EMULEX MODEL 375 SAN STORAGE SWITCH	CHAPTER 2: SWITCH INSTALLATION
USER’S GUIDE

POWER SUPPLY/FAN MODULE REPLACEMENT

The Emulex® Model 375 SAN Storage Switch has hot-swappable power supply/fan modules for high availability. A power supply/fan module consists of an individual power supply and a fan bank consisting of three fans.

The switch can run on one functioning power supply/fan module indefinitely, as long as the faulty power supply/fan module remains installed in the switch and there are at least two fans operational in each module’s fan bank. If the power supply/fan module is removed from the switch, the switch will continue to operate normally for approximately 20-30 minutes. Non-functional modules should be immediately replaced to maintain high availability.

Note: Keeping spare power supply/fan modules (Part Number 601319) in stock is highly recommended. Contact a sales representative for further information.

To remove an old power supply/fan module:

1.Have the new power supply/fan module close to the switch for quick insertion. (This step ensures that the procedure takes no longer than necessary—the switch can only operate with one power supply/fan module installed for approximately 20-30 minutes.)

2.Unplug the power cord from the faulty module’s power receptacle.

Note: The alternate power supply/fan module should remain powered on while the faulty module is removed and replaced to guarantee switch availability.

3.Slide the safety latch over the power receptacle to expose the thumb screw.

4.Loosen the two thumb screws. No tools are required.

5.Pull the unscrewed power supply/fan module out of the switch’s module bay using the module’s handle.

WARNING

To avoid an electrical hazard, never apply power to the power supply/fan module while the module is

removed from the switch.

To insert a new power supply/fan module:

1.Align the power supply/fan module with the module bay opening. Ensure that the warning label is facing upwards on the module.

2.Carefully slide the module into the opening. Ensure that the module is seated firmly in the module bay (the module should be flush with the switch’s face).

3.Tighten the two thumb screws. No tools are required.

Note: When using a screwdriver to tighten the thumb screws, ensure that the thumb screws are secure but not overtightened. Overtightening the thumb screws may damage the screws or the module.

4.Slide the safety latch over the thumb screw (uncovering the power receptacle).

5.Plug the power cord into the module’s module power receptacle.
