Installing an option card

The printer has two connectors that support the following option cards:

•Hard disk with adapter card

•MarkNet N8000 series internal print server

•RS-232 Serial Interface Card

•Parallel 1284-B Interface Card

•Coax/Twinax Adapter for SCS

Warning: Option cards are easily damaged by static electricity. Touch something metal such as the printer frame before you touch an option card.

1Locate the card connectors on the system board.

2Remove the screw and the cover plate, and save them.

If you are installing a tall card, install it in connector 1. If you are installing two short cards on a model with multiple connectors, use connector 1 first, and then use connector 2.

3Unpack the card. Save the packaging materials.

4Align the connection points on the card with the connector on the system board, and push the card firmly into the system board connector.

5Insert the screw saved from the cover plate (or the extra screw shipped with the card).
