What It Means

For all routers except the M160 and T320 routers and the T640 routing node, the command output displays the power supply slot number, revision level, part number, serial number, and the power supply type. When facing the back of the router, power supply A is located on the right and power supply B is located on the left.

For the M160 and T320 routers and the T640 routing node, the command output displays the power supply or PEM slot number, revision level, part number, serial number, and power supply type. When facing the back of the router, PEM 0 is located on the right and PEM 1 is located on the left.
