Installing a Small Module

Use the procedure in this section to install a Small Module in the Secure Router 4134. You can install Small Modules in slots 1, 2, 3, and 4.

ATTENTION

Slot 2 of the Secure Router 4134 supports only one port of any WAN data Small Module. If you install a 2-port Small Module in Slot 2, and use the Small Module for data connections, one port only is functional (port 1).

This limitation also applies to the 2-port T1/E1 and ISDN BRI Small Modules if they are configured for voice traffic: only port 2/1 is functional. This limitation does not apply to FXS or FXO voice modules.

If you are working with 2- or 4-port FXS or FXO Small Modules, ensure you read the safety messages related to the FXS and FXO interface modules. See “Foreign Exchange Station (FXS) Interface Modules” (page

17)and “Foreign Exchange Office (FXO) Interface Modules” (page 18).
