Juniper Networks Juniper M-series M10i - Manual (Page 45)

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 8 on page 45
12-port PIC:
■ Connector: One very High Density Connector Interface (VHDCI) to RJ-21 cable that
connects to an RJ-45 patch panel
Cables and connectors
Status LED, 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 port LEDs per port:
■ 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.
■ Port 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 port 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.
