Introduction

This document describes the troubleshooting and workaround in order to clear the Out-Of-Service state on NCS4200-3GMS for the 4202 chassis module.

Problem

NCS4200-3GMS card shows an Out-Of-Service state and is down.

Observation

- NCS4200-3GMS card shows an Out-Of-Service state and is down

- Swapped the card to the other chassis and no noticeable change

- Similarly, if you insert the fresh new card to this node, still you see the same status as that does not help to fix the issue

- There is more chance that the issue occurs on software version less than 17.9.4

Solution

- Perform a hard reset on the card

- Perform a hard reset to the card via the CLI command:

# config t

# hw-module subslot (slot number) shutdown unpowered

- After a few minutes, run the CLI commands in order to unshut the card:

# no hw-module subslot (slot number) shutdown unpowered

- If the hard reset does not help, then take DB backup from the node and copy it to the local machine; accomplish the reload to the chassis via this command:

# reload

#Yes

- Wait for the node to boot up

- Issue resolved after node reload can be monitored for stability

- If the issue is still seen, then try to accomplish a power cycle

- If not, then probably you must check the backplane of the chassis
