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.
