Installing a power module
CAUTION:
•
Provide a circuit breaker for each power module 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, phase, and frequency for the two grids must be the same.
• To avoid power module 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.
• To ensure good ventilation, install a blank filler panel over an empty slot.
The switch uses 1 + 1 power redundancy and supports AC and DC power input. For more information
about power modules, see "Appendix B FRUs and compatibility matrixes."
For the a switch that uses the PSR1400 or PSR2800, when the switch consumes less than 650 W power
and does not use PoE, use the following power modules:
• The PSR650C-12A or PSR650C-12D power module
• PWR-SPA power adapter and the PSR 650 power module
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.
