RSP Installation
Follow these steps on handling an RSP module in the Cisco ASR 903 Router:
Installing an RSP Module
To install an RSP module in the router chassis, perform the following steps:
Step 1 Choose a slot for the module. Make sure that there is enough clearance to accommodate any equipment 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.
Step 2 Fully open both the ejector levers on the new module, as shown in the figure below.
To prevent ESD damage, handle modules by carrier edges only.
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 the figure below .
