I/O Module LEDs
This section describes the LED activity on the BlackDiamond I/O modules:
• Table 60 describes the LED activity on the Ethernet I/O modules
• Table 61 describes the LED activity on the PoS and ATM modules
• Table 62 describes the LED activity on the ARM and MPLS modules
1 If you have a PoS module, the link is up, but the PPP/VLAN interface might not be up. To determine whether PPP is up, use
the
show ppp command to display PPP status information.
