For each PEM, the command output displays the slot number, status, temperature, DC
input and output, load percentage, and voltage. You can display the status of a particular
power supply by specifying the slot number.
For T320, T640, T1600, TX Matrix, and TX Matrix Plus routers, the command output
displays the PEM slot number, status, temperature, DC input status, and DC output for
each Flexible PIC Concentrator (FPC), SONET Clock Generator (SCG), Control Board,
and Switch Interface Board (SIB). You can display the status of a particular power supply
by specifying the slot number.
