Disconnecting Power

To power down the repeater, disconnect the power cord from the non- switched, grounded power outlet on the wall, power strip, or grounded extension cord. The power cord is not a TUV-tested disconnect. Therefore do not power down the repeater by disconnecting the power cord connector from the back of the repeater.

Replacing the Power Supply

The power supply's modular design makes the supply easy to replace. If power supply replacement is necessary, follow the instructions under “Installing a Redundant Power Supply Module” in the next section.

Supply Module

The repeater comes with a pre-installed, 90-watt power supply module (PWR A). You can install an optional redundant power supply module (PWR B) for backup power. Contact your authorized Compaq reseller for information about ordering an additional power supply module or a replacement.

Follow these steps to install a redundant power supply module.

NOTE: You can install the redundant power supply module while the main power supply module is powered on.

1.Remove the two screws from the PWR B cover plate and remove the plate. Be sure you keep the cover plate and screws in case you need them for future use.

2.Carefully insert the power supply module into the opening until its 10- pin connector engages with the internal power connector and the face of the module is flush with the repeater's back panel.

3.Secure the power supply by tightening its two spring screws.
