Cisco ASR 903 Installation Guide

10 Gigabit Ethernet interface modules on the A900-RSP1 modules and A900-RSP2A-64 module are not
supported in slots 4 and 5.
Note
Close all unused RJ-45, SFP, XFP, and QSFP ports on the interface module using the appropriate dust caps to
prevent dust from accumulating inside the cage. For information on dust caps, see Installing Dust Caps.
Note
Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the
chassis can deform or damage the handles.
Caution
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 next IM.
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
Module(1X10GE) (PN:A900-IMA8T1Z)
• SFP Combo IM—8-port Gigabit Ethernet (8X1GE) + 1-port 10 Gigabit Ethernet (1X10GE)
(PN:A900-IMA8S1Z)
• 2-port 10 Gigabit Ethernet Interface Module(2X10GE) (PN:A900-IMA2Z). A900-IMA2Z IM supports
SFP+ and XFP on ports 0 and 1. Either SFP+ or XFP can be connected on each port. If both are connected
on the same port, the port will go down.
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.
• The router does not support swapping of the TDM interface modules to Gigabit Ethernet modules on the
Cisco ASR 900 Series Router and vice-versa.
• If the TDM interface module is swapped with the Gigabit Ethernet module in the same slot or vice-versa,
the router must be reloaded.
