Installing the Expansion Module
Complete the steps in this chapter to install any of the following expansion
modules in an ARN:
• Ethernet
• Token Ring
• Tri-Serial
• Ethernet/Tri-Serial
• Token Ring/Tri-Serial
Although each expansion module type looks slightly different, you install them
identically onto the ARN base module, as follows:
1.
Open the ARN enclosure to access the component tray.
2.
Attach an antistatic wrist strap.
3.
Remove the expansion slot filler panel; or, if present, remove an existing
expansion module.
4.
Install the new expansion module on the ARN base module.
5.
Close the ARN.
6.
Connect network cabling.
7.
Proceed to software configuration tasks.
Caution:
Electrostatic discharge can damage hardware. You must wear the
antistatic strap whenever you remove, install, or handle printed circuit boards.
