Installing a power module
CAUTION:
•
Provide a circuit breaker for each power supply and make sure the circuit breaker is off before
installation.
• Do not install power modules of different models on the same switch.
• For dual-grid input, the input voltage and frequency for the two grids must the same.
• To avoid power supply damage or bodily injury, support the bottom of a power module instead of
holding its handle for power module movement.
• Before installing a power module, make sure the power module is switched off.
• Make sure the power of the power module can satisfy the requirements of the switch.
The switch uses 1 + 1 power redundancy and supports AC and DC power input. For more information
about optional power modules, see "Appendix B Pluggable module ordering guide."
For a switch using high-power power modules such as PSR1400/PSR2800, you can supply power to the
switch by using the PWR-SPA power adapter and the PSR 650 power module when the system power
consumption of the switch is no higher than 650 W. For more information about the power adapter, see
the H3C PWR-SPA Power Module Adapter User Manual.
If you select a power adapter, install it to the chassis, and then install a power module to the power
adapter. The installation procedures are the same as installing the power module to the chassis.
Installing a power module
CAUTION:
If the captive screws cannot be fastened, verify that the power module is correctly installed.
1. Wear an ESD wrist strap and make sure it has a good skin contact and is well grounded. For more
information, see "
Attaching an ESD wrist strap ."
2. As shown in callout 1 on Figure 21 , remove the blank filler (if any) from the slot to be used. Keep
the blank filler secure for future use.
3. Unpack the power module, and verify that the power module model is correct.
4. Be sure to insert the power module with its upside up. Grasp the handle of the module with one
hand and support the module bottom with the other.
5. As shown in callout 2 on Figure 21 , gently push the power module along the guide rails into the
slot until it has firm contact with the slot.
6. As shown in callout 3 on Figure 21 , use a Phillips screwdriver to fasten the captive screws on the
power module to secure the power module into the chassis.
