Guidelines for Removing and Installing a Line Card

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.

When installing a line card, always fully tighten both captive installation screws to ensure that the card

is correctly seated in the backplane connector. A card that is only partially seated in the backplane might
not operate properly, even if it boots.

Steps for OIR Line Card Removal and Insertion
Every card has a key mounted on the board that matches a corresponding slot on the chassis side
(top of each card slot). This key-slot mechanism prevents a card from being inserted into the wrong,
non-matching card slot. It also prevents a card from being inserted upside down. If you insert a card
into the wrong card slot or upside down, the key gets blocked against the chassis card guide and will
not slide though the slot. If the key is blocked, remove the card and find the correct card slot.
Online insertion and removal (OIR) is supported, enabling you to install a card while the FCC is
operating. OIR is seamless to users on the network, maintains all routing information, and ensures
session preservation. We recommend that you perform a graceful shutdown to shut down a fabric
card prior to removing it from the chassis. See
page 2-10.
When installing a line card, your must first push the OIR button on both the upper and lower ejectors
for the mechanical latch to be released.
The different cards in the chassis are attached to the chassis itself by a pair of ejector levers and
captive screws. The two ejector levers release the card from its midplane connector. The exact
locations of the ejector levers and captive screws can vary slightly from card to card, but are
generally in the same locations: on the upper and bottom ends of the faceplate.
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.
A card with an OIR count that exceeds 175 will generate a minor alarm against that slot. If the card
OIR count exceeds 200, a major alarm is generated against that slot. Fan tray insertion counts are
not checked against a threshold.
