access points etc.). Quality of Service (QoS) Traffic Prioritization Provides time-sensitive packets (like VoIP and video) with priority over other traffic based on DSCP or IEEE 802.1p classification. IEEE 802.1p/Q VLAN Tagging Delivers data to devices based on the priority and type of traffic; supports IEEE 802.1Q. Class of Service (CoS) Sets the IEEE 802.1p/DSCP priority to queue mapping (4 queues). Supports strict priority queuing (SP) or weighted round robin (WRR) queuing. SP and WRR queuing can be configured on individual switch ports. Advanced Classifier Based QoS Classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information. Access Switching SFP/SFP+ Fiber Connectivity Provides fiber connections for uplinks and other connections across longer distances than copper cabling can support. SFP ports are in addition to available copper Ethernet ports, providing a higher total number of available ports. Two (2) SFP 1G ports available on 8-port models and four (4) SFP+ 1G/10G ports on 24-/48 port models. Ethernet Alliance Certified Class 4 PoE (IEEE 802.3at) Provides up to 30 W per port, which allows support of the class 4 PoE capable devices such as video IP phones, wireless access points, and advanced pan/tilt/zoom security cameras, as well as any 15.4 W IEEE 802.3af-compliant end device; mitigates the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments. Auto-PoE Power Configuration The switch automatically assigns the required power to a port for a PD device based on Link Layer Discovery Protocol (LLDP). PoE Power Allocation Support multiple methods (LLDP-MED automatic, class of PoE, or usage-based) to allocate PoE power for more efficient energy savings. Auto MDI/MDI-X Adjusts automatically for straight-through or crossover cables on all 10/100/1000 ports. Network Security TPM-Based Security Includes a Trusted Platform Module (TPM) for secure hardware- based generation and storage of cryptographic keys used for secure connection to the Instant On cloud portal. IEEE 802.1Q VLAN Support Support for up to 256 VLANs with a VLAN ID range of 2-4093. IEEE 802.1X Access Control Authentication of network users on a per port basis prior to permitting network access. Port authentication includes RADIUS assigned VLAN, dynamic VLAN creation, guest VLAN or into an unauthenticated VLAN. Automatic Denial-of-Service Protection Monitors for malicious attacks and protects the network by blocking the attacks. Packet Storm Protection Protects against unknown unicast, broadcast and multicast storms with user-defined thresholds. RADIUS The switch supports RADIUS authentication with primary and backup server configuration. Automatic VLAN Assignment - RADIUS Assigned VLANs Automatically assigns users to the appropriate VLAN based on their identity and location. RADIUS Accounting A robust set of attributes and statistics are available for collecting information from the switch. Management VLAN ID Provides secure management access to administrators in the specified VLAN. Link Flap Prevention Minimizes the network disruption by automatically detecting and disabling ports that experience link flap events. Performance and Efficiency Energy Efficient Ethernet (EEE) Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity. Auto-Port Shut Down The switch saves power by automatically shutting down power to inactive ports. Power is restored on a port upon link detection. Energy Savings Status The switch provides an estimated cumulative energy savings due to green Ethernet features being enabled. Energy-Efficient Cooling Includes variable speed fans operating only at the speed necessary to maintain operating temperature to reduce excess noise and power consumption. Fan-Less Operation Fan-less design for 8-port models, 24- and 48-port non-PoE models, making the switches ideal for office deployments. Switching Features IEEE 802.3x Flow Control Provides a flow-throttling mechanism propagated through the network to prevent packet loss at a congested node. Spanning Tree Protocol (STP) Supports standard IEEE 802.1D STP, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for faster convergence, and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP on local web). Loop Protection If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid broadcast storms. BPDU Filtering Drops BPDU packets when STP is enabled globally but disabled on a specific port. Jumbo Frame Support Supports up to 9216 bytes frame size to improve the performance of large data transfers. IGMP Snooping v1/v2 Improves network performance through multicast filtering, instead of flooding traffic on all ports. Link Aggregation Groups together multiple ports up to a maximum of eight (8) ports per trunk automatically using Link Aggregation Control Protocol (LACP), or manually, to form a high-bandwidth connection to the network backbone that helps prevent traffic bottlenecks. The 8-port models support 4 trunks, 24-port models support 8 trunks, and 48-port models support 16 trunks. LLDP/LLDP-MED (Media Endpoint Discovery) Defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN for automatic configuration of network devices such as IP phones.

