Maintaining the HRPSU
The HRPSU requires little maintenance. You should not open the HRPSU chassis.
If you have any problems, please call a qualified technician.
Replacing a Power Supply Module in the HRPSU
You can easily replace a power supply module in the HRPSU power rack if
necessary. The power on the HRPSU and the Network Devise(s) can stay on, and
the cables can be left in place for this procedure.
Figure 3-1
shows a power supply module with the latch lifted.
Replace a power supply module using the following steps:
1.
Turn off the power supply switch on the front of the HRPSU module to be
replaced.
2.
Lift the latch on the front of the module, and using it as a handle, pull the
module straight out of the slot. When the module is removed, the safety
door falls shut and locks into place.
3.
Lift the latch of the new power supply module and slide the module
straight into the slot between the side rails. The flange on the back of the
module releases the safety door as the module pushes the door up.
4.
When the module cannot go any farther, it is connected to the backplane.
Push the latch down firmly to lock the module in place.
Danger:
Due to high energy hazards, only qualified service personnel are
permitted to install or replace components inside the HRPSU chassis.
