IBM TotalStorage FAStT600 Fibre Channel Storage Server: Installation and User's Guide
Use the following procedure to replace a hot-swap fan:
1. Check the LEDs on the back of the storage server.
2. If the amber Fault LED is on, remove the fan CRU that has failed.
a. Slide the latch to unlock the fan CRU.
b. Use the handle (black knob) to pull the fan from the storage server. See
Figure 62.
Figure 62. Removing a fan
3. Install the new fan unit.
a. Place the fan CRU in front of the fan slot.
b. Hold the latch open, and slide the fan all the way into the slot. If the fan
does not go into the bay, rotate it 180°. Ensure that the latch is on the side
closest to the center of the storage server.
c. Release the latch. If the lever remains open, pull back on the fan slightly,
and then push it in again until the latch snaps into place.
4. Check the LEDs.
The Fault LEDs turn off after a few seconds. If they remain on, see
"Troubleshooting" on page 98.
The storage server power system consists of two power supply CRUs.
Exception: The FAStT600 single-controller storage server (Model 6LU/6LX) has
only one power supply CRU. Therefore, you cannot hot swap the power supply.
The power supply CRUs provide power to the internal components by converting
incoming ac voltage to dc voltage. One power supply CRU can maintain electrical
power to the unit if the other power supply is turned off or malfunctions. The power
supply CRUs are interchangeable (by reversing the locking levers).
Each power supply CRU has a built-in sensor that detects the following conditions:
v Over-voltage
v Over-current
v Overheated power supply
