Chapter 3
Installing the Cisco ASR 903 Router
Installing an RSP Module
To install an RSP module in the router chassis, perform the following steps:
Choose a slot for the module. Make sure that there is enough clearance to accommodate any equipment
Step 1
that will be connected to the ports on the module. If a blank module filler plate is installed in the slot in
which you plan to install the module, remove the plate by removing its 2 Phillips pan-head screws.
Fully open both the ejector levers on the new module, as shown in
Step 2
Caution
Step 3
Position the module in the slot. Make sure that you align the sides of the module with the guides on each
side of the slot, as shown in
Figure 3-14

Step 4
Carefully slide the module into the slot until the EMI gasket on the module makes contact with the
module in the adjacent slot and both the ejector levers have closed to approximately 45 degrees with
respect to the module faceplate.
Caution
Step 5
While pressing down, simultaneously close both the ejector levers to fully seat the module in the
backplane connector. The ejector levers are fully closed when they are flush with the module faceplate.
Step 6
Tighten the two captive installation screws on the module. The recommended maximum torque is 5.5
in.-lb (.62 N-m).
Note
OL-25178-04
To prevent ESD damage, handle modules by carrier edges only.

If the top slot already has an RSP module installed, and you install a second RSP module in
the slot below it, be careful not to damage the EMI gasket of the bottom RSP module against
the ejector levers of the top RSP during insertion.
Make sure that the ejector levers are fully closed before tightening the captive installation
screws.
