II. Installing a power module
Install a power module in the opposite order you remove it:
1) Put on an ESD-preventive wrist strap and take a new power module out of its
package. Check that the input mode of the power module is as required.
2) Grasp the handle of the module with one hand and hold the module bottom with
the other. Gently push the power module along the guide rails into the chassis until
it has firm contact with the connector on the backplane.
Caution:
Be sure not to insert the power module with its front panel upside down.
Follow the forward inertia of the power module when inserting it into the chassis to
ensure that the power module has firm contact with the connector on backplane.
To prevent damage to the power module and the connection terminals on the
backplane, make sure to pull the module out first in case of any misalignment, and then
push it in again.
3)
Tighten the captive screws with a screwdriver to secure the power module to the
chassis.
Caution:
If the captive screws cannot be tightened, check whether the power module is properly
installed.
