The 3Com 3CR17162-91 Switch 5500-EI 48-ports operate at 10/100 speeds while an additional four active ports can be customized using SFP modules for copper or fiber Gigabit uplinks or integrated stacking. The 3Com Switch 5500-EI 52-Port is a premium stackable 10/100 switch with Enhanced Image (EI) software for businesses running the most demanding network applications requiring the highest "five 9s" network uptime.48 10/100 ports, with 4 SFP slots Scalable stackable design with resilient stacking up to eig..
This cable is used between the top and bottom units of a stack of 3Com Switch 5500G-EI switches, so as to add resiliency to the 3Com eight-high XRN Stacking. Each Switch 5500G has two built-in XRN Stacking ports at the rear of the unit. For non-resilient stacking, a 3Com Switch 5500G Stacking Cable goes from the first stacking port of one switch to the second stacking port of the next switch, in and out, switch to switch, down the stack. This Resilient Stacking Cable then completes the stacking loop by conn..
The 3Com switch 5500G-EI 24-Port comes with a field-upgradeable PSU allowing a customer to add, after initial installation of the switch, Power over Ethernet (PoE) capabilities - providing inline power to attached devices including Voice over IP (VoIP) phones, access points, etc.To simplify sparing and support of units with this flexible configuration, 3Com has assigned a non-orderable SKU to a unit without a PSU.This chassis is not separately orderable; it is only available, with a PSU pre-installed.The ..
The 3Com Switch 5500G-EI is a premium managed Gigabit switch with advanced features, perfect for medium-sized businesses looking to deploy advanced edge applications. Layer 3 routing makes the Switch 5500 ideal for businesses looking to deploy the most advanced applications.The Switch 5500G-EI PWR 48-port features 44 Gigabit ports, four dual-personality ports, operating either as 10/100/1000 or SFP-based fiber and one expansion module slot. Patented XRN stacking technology provides 8-high multi-layer stacki..
The power supply in the 3Com Switch 5500G-EI 48-Port PWR is field-replaceable for ease of service. This unit may also be used to field-upgrade the non-PoE 3Com Switch 5500G-EI 48-Port to Power over Ethernet (PoE) capabilities...

* High performance, resilient, convergence-ready, Copper Gigabit Ethernet * This module delivers twenty ports of high-performance Gigabit Ethernet switching over Category 5 twisted-pair cable. * Switch 7700 modules support on-board or Local Layer 2 switching, allowing packets to remain local to the module, which reduces backplane and switch fabric loading. * This reduces congestion in the network minimizing packet loss, to enable applications to run faster across the network. The reduction in latencies will..
This module delivers twenty ports of high-performance Gigabit Ethernet switching with optional Small Form-Factor Plug-in (SFP) ports for both fiber and copper connections. Switch 7700 modules support on-board or Local Layer 2 switching, allowing packets to remain local to the module, which reduces backplane and switch fabric loading...
The Switch Fabric Module is the core of the 3Com Switch 7700 system. The Switch Fabric performs route calculation and provides all Layer 3 switching functionality. It also performs Layer 2 switching between interface modules and where on-board Layer 2 switching is not possible. Based on the address-forwarding table, the hardware performs line-speed switching of Layer 2 / Layer 3 data packets. VLANs, link aggregation, QoS traffic classification and prioritization, and ACLs (Access Control Lists) are also sup..
All Switch 7700R/Switch 7700 Starter Kits come with two AC power supplies. Order this component to have a third AC power supply to provide N+1 power redundancy for either model switch. Or, order to have spare or replacement AC power supply. The 3Com Switch 7700 AC Power Supply can operate in both a Switch 7700R 8-Slot chassis and Switch 7700 7-Slot chassis...
