Chassis Slot Numbering
The term slot refers to the position at which a CMM or NI module is installed in chassis. CMM slot posi-
tions are designated as Slot A and Slot B. On OS7700 switches, NI slot numbers range from 1 to 8. On
OS7800 switches, NI slot numbers range from 1 to 16.
Power supply bays are also given specific slot numbers. On OS7700 switches, power supply slot numbers
are designated PS-1 through PS-3, from top to bottom. On OS7800 switches, power supply slot numbers
are designated PS-1 through PS-4, from top to bottom.
