| | ERS 5520 Switches are one rack unit high stackable 10/100/1000Mbps Ethernet Layer 3 routing switches designed to provide high-density Gigabit desktop connectivity and Power over Ethernet capability to mid-size and large enterprise customers’ wiring closets.
ERS 5520-24T-PWR Switch with 24 10/100/1000BASE-T RJ-45 ports—they feature four built-in SFP GBIC ports for uplink. Models may be stacked with each other or in stacks of eight units, to achieve a maximum of 384 10/100/1000 ports for high-density desktop switching. These models will also be able to stack with the ERS 5510 Switches and future ERS 5000 models.
The ERS 5520-24T-PWR PoE Switch offers 24 10/100/1000BASE-T RJ-45 ports for desktop switching and four built-in GBIC ports for uplink. Ports 21, 22, 23, and 24 offer configuration flexibility as either a 10/100/ 1000 or a built-in SFP GBIC port. However, power will still be provided from ports 21-24 and can be used to troubleshoot or power any 802.3af compliant device that only requires power and not a data connection. Both ERS 5520-24T-PWR and ERS 5520-48T-PWR Switches may be combined in a single stack for maximum flexibility.
The ERS 5520 Switches are IEEE 802.3af compliant. They can provide Power over Ethernet to any IEEE 802.3af compliant device such as IP phones, wireless access points, network cameras, security and lighting devices, and access control devices. The benefit of being interoperable with standards-based equipment means that customers are not forced to tie themselves to any one vendor, as the switches have the flexibility to power multiple vendors’ devices. The ERS 5520-24T-PWR Switch can supply up to 15.4 W per port as well (with the addition of the ERS RPS 15 PSU). Without ERS RPS 15 PSU, the ERS 5520-24TPWR Switch would supply an average of 13 W per port (ports can exceed 13 W per port as long as the total of all ports requiring power does not exceed 320 W). |
