Replacing a power supply
The DC04 SAN Director can continue operating during the replacement if at least one power
supply continues operating. The replacement procedure for each power supply takes less than five
minutes. A power supply unit or filler panel is required for the power supply replacement.

Removing a power supply
CAUTION: Wear a grounded ESD strap when handling DC04 SAN Director components. The
DC04 SAN Director chassis provides a grounding connection above the power connectors. Also,
store ESD-sensitive components in antistatic packaging.
To remove a power supply:
1. If the DC04 SAN Director is not operating during the replacement procedure, go to step 2.
If the DC04 SAN Director is going to continue operating during the replacement, observe the
power LEDs to verify that the minimum number of power supplies is functioning. A
fully-populated DC04 SAN Director requires a minimum of one power supply slot at all times
to ensure power to the DC04 SAN Director.
2. Turn off the power switch.
3. Remove the power cord.
4. Loosen the thumb screw.
5. Grasp the handle and pull, sliding the power supply from the chassis and supporting the
power supply from beneath as you remove it (see Figure 41 (page 78)).
6. If you are not replacing the power supply, insert a filler panel into the slot.
Installing a power supply
To install a power supply:
1. Remove the filler panel, if necessary.
2. Insert the power supply into the slot and push the handle up. Verify that the power supply is
seated by gently pulling on the handle (see Figure 41 (page 78)).
3. Tighten the thumb screw.
4. Replace the power cord.
5. Turn on the power switch.
