•
Handle a card by its ejector levers, when applicable, or its metal carrier only; avoid touching the board
or connector pins (see the
Guidelines for Installing and Removing a Card, on page 52
).
•
Place a removed card board-side-up on an antistatic surface or in a static-shielding bag. If you plan to
return the component to the factory, immediately place it in a static-shielding bag.
•
Avoid contact between a card and clothing. The wrist strap protects the board from only ESD voltage
on the body; ESD voltage on clothing can still cause damage.
•
Be careful not to lay any tools on the aluminum honeycomb panel, or insert your fingers into the panel.
Guidelines for Installing and Removing a Card
•
Online (in-service) insertion and removal (OIR) is supported, enabling you to remove and install cards
while the chassis is operating. OIR is seamless to users on the network, maintains all routing information,
and ensures session preservation. You do not need to notify the software or reset the power. You have
the option of using the Cisco IOS XR
shutdown
command before removing a card.
OIR removes power to a specific slot before the card is replaced. The power remains on for all other card
slots.
Note
•
The different cards in the Cisco NCS 4016 chassis are all attached to the chassis itself using a pair of
ejector levers and captive screws. The two ejector levers release the card from its backplane connector.
The exact locations of the ejector levers and captive screws can vary slightly from card to card, but they
are generally in the same locations: on the upper and bottom ends of the faceplate.
•
When you remove a card, press the OIR buttons before using the ejector levers to ensure that the connector
pins disconnect from the backplane in the sequence expected by the chassis.
•
The correct card orientation is shown by the eject symbol on the OIR buttons. The symbol must be
oriented upward for cards in the top row, and downward for cards in the bottom row.
•
Every FC, LC, and RP 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. When a
card is inserted into the wrong card slot or upside down, the key will get blocked against the chassis
card guide and not slide though the slot. When the key gets blocked, remove the card and find the correct
card slot.
RP card faceplates are labeled with the square symbol. Card slots on the chassis for RP cards are also
labeled with the square symbol. FC faceplates are labeled with the plus symbol. Card slots on the chassis
for FCs are also labeled with the plus symbol.
Note
•
The chassis is shipped with all card slots containing filler cards to help maintain chassis stiffness and
prevent any damage to the chassis during shipment.
•
Any unused card slots that are uncovered would allow air used for chassis cooling to escape. Therefore,
to ensure proper air flow and maintain system EMC and safety compliance, any unused LC slots must
contain filler cards, and all FC and RP cards must remain installed in their card slots.
