Power Connections

The chassis includes integrated hot-swap power supplies which support up to 10 load-

sharing 1000W supply units. The slots for the power supply units (PSUs) are on the spine

side. The left side has odd numbered PSUs and the right side has even numbered PSUs.

Each PSU has a dedicated AC inlet. This design enables the optional use of separate main

and backup AC feeds. The input voltage is Autorange, 100-240 VAC, 50Hz or 60Hz. The

output voltage for the PSUs is 48V. The power cords are standard 3-wire AC power cords

including a safety ground.

Before starting any procedure on the IS5600 series switch system put an ESD prevention

wrist strap on your wrist and connect to the IS5600 series chassis.

4.1

Plug in the power cords to the PSUs.

Plug the other end of the power cord into a grounded outlets.

The Chassis must be started a full compliment of possible 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.

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.

The power system will divide the current consumption by the number of working PSUs.

Should one of the PSUs fail, the total current consumption will then be divided by the

remaining working PSUs. When the failed PSU is hot swapped the new PSU will ramp up

and pass its share of current, so that the total current is always divided by the number of

working PSUs.

Make sure that the power cords are compatible with your outlets. Power cords for dif-

ferent countries can be ordered from Mellanox. See the user manual appendix for

ordering part numbers for power cords.

A fully loaded IS5600 switch system can draw 8 kW (~67A @ 120V or 34A@240V)

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 use a 3 phase circuit.
