Chassis Power Up
Before starting any procedure on the IS5600 series chassis system put an ESD prevention
wrist strap on your wrist and connect to the IS5600 series chassis.
The chassis must be started with a full complement of PSUs, that is 10. 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.
A system should continue to run and allow a hotswap 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 may be necessary to reboot the chassis once the defective PSU has
been replaced.
1.
Check all:
boards
power supplies
leaf fan modules
spine fan modules
for proper insertion and seating before connecting the AC power cords.
2.
Insert all leafs that you plan to use, in the chassis.
3.
Insert thermal blanks in unused leaf slots to maintain balanced air flow.
4.
Tighten all mounting screws.
5.
Connect the power cords to the PSUs.
6.
Connect the power cords to grounded electrical outlets.
Mellanox Technologies
Do not power up the chassis with less than all PSUs installed.
Populate the chassis with the leafs before you power up the chassis.
A fully loaded IS5600 series switch system can draw 8 kW of power. Make sure that
the outlets and circuits will not be overloaded. Spread out the load over at least two or
three circuits, or a 3 phase supply.
