Removing and Installing the DC-Input Power Supplies
Chapter 4
Removal and Replacement Procedures
Warning
When installing or replacing the unit, the ground connection must always be made first and
disconnected last. Statement 1046
Caution
Step 18
Step 19
To prevent a short circuit or shock hazard after wiring the DC-input power supply, reinstall the terminal
block covers.
After you confirm that all installation steps are completed correctly, remove any safety flags, lockout
devices, or adhesive tape from the source DC circuit breakers, and energize the source DC circuits to the
power supplies.
Turn the power switch to the On (|) position on the power supply. Turning on the power switch also
engages a pawl that locks the power supply in the chassis.
Verify the power supply operation by ensuring that the power supply front panel LEDs are in the
following states:
• INPUT OK 1 LED—If you have source DC cables attached to the VE-1 pair of power supply inputs,
verify that the LED is green. If source DC cables are attached and the LED is not lit, source DC
might not be on or the source DC voltage is less than or equal to –33 VDC. If the source DC voltage
is between –33 VDC and –40.5 VDC, the LED can be either on, off, or flashing.
• INPUT OK 2 LED—If you have source DC cables attached to the VE-2 pair of power supply inputs,
verify that the LED is green. If source DC cables are attached and the LED is not lit, source DC
might not be on or the source DC voltage is less than or equal to –33 VDC. If the source DC voltage
is between –33 VDC and –40.5 VDC, the LED can be either on, off, or flashing.
• INPUT OK 3 LED—If you have source DC cables attached to the VE-3 pair of power supply inputs,
verify that the LED is green. If source DC cables are attached and the LED is not lit, source DC
might not be on or the source DC voltage is less than or equal to –33 VDC. If the source DC voltage
is between –33 VDC and –40.5 VDC, the LED can be either on, off, or flashing.
• FAN OK LED is green.
• OUTPUT FAIL LED is not lit.
If the LEDs indicate a power problem, see the “Identifying Startup Problems” section on page E-3.
Removing and Installing a 6000 W DC-Input Power Supply
This section covers the power supply removal and installation procedures for the 6000 W DC-input
power supply (PWR-6000-DC) and is divided into the following topics:
• Required Tools, page 4-59
• Removing a 6000 W DC-Input Power Supply, page 4-59
• Installing a 6000 W DC-Input Power Supply, page 4-64
Note
For proper 6000 W DC-input redundant power configurations, all of the source DC for one 6000 W
DC-input power supply must come from the same battery system (A feed); all of the source DC for the
other 6000 W DC-input power supply must come from another battery system (B feed).
