Cards other than MIO/UMIO that are in either the Active or Standby modes should be halted prior to removal.
Halting these cards places them into the "offline" mode. In this mode, the card is unusable for session processing
as either an active or redundant component. If a card in the active mode is halted, its tasks, processes, or
network connections will be migrated or switched to a redundant component prior to entering the offline
mode.
Initiate a manual card migration by entering the Exec mode card halt slot# command.
Verify that the migration was successful by entering the Exec mode show card table command. Check the
entry in the Oper State column next to the card that was just halted. Its state should be Offline. If the card was
in active mode prior to the execution of this command, the state of the redundant component associated with
it should now be Active.
All status LEDs on the halted card should be OFF when a card is offline and ready to be replaced.
Attempting to replace a circuit card that has not been taken offline may result in spurious error messages
and unexpected behavior that may initiate reload of other cards.
Caution
For additional information about the above commands and procedures, refer to the Command Line Interface
Reference and the Troubleshooting section of the System Administration Guide.
Replacing a Failed Card
This section describes how to remove and replace a failed circuit card.
Circuit cards can be replaced while the ASR 5500 is operating.Important
The optical SFP+ interfaces on the MIO/UMIO comply with the limits for Class 1 laser devices for IEC825,
EN60825, and 21CFR1040 specifications.
Important
If the chassis in which the card is to be replaced interfaces via SRP with a peer chassis for Interchassis
System Recovery (ICSR), the chassis to receive the replacement card must be placed in SRP Standby.
Verify its current state by running the Exec mode show srp info command. Refer to the System
Administration Guide for instructions.
Important
During installation, maintenance, and/or removal, wear a grounding wrist strap connected to the ASR
5500 chassis to avoid ESD damage to the components. Failure to do so could result in damage to sensitive
electronic components and potentially void your warranty.
