3.2 Preparing the Bridge for Servicing
Follow these steps before performing any servicing procedures on the bridge.
1. Remove power to the bridge by unplugging the power cord from the ac outlet
and then from the bridge, as shown in Figure 3–2.
2. Disconnect the interface cable(s) from the NI module. Note that the AUI
cable connector locks into place with a slide latch (see Figure 3–2). To re-
move the AUI cable, push the slide latch to the right to unlock the connector.
To remove the ThinWire cable, push in and rotate the connector a quarter
turn.
3. Remove the fiber optic cable(s) from the FI module. If you have a protective
cover available, place it on the fiber optic connector to protect it against dust.