Packet Storm Protection Protects against unknown unicast, broadcast and multicast storms with user-defined thresholds. RADIUS The switch supports RADIUS authentication with primary and backup server configuration. Automatic VLAN Assignment - RADIUS Assigned VLANs Automatically assigns users to the appropriate VLAN based on their identity and location. RADIUS Accounting A robust set of attributes and statistics are available for collecting information from the switch. Management VLAN ID Provides secure management access to administrators in the specified VLAN. Link Flap Prevention Minimizes the network disruption by automatically detecting and disabling ports that experience link flap events. Performance and Efficiency Energy Efficient Ethernet (EEE) Compliant with IEEE 802.3az standard requirements to save energy during periods of low data activity. Auto-Port Shut Down The switch saves power by automatically shutting down power to inactive ports. Power is restored on a port upon link detection. Energy Savings Status The switch provides an estimated cumulative energy savings due to green Ethernet features being enabled. Energy-Efficient Cooling Includes variable speed fans operating only at the speed necessary to maintain operating temperature to reduce excess noise and power consumption. Fan-Less Operation Fan-less design for 8-port models, 24- and 48-port non-PoE models, making the switches ideal for office deployments. Switching Features IEEE 802.3x Flow Control Provides a flow-throttling mechanism propagated through the network to prevent packet loss at a congested node. Spanning Tree Protocol (STP) Supports standard IEEE 802.1D STP, IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) for faster convergence, and IEEE 802.1s Multiple Spanning Tree Protocol (MSTP on local web). Loop Protection If the switch detects a loop, it disables the source port from forwarding data packets originating from the switch to avoid broadcast storms. BPDU Filtering Drops BPDU packets when STP is enabled globally but disabled on a specific port. Jumbo Frame Support Supports up to 9216 bytes frame size to improve the performance of large data transfers. IGMP Snooping v1/v2 Improves network performance through multicast filtering, instead of flooding traffic on all ports. Link Aggregation Groups together multiple ports up to a maximum of eight (8) ports per trunk automatically using Link Aggregation Control Protocol (LACP), or manually, to form a high-bandwidth connection to the network backbone that helps prevent traffic bottlenecks. The 8-port models support 4 trunks, 24-port models support 8 trunks, and 48-port models support 16 trunks. LLDP/LLDP-MED (Media Endpoint Discovery) Defines a standard extension of LLDP that stores values for parameters such as QoS and VLAN for automatic configuration of network devices such as IP phones. Address Resolution Protocol (ARP) The ARP table displays all of the IP addresses that have been resolved to MAC addresses, either dynamically or through static entry configuration. Additional Features Accessed Through Local Web-Management Interface Top Event Dashboard Provides notifications for critical events and a quick access to the latest log events. Quick Start-Up and VLAN Wizard Enables automatic configuring of the initial settings such IP address, device information, and system time.

From #1 New York Times bestselling author Lisa See, “one of those special writers capable of delivering both poetry and plot” (The New York Times Book Review), a moving novel about tradition, tea farming, and the bonds between mothers and daughters.In their remote mountain village, Li-yan and her family align their lives around the seasons and the farming of tea. For the Akha people, ensconced in ritual and routine, life goes on as it has for generations—until a stranger appears at the village gate in a jeep, the first automobile any of the villagers has ever seen. The stranger’s arrival marks the first entrance of the modern world in the lives of the Akha people. Slowly, Li-yan, one of the few educated girls on her mountain, begins to reject the customs that shaped her early life. When she has a baby out of wedlock—conceived with a man her parents consider a poor choice—she rejects the tradition that would compel her to give the child over to be killed, and instead leaves her, wrapped in a blanket with a tea cake tucked in its folds, near an orphanage in a nearby city. As Li-yan comes into herself, leaving her insular village for an education, a business, and city life, her daughter, Haley, is raised in California by loving adoptive parents. Despite her privileged childhood, Haley wonders about her origins. Across the ocean Li-yan longs for her lost daughter. Over the course of years, each searches for meaning in the study of Pu’er, the tea that has shaped their family’s destiny for centuries. A powerful story about circumstances, culture, and distance, The Tea Girl of Hummingbird Lane paints an unforgettable portrait of a little known region and its people and celebrates the bond of family.

