Description	4 or 12 100Base-TX ports; 8 100Base-FX ports Power requirement: 4-port: 0.14 A @ 48 V (6.8 W) 8-port: 0.26 A @ 48 V (12.5 W) 12-port: 0.23 A @ 48 V (11 W)
Hardware features	High-performance throughput on each port at speeds up to 100 Mbps Source and destination Media Access Control (MAC) address filtering RMON EtherStats packet buffering 802.3 Ethernet standard compliant 4-port PICs support MTUs of up to 9192 bytes; 8-port and 12-port PICs support MTUs of up to 1532 bytes 4-port PICs support 1024 802.1Q VLANs per port; 8-port and 12-port PICs support 16 802.1Q VLANs per port
Software features	Auto sensing full-duplex and half-duplex modes Virtual Router Redundancy Protocol (VRRP) 802.1Q virtual LANs (VLANs) Circuit cross-connect (CCC) VLAN
Cables and connectors	4-port PIC: Connector: Two-pair, category 5 unshielded twisted-pair connectivity through an RJ-45 connector Pinout: MDI noncrossover 8-port PIC: Connector: MT-RJ female FX optical interface—see Table 6 12-port PIC: Connector: One very High Density Connector Interface (VHDCI) to RJ-21 cable that connects to an RJ-45 patch panel
LEDs	Status LEDs, one bicolor: Off—PIC ports not enabled Green—PIC is operating normally Red—PIC has an error or failure 4-port PIC—One pair of port LEDs: Link LED—If green, the port is online; if there is no light, the port is down RX LED—If flashing green, the port is receiving data; if there is no light, the port might be on, but is not receiving data 8-port PIC—one pair of LEDs per port: Link LED—If green, the port is online; if there is no light, the port is down Note: The Link LED remains lit on the 8-port PIC when the port is down. RX LED—If flashing green, the port is receiving data; if there is no light, the port might be on, but is not receiving data 12-port PIC—one LED per port: Green—100-Mbps link established Flashing green—100-Mbps activity Yellow—10-Mbps link established Flashing yellow—10-Mbps activity Off—No link present Note: The port LEDs remains lit on the 12-port PIC when the ports are down.
