2 WLAN Installation Instructions

Enclosure Disassembly

The indicator enclosure must be opened to install the WLAN option card and antenna and to connect cables for

installed option card.

The 920i and 820i has no on/off switch. Before opening the unit, ensure the power cord is disconnected

from the power outlet.

Disconnect power to the indicator. Place the indicator face-down on an antistatic work mat. Remove the screws that

hold the backplate to the enclosure body, then lift the backplate away from the enclosure and set it aside.

Installing Option Cards

The general procedure for installing the WLAN option card is as follows:

Option cards are not hot-pluggable. Disconnect power to the 920i or 820i before installing the WLAN

option card.

1. Ensure that power has been disconnected to the indicator. Remove backplate as described in the previous

section.

2. Carefully align the WLAN option card onto a slot connector on the CPU board. Press down to seat the option

card in the CPU board connector.

3. Use the screws provided in the option kit to secure the other end of the option card to the threaded standoffs

on the CPU board.

4. Set up the WLAN configuration parameters as explained on page 4.

5. Make connections to the option card as required. Use cable ties to secure loose cables inside the enclosure as

shown in Figure 2. When installation and configuration is complete, reassemble the enclosure as shown on

page 9.

antenna once its been pushed through the hole.
