4.8.6 Installing an FCU_E2U in the EXT-2U

The EXT-2U platform must have one Fan Control module (FCU_E2U) installed in the FCU slot, and is shipped
with the module already installed. The following procedure therefore describes replacing the module.
This procedure is also applicable for replacing an operating FCU_E2U. To perform the replacement in the
shortest time, prepare the replacement FCU_E2U in advance by taking it out of its package and placing it
near the operating unit.
C
AUTION: To avoid traffic hit in an operating system, don't turn it off while replacing an
FCU_E2U. The system can operate without a fan unit for up to 4 minutes. Perform the
replacement in this time.
To install an FCU_E2U in the EXT-2U:
1. Check that the module has not been physically damaged during shipment, and that the antistatic
protection bag of the original packaging is sealed.
2. Remove the module from its antistatic protection packaging and perform a visual inspection to detect
damage during shipping. Report any problems.
3. Hold the FCU_E2U module extractor and insert the rear end of the power module into the card
guides.
4. Push the module in until the panel at the front of the module is flush with the front of the EXT-2U
platform. If resistance is felt before the connectors are flush, pull the module out and repeat the
procedure.
5. Secure the module in place by tightening the two screws with a screwdriver.

The EXT-2U is shipped with its Eslots covered by blank panels. Remove the corresponding cover to install an
extension card. Extension cards are installed according to the site installation plan
