| | The Ethernet Routing Switch 5520-48T-PWR PoE Switch features 48 10/100/1000BASE-T RJ-45 ports for desktop switching and four built-in SFP (Small Form Factor Pluggable) GBIC ports for uplink. Ports 45, 46, 47, and 48 offer configuration flexibility by allowing the network administrator to configure each port as either 10/100/1000 or make use of the built-in SFP GBIC. However, power will still be provided from ports 45-48 and can be used to troubleshoot or power any 802.3af compliant device that only requires power and not a data connection. As many as eight Ethernet Routing Switch 5520-48T-PWR Switches can be stacked to achieve up to 384 10/100/1000 ports for highest-density desktop switching.
The Ethernet Routing Switch 5520 Switch is IEEE 802.3af compliant. It 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 Ethernet Routing Switch 5520-48T-PWR Switch can supply power up to 15.4 W per port (with the addition of the Ethernet Routing Switch 15 PSU and RPSU module). Without Ethernet Routing Switch 15 Power Supply Unit (PSU), the Ethernet Routing Switch 5520-48T Switch would supply an average of 6.5 W per port (ports can exceed 6.5 W per port as long as the total of all ports requiring power does not exceed 320 W).
The Ethernet Routing Switch 5520 Switch automatically recognizes the connection of a Power over Ethernet device and immediately send power to it. This automatic capability ensures fast connectivity without manual intervention.
Each port can be configured to limit the power delivered to a device. Each port can also be configured for power priority level—low, high, and critical. On the switch, total available power is monitored. In the case where all available power is fully utilized, the switch may turn off lower priority ports and turn on higher priority ports.
The Ethernet Routing Switch 5520 Switch can automatically disable a port if there is a short. All the other ports on the switch will remain active and will not be affected by the disabled port.
The Ethernet Routing Switch 5520 Switches provide simplified Web-based configurations on data and power properties. The graphical user interfaces make it simple to set up data and power configurations.
With the Ethernet Routing Switch 5520 Switches, data and power can be transmitted over one cable without using a power outlet. There is no need for a separate cable connecting the device to a power outlet.
The Ethernet Routing Switch 5520 Switch supports the DHCP (Dynamic Host Configuration Protocol) Relay feature that provides the system with the ability to relay DHCP requests to the DHCP server and eliminates the need for a DHCP server on every subnet. It forwards a request for an IP address from a client to a DHCP server across subnets.
Ethernet Routing Switch 5520 Switch has four built-in SFP GBIC ports for dedicated uplink connectivity to network core switches such as the ERS 8600. This increases the uplink bandwidth as GBIC ports are not required for stacking purposes. Using the proven Distributed Multi-Link Trunking (DMLT) resiliency feature, up to 32 GBIC ports are available for pure uplink connectivity in a full stack among the highest in the market. Ethernet Routing Switch 5000 Switches have also been architected to support future technologies such as 10 Gigabit uplinks. |
