Troubleshooting ESM - LEDs Solid On

Note: The ESM can be replaced without powering off. Leave the enclosure powered on.

Use CLI CMD poa to check if the ESM is in Lock Down mode.
If the ESM is in Lock Down mode, try the following:
1. Reset the ESM.
2. Upgrade ESM firmware to same version as peer's ESM.
3. If resetting and upgrading do not work, remove the ESM and verify that the pins on the backplane and ESM are not bent. See: ESM Canister Removal. Replace ESM with another one if any physical damage is found, which should have the same FW version with the peer ESM. For installation, see: ESM Canister Installation
If no lock down mode is found, use CLI CMDs temp get, fan get , and power get to check for component faults.
If any faults are found, replace related faulted devices and keep watching the system for a period of time to check whether this fault can be recovered.
If the fault still exists, remove the ESM and verify that the pins on the backplane and ESM are not bent. See: ESM Canister Removal to remove the canister. For canister installation, see: ESM Canister Installation
