Netgear M4100-50G-POE+ 48-Port Gigabit L2+ Managed Switch REFURB GSM7248P-100NES

REFURBISHED WITH A 90 DAY CCS WARRANTY!!! The NETGEAR Intelligent Edge M4100 series consists of 9 fully managed switches, ranging from 12-port to 50-port Fast and Gigabit Ethernet. They are ideal for all organizations considering reliable, affordable and simple access layer switching with CLI, advanced scripting capabilities and Layer 3 routing. As a cost-effective component of converged voice, video and data networking solutions, NETGEAR M4100 series delivers a secure edge in commercial buildings and campus LAN environments: PoE (802.3af) and PoE+ (802.3at) versions of M4100 series are perfect for Wireless access points, IP telephony and IP surveillance deployments. High availability and PoE/PoE+ full power capability Industry standard management Industry leading warranty Layer 2+ with static routing Engineered for convergence Layer 3 hardware with L2+ software affordability Built upon L3 hardware platform while Layer 2+ software package allows for better budget optimization Uses latest generation silicon low-power 40-nanometer technology L2 and L3 switching features (access control list, classification, filtering, IPv4 routing) are performed in hardware at interface line rate for voice, video, and data convergence Layer 2+ software package provides straight forward IP static routing capabilities for physical interfaces, VLANs and subnets 16K MAC address table, 1K concurrent VLANs and 64 static routes for SMB and small enterprise access layers Increased packet buffering with up to 12 Mb dynamically shared accross all interfaces for most intensive applications IEEE 802.3af Power over Ethernet (PoE) provides up to 15.4W per port IEEE 802.3at Power over Ethernet Plus (PoE+) provides up to 30W per port Desktop versions can be powered by upstream PoE+ switch M4100-D12G-POE+ can even redistribute PoE power from the upstream PoE+ switch to VoIP phones or other devices in meeting rooms, retail sales floors or other challenging environments without outlet Both IEEE 802.3at Layer 2 LLDP method and 802.3at 2-event classification methods are supported for compatibility with all PoE+ PD devices Automatic MDIX and Auto-negotiation on all ports select the right transmission modes (half or full duplex) as well as data transmission for crossover or straight-through cables dynamically for the admin 100Mbps backward compatiblity on all SFP ports IPv6 support with multicasting (MLD for IPv6 filtering), ACLs and QoS Traffic control MAC Filter and Port Security DHCP Snooping monitors DHCP traffic between DHCP clients and DHCP servers to filter harmful DHCP message and prevent DHCP spoofing attacks IP source guard and Dynamic ARP Inspection for malicious users traffic elimination Layer 2 / Layer 3-v4 / Layer 3-v6 / Layer 4 Access Control Lists (ACLs) can be binded to ports, Layer 2 interfaces, VLANs and LAGs (Link Aggregation Groups or Port channel) for fast unauthorized data prevention and right granularity Bridge protocol data unit (BPDU) Guard allows the network administrator to enforce the Spanning Tree (STP) domain borders and keep the active topology consistent and predictable - unauthorized devices or switches behind the edge ports that have BPDU enabled will not be able to influence the overall STP topology by creating loops Spanning Tree Root Guard (STRG) enforces the Layer 2 network topology by preventing rogue root bridges potential issues when for instance, unauthorized or unexpected new equipment in the network may accidentally become a root bridge for a given VLAN Dynamic 802.1x VLAN assignment mode, including Dynamic VLAN creation mode and Guest VLAN / Unauthenticated VLAN are supported for rigorous user and equipment RADIUS policy server enforcement 802.1x MAC Address Authentication Bypass (MAB) Double VLANs (DVLAN - QinQ) pass traffic from one customer domain to another through the "metro core" in a multi-tenancy environment UPC : 00606449088038
