Installing the Power Supplies
Install each power supply as follows:
1. Align the metallic support plate of the first power supply vertically with the card guides in the
chassis.
2. Press upward on the power supply latch located on the front bottom of the assembly and
carefully insert the power supply into the chassis until the connectors on the power supply make
contact with the backplane connectors.
3. Firmly, push the power supply unit into the chassis until the power supply latch engages the
corresponding slot in the chassis.
The latch on the power supply acts as a retainer latch and a power ON/OFF
switch for the unit.
4. Make sure the latch is fully engaged (down and secured/mated into the corresponding slot in the
chassis) to enable (energize) the power supply.
Refer to the appropriate chassis location and allocation descriptions for the
total amount of power supplies that are required for proper operation.
Each slot must have either a power supply or a blank installed. Refer to the
specific section in the manual for the correct slots for your configuration.
If applicable, repeat the above Steps for the remaining power supplies.
11.1.6
Removing the Power Supplies
To remove a power supply, follow these steps (you may remove power supplies while the Cheetah
system is operational [energized], which is called hot-swapping):
Make sure you will still have the minimum number of power supplies
installed before removing power supplies. The minimum number depends
on your configuration. If you only have the minimum number of power
supplies installed and you must remove one, de-energize the unit first.
1. Open the Cheetah front cover.
When the latch on the power supply is moved to the full-upward position,
the power supply is switched off and is freed from the retaining slot in the
chassis.
2. Push and hold the latch on the lower front of the power supply in the full-upward position.
