To power up a 2U expansion enclosure, install the power cords and check the
status LEDs on installed canisters.
About this task
Use either the rack PDU power cords that are supplied with the expansion enclosure, or the
country-specific power cords bought as an option. Two cords are required.
Procedure
To power on the system, complete the following steps.
- Power on all 2U expansion enclosures by connecting both power supply units of the enclosure to
their power sources, by using the supplied power cables. If the power sources have circuit breakers or switches, ensure that they are turned on. The
enclosure does not have power switches. Repeat this step for each expansion enclosure in the
system.
Note: Each enclosure has two power supply units. To provide power
failure redundancy, connect the two power cords to separate power circuits.
- Check the light-emitting diodes (LEDs) on each 2U expansion canister (see Figure 1).
Figure 1. LEDS on 2U expansion canisters
The canister is ready with no critical errors when Power is illuminated,
Status is illuminated, and Fault is off. If a canister is not ready, refer to
Procedure: Understanding the system status using the LEDs.
- Wait for all 2U expansion canisters to finish powering on.
- Power on the control enclosure by connecting both power supply units of the enclosure to their
power sources, by using the supplied power cables. If the power sources have circuit breakers or switches, ensure that they are turned on. The
enclosure does not have power switches.
Note: Each enclosure has two power supply
units. To provide power failure redundancy, connect the two power cords to separate power
circuits.
- Check the LEDs on each node canister in the control enclosure (see Figure 2).
