Guidelines for Line Card Removal and Installation

Guidelines for line card removal and installation include the following:
Caution Be careful to avoid damaging the electromagnetic interference (EMI) gasket that runs along the full
length of the card front panel edges. Damage to the EMI gasket can affect the ability of your system to
meet EMI requirements.
•
With OIR, notifying the software or resetting the power is not required. However, you have the option
Note
of using the shutdown command before removing a line card.
•
A card with an OIR count that exceeds 175 will generate a minor alarm against that slot. If the card OIR
Note
count exceeds 200, a major alarm is generated against that slot. Fan tray insertion counts are not checked
against a threshold.
See the Release Notes for Cisco ASR 9000 Series Aggregation Services Routers for Cisco IOS XR
Software Release 3.9.1 for information about CLI commands for obtaining and resetting card insertion
data. The CLI command indicates whether the particular chassis has the version of BPID that supports
the counting of the OIR.

Online insertion and removal (OIR) is supported, enabling you to remove and install line cards while
the router is operating. OIR is seamless to users on the network, maintains all routing information,
and ensures session preservation.
The backplane identification (BPID) board monitors OIR by counting the number of card insertions
for each slot and saving that information in non-volatile memory. OIR monitoring is done for all line
cards, the RSP, and the fan trays. A card insertion is determined by the CAN Bus Controller (CBC)
of the inserted card booting up and sending a CBC message which is intercepted by the BPID board.
Note that a CBC reset or power cycle on a card will also be interpreted as a card insertion.
