Continuous operation during replacement

Important

The power supply module replacement time must be as short as possible because the Gateway E-842R enclosure is designed to operate with two power supply modules installed.

Important

The fans within the cooling module are not user replaceable. In the event of a cooling fan failure, the complete cooling module must be replaced.

Depending on how your Gateway E-842R enclosure is set up, you can normally replace a failed disk unit without interrupting the use of the system.

In addition, each enclosure contains two power supply modules, either of which can maintain power and cooling to the subsystem while the other is replaced.

Ops panel

Important

The Ops panel is an integral part of the enclosure assembly and can only be replaced with a replacement enclosure. The enclosure should only be replaced by trained personnel.

Replacing a module

Caution

When replacing a module, never leave an empty space in the rear of the enclosure.

Obtain a replacement before removing the problem module.

Caution

Observe all conventional ESD precautions when handling modules and components.

Avoid contact with such things as backplane components and module connectors.

See “Getting Started” on page 15 for information on the initial installation of the plug-in modules in your Gateway E-842R enclosure.

Power supply modules

Caution

The Gateway E-842R enclosure must only be operated with two power supply modules installed.

AC Power supply module

Caution

Do not remove the faulty power supply module unless you have a replacement unit of the correct type ready for insertion. The system must not be operated without both power supply modules in place.

Removing a power supply module

You can continue working while replacing the faulty module because there should always be two power supply modules in place.
