- 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: FX optical interface—see Gigabit Ethernet 1000BASE Optical Interface Specifications 12-port PIC: - Connector: One very high density connector interface (VHDCI)
to RJ-21 cable that connects to an RJ-45 patch panel
|
| | 48-port PIC: - VHDCI to RJ-21 cables that connect to an RJ-45 patch
panel
- Four VHDCI connectors that each service 12 10/100 ports
Note:
Each of the four connectors on a Fast Ethernet
48-port PIC can support a maximum of approximately 800 Mbps. However,
this constitutes oversubscription. Use this PIC only in environments
that can support this level of oversubscription. |
LEDs | 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: 12-port PIC—one port LED per port: |
| | Note:
The 48-port PIC does not have port LEDs. To check port
status on a 48-port PIC, use the show interfaces fe-fpc/pic/port command. For more information about this command, see the Junos OS Network Interfaces Configuration Guide. |
