3. Gently pull the PSU module towards you to unseat it from the backplane and to disengage the PSU module
from the chassis.
4. Pull the PSU module free from the chassis and set it on a static-free surface.
Installing a new PSU Module into the Ultripower Chassis
Once you have removed the failed PSU module or the blank module plate from the Ultripower chassis, you can
install the new PSU module into the unpopulated slot. The following procedure is applicable to any PSU Module
slot.
To install a new PSU module into the chassis
1. Align the new PSU module into the slot inside the chassis.
2. Gently slide the new PSU module into the slot until the module is fully seated. You will feel the back connector
of the module engaged with its connector inside the chassis.
3. Fully tighten both retaining bolts. These bolts secure the PSU module to the chassis from the interior, ensuring
proper contacts between the PSU module and the Ultripower backplane.
Caution
— Tightening the bolts separately may damage the PSU module. Ensure the bolts are equally
tightened and at the same time.
