Troubleshooting Wideband Components
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.
Action
More Information or Example
Step 1
Use the
show diag
command to check that a
Wideband SIP is powered on.
Router#
show diag 1/0
Slot/Subslot 1/0:
2jacket-1 card
, 0 ports
Card is full slot size
Card is analyzed
Card detected 0:3:16 ago
Card uptime 0 days, 0 hours, 3 minutes, 17 seconds
...
If
show diag
displays output, the Wideband SIP is powered on. If
show diag
displays no output, the Wideband SIP is not powered on.
Step 2
Check that the Wideband SIP’s FAIL LED is
not 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.
Step 3
Use the
show hw-module bay oir
command
to check that a Wideband SPA is powered on.
Router#
show hw-module bay 1/0/0 oir
Module
Model
Operational Status
------------- -------------------- ------------------------
bay 1/0/0
SPA-24XDS-SFP
ok
•
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.
Step 4
Check that the Wideband SPA’s STATUS
LED is lighted green.
•
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.
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.
•
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.
