Checking the rack switch settings

Procedure

  1. Verify the setting of the following switches on Rack-1.
    Table 1. Switch settings and locations
    Switch Setting Location Figure reference
    Battery enclosure circuit breakers CB0 and CB1. On (up) On each battery assembly (rear of rack)  4  in Figure 1
    UEPO red switch Off (in at bottom) Rack operator panel (front of rack)
    Note: Press the recessed switch towards the bottom. It will appear flat when off.

  2. Continue verifying the settings of the following switches on Rack-1.
    Table 2. Switch settings and locations
    Switch Setting Location Figure reference
    Primary power supply circuit breaker CB00 Off (down) On each PPS, on the AC input power module (rear of rack)  3  in Figure 1
    Primary power supply sequencer module enable/disable switches Enabled (up) Three switches on each sequencer module (rear of rack)  1  in Figure 3
    PPS 5/12 V DDM power module enable/disable switches Enabled (up) Two switches on each 5/12 V DDM power module (rear of rack)  1  in Figure 4
    Enable/disable switch on the PPS booster power module (Power Line Disturbance PLD module) Enabled (up) Optional module, only present for PLD feature. One on each PPS on booster power module (rear of rack) Callout label 1 in Figure 5.

    The enable disable switches for the primary power supply sequencer module are displayed in Figure 3.

  3. Do you have additional storage expansion racks?
  4. Verify the setting of the following switches on each expansion rack. Each rack has:
    • One UEPO switch
    • Two PPSs
    • Zero to three battery enclosures
    Table 3. Switch settings and locations for storage expansion racks
    Switch Setting Location Figure reference
    UEPO red switch Off (down) Rack operator panel (front of rack)
    Note: Press the recessed switch towards the bottom. It will appear flat when off.
