Removing An Interface Module; Hot-Swapping An Interface Module - Cisco ASR 903 Installation Manual

Installing the Cisco ASR 903 Router

chassis can deform or damage the handles.

Removing an Interface Module

Step 1
To remove an interface module, disconnect all the cables from each interface module.
Step 2 Loosen the locking thumbscrews on both sides of the interface module.
Step 3
Slide the interface module out of the router slot by pulling on the handles. If you are removing a blank filler plate, pull
the blank filler plate completely out of the router slot using the captive screws.

Hot-Swapping an Interface Module

The Cisco ASR 903 Router provides a feature that allows you to remove and replace an interface module
without powering down the router. This feature, called hot-swapping or OIR, allows you to remove and replace
a redundant module without disrupting router operation.
Use the following guidelines when performing an OIR on an IM:
• Allow at least 2 minutes for the system to reinitialize before inserting a new IM.
• Avoid inserting a new IM during bootup until the active and standby RSPs have reached an OK state.
• When inserting multiple IMs into the chassis, wait until each IM reaches an OK state before inserting
The following interface modules take around 60 to 70 seconds to reach OK state after a soft OIR is performed:
• Copper Combo IM—8-port Gigabit Ethernet (8X1GE) + 1-port 10 Gigabit Ethernet Interface
• SFP Combo IM—8-port Gigabit Ethernet (8X1GE) + 1-port 10 Gigabit Ethernet (1X10GE)
• 2-port 10 Gigabit Ethernet Interface Module(2X10GE) (PN:A900-IMA2Z). A900-IMA2Z IM supports
The A900-RSP1 RSP module does not support hot-swapping an interface module with another module of a
different type . For example, you cannot swap an SFP Gigabit Ethernet module with a copper Gigabit Ethernet
module without disrupting router operation.
