PA-MC-STM-1SMI: Alarm LED Amber!!!

[yogesh rajguru]

We are having Cisco 7206VXR with NPEG2 and the IOS c7200p-spservicesk9-mz.124-15.T10.bin.

PA-MC-STM-1SMI is connected to 3rd Slot of the Chassis. The Links terminated on the SMI are working fine and we are not getting any Error Messages on Chassis regarding the this SMI.

But here we have Amber LED Glowing on ALARM LED of the SMI Card.

As per the below Link:

http://www.cisco.com/en/US/docs/interfaces_modules/port_adapters/install_upgrade/multichannel_serial/multichannel-stm-1_install_config/2746ovr.html#wp1030088

This means Loss of Signal/Frame.

Table 1-5     PA-MC-STM-1 LEDs

LED Label	Color	State	Meaning
ENABLED	Green	On	Port adapter is enabled for operation.
RxCXR	Green	On	Indicates the PA-MC-STM-1 is receiving a good SDH signal.
Alarm	Yellow	On	Indicates an SDH/E1 signal error such as LOS1 or LOF2 .

¹ LOS = loss of signal

² LOF = loss of frame

But in our scenario, there is nothing like service Loss or Impact.

The same has been resolved by shutting the unwanted/unsed Controller Interfaces on the Controller.

If the Controller interefaces are unused then for best practice it has to be shut.
