Replacing Power Supplies (9-Slot Chassis)

If a power supply ever needs to be replaced in an Omni Switch/Router 9-slot Chassis (e.g.,
OmniS/R-9 or OmniS/R-9p), it is strongly recommended that power supplies not be mixed,
except under the conditions and exceptions shown in the following table.
Note
In all cases, swapping operations must be made with
the power switch of the replacement power supply
turned OFF. Failure to turn the power switch off during
the swapping operation may cause the data switch to
reset and restart.
