Meaning The show chassis environment mcs command is available on the M40e and M160 routers
only. The command output displays environmental information about both MCSs installed

or Empty. The command also indicates that the MCS is the master MCS. The command
output also displays the temperature of the air flowing past the MCS, information about
MCS power supplies, field-programmable gate array (FPGA) revision information, and
the revision level of the chassis management bus (CMB) backup.