With a single announcement from a herald, all the cities of Greece and Asia had been set free; only an intrepid soul could formulate such an ambitious project, only phenomenal valour and fortune bring it to fruition. (Livy, 33. 33) Thus Livy describes the reaction to the Roman commander T.Q. Flamininus proclamation of the freedom of Greece at the Isthmian games near Corinth in 196 BC. Half a century later Greece was annexed as a province of the Romans who burned the ancient city of Corinth to the ground. Books 31 to 40 of Livy s history chart Rome s emergence as an imperial nation and the Romans tempestuous involvement with Greece, Macedonia and the near East in the opening decades of the second century BC; they are our most important source for Graeco-Roman relations in that century. Livy s dramatic narrative includes the Roman campaigns in Spain and against the Gallic tribes of Northern Italy; the flight of Hannibal from Carthage and his death in the East; the debate on the Oppian law; and the Bacchanalian Episode. This is the only unabridged English translation of Books 31 to 40.The complete Livy in English, available in five volumes from Oxford World s Classics. ABOUT THE SERIES: For over 100 years Oxford World s Classics has made available the widest range of literature from around the globe. Each affordable volume reflects Oxford s commitment to scholarship, providing the most accurate text plus a wealth of other valuable features, including expert introductions by leading authorities, helpful notes to clarify the text, up-to-date bibliographies for further study, and much more.

A masterful new translation of Suetonius renowned biography of the twelve Caesars, bringing to life a portrait of the first Roman emperors in stunning detailThe ancient Roman empire was the supreme arena, where emperors had no choice but to fight, to thrill, to dazzle. To rule as a Caesar was to stand as an actor upon the great stage of the world. No biography invites us into the lives of the Caesars more vividly or intimately than that by Gaius Suetonius Tranquillus, written from the centre of Rome and power, in AD 121.Placing each Caesar in the context of the generations that had gone before, and connecting personality with policy, Suetonius injected flesh and blood into their stories, which continue to inform how we understand the drama of power today. Their shortfalls, foreign policy crises and sex scandals are laid bare; we are shown their tastes, their foibles, their eccentricities; and we sit at their tables and enter their bedrooms, resulting in a series of biographies mediated through the lives of the Caesars themselves.That Rome lives more vividly in people s imagination than any other ancient empire owes an inordinate amount to Suetonius, and now award-winning author and translator Tom Holland brings us even closer in a new, spellbinding translation. Giving a deeper understanding of the personal lives of the Caesars and of how they inevitably informed what happened across the vast expanse of empire, The Lives of the Caesars is an astonishing, immersive experience of a time and culture at once familiar and utterly alien to our own.

A spectacular, vivid, groundbreaking work of history which takes us into the minds and lives of medieval women.What was life really like for women in the medieval period? How did they think about sex, death and God? Could they live independent lives? And how can we hear the stories of women from this period?Few women had the luxury of writing down their thoughts and feelings during medieval times. But remarkably, there are at least four extraordinary women who did. Those women were: Marie de France, a poet; Julian of Norwich, a mystic and anchoress; Christine de Pizan, a widow and court writer; and Margery Kempe, a no-good wife . In their own ways these four very different writers pushed back against the misogyny of the period. Each of them broke new ground in womenâs writing and left us incredible insights into the world of medieval life and politics.Hetta Howes has spent her working life uncovering these womenâs stories to give us a valuable and unique historical biography of their lives that challenges what we hold to be common knowledge about medieval women in Europe.

