The WS-C3550-24PWR-EMI is a Cisco Catalyst 3550 24-port 10/100 power over Ethernet switch with two GBIC-based Gigabit Ethernet slots. The EMI suffix marks the Enhanced Multilayer Software Image.
EMI is the Standard Multilayer Image (SMI) feature set plus more functionality, including IP unicast and multicast routing and WCCP. Inline power reaches up to 15.4W per 10/100 port, which feeds Cisco IP phones and Cisco Aironet wireless LAN access points straight from the switch and removes wall power and separate wiring for each device.
Switching and routing run at wire speed. Services include 802.1x, SSH, SNMPv3, ACLs, port security and RADIUS/TACACS+, and the switch supports clustering through the Cluster Management Suite. The 24PWR is compatible with the Cisco Redundant Power System 675 (RPS 675) and an uninterruptible power supply (UPS).
A 24-port PoE option from the Catalyst 3750G range is the WS-C3750G-24PS-S 24-port PoE switch, and Cisco switches holds more models.
