Note: The Cisco 1600 series is not capable of supporting the WIC−2A/S due to the lack of Serial
Communications Controllers.

The NM−1E2W, NM−1E1R2W, and NM−2E2W network modules do not have enough performance to
support the WIC−2A/S.

The WIC−2A/S can be damaged by excessive electrostatic discharge. You can minimize this electrostatic
discharge in these ways:

Use shielded cable end−to−end.

• 

Use a data surge protector that protects against surges over +/− 18v.

• 

Use an optical isolator (best protection).

• 

The default setting for this module is synchronous. To configure the module for asynchronous
communication, issue the physical−layer async command. Here is a section of an asynchronous
configuration:

Configuration

maui−soho−01(config)#interface Serial 2/0

maui−soho−01(config−if)#physical−layer async

maui−soho−01(config−if)#ip add 10.0.0.1 255.255.255.0

maui−soho−01(config−if)#async mode interactive

maui−soho−01(config−if)#async default routing
