Repackaging the gateway accessories
Repackaging the power module
CAUTION:
Before removing a power module, switch off the circuit breakers at the input end of all power cables, and
remove all the power cables to avoid device damage and bodily injury.
To repackage a power module:
1. Prepare the packing bag and box of the power module. Make sure the bag is clean, dry, and not
damaged.
2. Remove all power modules from the chassis, and then install blank filler panels to the empty slots.
For how to remove a power module and install a blank filler panel, see "Replacing FRUs."
3. Put the power module into the bag.
4. Put the packed power module into the box. Place the power module in a correct direction onto the
foam cushion in the box; otherwise, the power module cannot be completely seated into the foam
cushion.
