When a module appears as Unknown on the show module command output, make sure you check these:

•The supervisor engine and the software it runs support the module.

•The specifications of the module. Make sure the module can be inserted in any slot or if it can only be inserted in specific slots.

Note: For both options, check the Release Notes of the software version that the supervisor engine runs.

Module Status is Unknown / PwrDeny

After you insert a module, the status of it is PwrDeny. If this is the case, check if there is enough power to turn on the module that appears as PwrDeny.
