Detailed explanation-1: -Service Module Slots are used for router modules that run specific services that could be either Cisco proprietory or third party applications. These modules have their own processors, memory etc and don’t use any of the router’s resources.

Detailed explanation-2: -The Cisco IOS® command-line interface (CLI) offers context-sensitive help, a useful tool if you are a new user because at any time during an EXEC session, you can type a question mark (?) to get help. Two types of context-sensitive help are available: word help and command syntax help.

Detailed explanation-3: -Log in to the switch console to run the privileged EXEC mode of the Cisco switch, use the fiber-ports-optical-transceiver command. The Output Power (mWatt) field in the command output indicates the received power of the optical module, and the Input Power (mWatt) field indicates the transmit power.
