How to Install a T1 Card in a Cisco 3800 Router

A T1 card enables you to connect a Cisco router to an external T1 network. You can insert the card into one of several expansion bays on a Cisco 3800 router. The expansion bays can handle either half-sized cards, such as the T1 card, or full-size cards, such as a switching module. Once installed, you can make adjustments to the T1 card configuration, if desired, using Cisco Command Line Interface (CLI).

  Pull the metal placeholder away from the router to remove it.

• 3

  Insert the T1 card into the now-empty slot.

• 4

  Tighten the two screws on each side of the T1 card to secure it to the router.