A BEHIND THE SCENES GLIMPSE INTO THE LIVES OF HENRY VIII, ANNE BOLEYN, ELIZABETH I AND MORE: PERFECT FOR FANS OF WOLF HALL Readers LOVE The Private Lives of the Tudors: A truly informative and thoroughly enjoyable read. ⭐⭐⭐⭐⭐ It was an absolutely delight, and I read it in record time ⭐⭐⭐⭐⭐ I found this book riveting and took it on holiday! ⭐⭐⭐⭐⭐ ---- I do not live in a corner. A thousand eyes see all I do. Elizabeth IThe Tudor monarchs were constantly surrounded by an army of attendants, courtiers and ministers. Even in their most private moments, they were accompanied by a servant specifically appointed for the task. A groom of the stool would stand patiently by as Henry VIII performed his daily purges, and when Elizabeth I retired for the evening, one of her female servants would sleep at the end of her bed.These attendants knew the truth behind the glamorous exterior. They saw the tears shed by Henry VII upon the death of his son Arthur. They knew the tragic secret behind Bloody Mary s phantom pregnancies. And they saw the crooked carcass beneath Elizabeth I s carefully applied makeup, gowns and accessories.It is the accounts of these eyewitnesses, as well as a rich array of other contemporary sources that historian Tracy Borman has examined more closely than ever before. With new insights and discoveries, and in the same way that she brilliantly illuminated the real Thomas Cromwell - The Private Life of the Tudors will reveal previously unexamined details about the characters we think we know so well.----Critical acclaim for The Private Lives of the Tudors: Borman approaches her topic with huge enthusiasm and a keen eye for entertaining...this is a very human story of a remarkable family, full of vignettes that sit long in the mind. Dan Jones, The Sunday Times Tracy Borman s eye for detail is impressive; the book is packed with fascinating courtly minutiae... this is a wonderful book.

This book complements the authorâ ™s previous book on the Chester and Holyhead Railway and completes the story of railways associated with the London and North Western Railway in north Wales. It does so by breaking down developments to three districts working from east to west across the region. The book examines the background to the construction of the branch lines in the context of relevant wider railway developments. It provides an account of the operation of each of the lines with reference to significant incidents on the railway and the relationship of the branch to the communities it served. The dominance of railways peaked around 1914 so the book analyses the process of decline from that status. That decline was relatively rapid and featured several rounds of closures of stations and branches, culminating in the notorious Beeching cuts of the 1960s that eventually left north Wales with fewer than fifty miles of branch railways â “ under 20% of the original total. The book has maps and tables that provide an overview of the detail contained in the text and the 150 photographs. The book concludes with an overview of the railway system in north Wales. It reflects on how reductions might have been made without depriving so much of the region of a presence on the network, and how the railway policies adopted by private companies and the later nationalized industry paid too little attention to the relationship between the region and its trains.

Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes and Mary Jane Kelly are inextricably linked in history. Their names might not be instantly recognisable, and the identity of their murderer may have eluded detectives and historians throughout the years, but there is no mistaking the infamy of Jack the Ripper. For nine weeks during the autumn of 1888, the Whitechapel Murderer brought terror to Londonâ ™s East End, slashing womenâ ™s throats and disembowelling them. Londonâ ™s most famous serial killer has been pored over time and again, yet his victims have been sorely neglected, reduced to the simple label: prostitute. The lives of these five women are rags-to-riches-to-rags stories of the most tragic kind. There was a time in each of their lives when these poor women had a job, money, a home and a family. Hardworking, determined and fiercely independent individuals, it was bad luck, or a wrong turn here or there, that left them wretched and destitute. Ignored by the press and overlooked by historians, it is time their stories were told.

A revisionist, completely accessible and radically inclusive history of maths Lively, satisfying, good at explaining difficult concepts The Sunday TimesMathematics shapes almost everything we do. But despite its reputation as the study of fundamental truths, the stories we have been told about it are wrong. In The Secret Lives of Numbers, historian Kate Kitagawa and journalist Timothy Revell introduce readers to the mathematical boundary-smashers who have been erased by history because of their race, gender or nationality.From the brilliant Arabic scholars of the ninth-century House of Wisdom, and the pioneering African American mathematicians of the twentieth century, to the lady computers around the world who revolutionised our knowledge of the night sky, we meet these fascinating trailblazers and see how they contributed to our global knowledge today.Along the way, the mathematics itself is explained extremely clearly, for example, calculus is described using the authors home baking, as they pose the question: how much cake is in our cake? This revisionist, completely accessible and radically inclusive history of mathematics is as entertaining as it is important.
