Interface Module Installation

3. Initializes the newly inserted module. In addition, the system notes any removed modules and places those
modules in the administratively shutdown state.
4. Places any previously configured interfaces on the module back to the state they were in when they were
removed. Any newly inserted interfaces are put in the administratively shutdown state as if they were
present (but unconfigured) at boot time. If you insert the same type of module into a slot, its ports are
configured and brought online up to the port count of the original module.
The router runs diagnostic tests on any new interfaces and the test results indicate the following:
• If the tests pass, the router is operating normally.
• If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.
• If the diagnostic tests fail, the router stops operating, which usually indicates that the new module has a

The following sections describe the various tasks of associated with interface module installation on the Cisco
ASR 903 Router:

Installing an Interface Module

Step 1 Before inserting an interface module, make sure that the chassis is grounded.
Step 2 To insert the interface module, carefully align the edges of the interface module between the upper and lower edges of
the router slot.
Step 3 Carefully slide the interface module into the router slot until the interface module makes contact with the backplane. The
figure below shows how to install the interface module.

Step 4 Tighten the locking thumbscrews on both sides of the interface module. The recommended maximum torque is 5.5 in.-lb
(.62 N-m).
Step 5 Connect all the cables to each interface module.
Close all unused SFP ports using SFP dust caps to prevent dust from accumulating inside the cage. The dust
