The 

Spacevars
0series2
chassis configured for AC power is is shipped with two dual redundant AC power supplies. Dual redundancy means the power supplies are hot-swappable. In other words, you can replace a power supply without powering down the 
Spacevars
0series2
platform (provided that the redundant Power Supply is operational).

The figure AC Power Supply below depicts a dual redundant configuration. 

The AC power supply Customer Replaceable Unit (CRU) Ribbon Part Number is 451-01043 and the product codes are:

  • SBC-7000-PSUAC
  • SBC-7000-PSUAC-SPARE

titleImportant
Before replacing a Power Supply in a redundant power supply configuration, verify the status of the redundant power supply. The Power OK (POK) LED status must be solid green. Removing the Power Supply when the redundant supply does not show a solid green status, may cause the system to power down. Contact

  • Install the replacement AC Power Supply to the 

    Spacevars
    0series2
    chassis by sliding it forward until you hear the latch click in place.
    The AC Power Supply has two LEDs per each AC Line, OK and Power OK (POK).

  • The AC Line OK is turned on when the power supply is connected to the AC power source to verify the existence of the AC power. The Power OK (POK) indicates that the power supply is enabled and it is supplying the 

    Spacevars
    0series2
    with power.

  • Observe that the POK green LED on the newly-inserted Power Supply is solid green. It takes maximum 1 minute for the Power Supply to turn on.

  • From the application, ensure that no Power Supply alarms are generated.
