Chassis Power Up
With N+1 PSU redundancy the chassis must be started with a full complement of possi-
ble PSUs, thereafter it can run on one less than the total number of PSUs. This final PSU
is redundant and allows for hot swapping a PSU should one fail. Connecting the PSUs to
different AC lines provides AC failover protection.
The system should continue to run and allow a hot swap of a defective PSU. Should
there not be enough power to keep all of the leafs running, FabricIT EFM may power
down some leafs. If this happens it will be necessary to reboot the chassis once the defec-
tive PSU has been replaced.
1. Check all FRUs for proper insertion and seating before connecting the AC power
cords.

• Power supplies
• Leaf fan modules

2. Insert all leafs that you plan to use, in the chassis. Start at the bottom of the chassis
and work your way up.
3. Insert the first two spines in the top two slots.
4. Insert the rest of the spines from the bottom of the chassis up to slot #3.
5. Insert thermal blanks in unused leaf slots to maintain balanced air flow.
6. Tighten all leaf and spine mounting screws.
7. Connect the power cords to the PSUs.
8. Connect the power cords to grounded electrical outlets.
