Enclosure Disassembly
The indicator enclosure must be opened to install the WLAN option card and antenna, and to connect the wiring.
WARNING Before opening the unit, ensure the power cord is disconnected from the power source.
1. Disconnect power to the indicator
2. Place the indicator face-down on an anti-static work mat.
3. Remove the screws that hold the backplate to the enclosure body,
4. Lift the backplate away from the enclosure and set it aside.
Installing the Option Card
Installing the WLAN card as follows:
1. If installed, remove the plastic cover over the power supply (AC units).
2. Remove the two-wire cable that connects the power supply to the CPU board (discard).
Note
If this is a CLS-420 installation, cut the red and black wires that lead to the 10-position connector on the
bottom of the enclosure as close as possible to the tap-and-run connectors. These two wires will later be
attached to the option card. These wires are shown in Figure 3.
