Installing the power supply system
CAUTION:
•
In case of dual grid inputs, make sure the amplitude, phase, and frequency of the input voltage of
the two grids are the same.
•
Provide a circuit breaker for each power module.
•
For good ventilation of the switch, make sure a filler panel is installed in each unused slot.
•
Do not install a power module adapter and a 3 RU power module on the same switch.
•
Make sure the power configurations are the same on the two power module slots. To use power
module adapters, make sure the two power module slots have the same power module adapter
and power module configurations.
The switch uses 1+1 power module redundancy and supports dual grid inputs. The switch supports
AC and DC power. For information about the power modules available for the switch, see
H3C
S7500X-G Switch Series Hardware Information and Specification .
For a switch that uses high-capacity power modules, for example, the PSR1400-12D1 power
modules, you can use the following configurations for power supply when the system power
consumption is small:
•
Power module adapters and PSR650-A/PSR650-D power modules (not recommended) when
the switch consumes less than 650 W.
•
LSQM1PWRSPB (0231A5X0) power module adapters and
PSR650-A/PSR650-D/PSR1200-A/PSR1200-D power modules if you are to install more than
two power modules in the switch.
To use a power module adapter, install the power module adapter in the chassis first, and then install
power modules in the power module adapter.
Installing a power module adapter
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
For more information, see "
Attaching an ESD wrist strap ."
2. Unpack the power module adapter.
3. Holding the adapter handle with one hand and supporting the adapter bottom with the other,
slide the adapter all the way into the chassis along the guide rails. Make sure the adapter is
firmly seated in the chassis and has good contact with the backplane connectors.
To avoid damaging the power module adapter and the backplane connectors, remove the
adapter, realign it with the chassis, and insert it again in case of misalignment.
4. Use a Phillips screwdriver to fasten the captive screws on the adapter to secure the adapter in
the chassis.
If you cannot fasten the captive screws tightly, check the adapter installation.
