Troubleshooting Wideband Components
Action
Step 1
Use the show diag command to check that a
Wideband SIP is powered on.
Step 2 Check that the Wideband SIP's FAIL LED is
not on.
Step 3 Use the show hw-module bay oir command
to check that a Wideband SPA is powered on.
Step 4 Check that the Wideband SPA's STATUS
LED is lighted green.
Step 5
If cables are connected to one or both of the
SPA's Gigabit Ethernet port SFPs and the
links for these should be up, check that the
Wideband SPA's two A/L (Active Loopback)
LEDs are lighted green.
Verifying That a Wideband SPA's Active Gigabit Ethernet Port Is Up
The Gigabit Ethernet ports on a Wideband SPA are not considered standard user-configurable interfaces
and do not appear in the output of the show interfaces command. The Wideband SPA is a controller with
one active and one redundant Gigabit Ethernet port. The show controller modular-cable command
displays information about the SPA, its Gigabit Ethernet active port, installed Small Form-Factor
Pluggable (SFP) modules, and so on.
The following example provides sample show controller modular-cable output for the Wideband SPA
located in slot 1, subslot 0, bay 0 of a Cisco uBR10012 router.

If show diag displays output, the Wideband SIP is powered on. If
show diag displays no output, the Wideband SIP is not powered on.
The FAIL LED is turned on by default and turned off by software
after basic board functionality has been verified. If the SIP's FAIL
LED remains on, the SIP has failed to initialize or has encountered
an error.

If the Operational Status is "ok", the Wideband SPA is powered
•
on and operational.
If the Operational Status is "admin down", the Wideband SPA is
•
not powered on.
If the STATUS LED is green, the SPA is ready and operational.
•
If the STATUS LED is amber, SPA power is on and good, and the
•
SPA is being configured.
If the STATUS LED is off, SPA power is off.
•
• If the A/L LED is green, the port is enabled and the link is up.
• If the A/L LED is amber, the port is enabled and the link is down.
If the A/L LED is off, the port is not enabled.
