Installing a Switch
Module
To install a switch module in the CoreBuilder 7000 family ATM switch
chassis:
1
Remove the new card from its antistatic bag.
2
Orient the card so its labelling is upright and make sure the inject handles
are in the outward position.
3
Insert the card into the chassis by placing it between the guides of the
selected slot and sliding the card until it stops.
4
Grab both inject handles and push them inward. This locks the card into
the chassis. You may have to apply considerable pressure to the handles.
An audible “click” indicates that the connectors have engaged.
5
Tighten the card’s securing screws. You are now ready to connect cables
to the appropriate ports.
Replacing a Switch
Module
To hot-swap the switch module:
1
Disconnect the cables from the card's ports. Ensure that there is a record
of where the cables are attached so that you can correctly re-connect
them to the new card.
2
Loosen the screws at the extreme right and left of the card, near the
insert/eject handles.
3
Grasp the insert/eject handles of the card you want to replace and push
them outward. This ejects the card. You may have to apply considerable
force to the handles. You will hear a “click” to indicate that the
connections have separated, and the card will slide slightly forward out of
the CoreBuilder chassis.
4
Remove the new card from its antistatic bag. Place the old card in the
antistatic bag and set it aside in a safe place.
5
Orient the card so its labelling is upright and make sure the inject handles
are in the outward position.
6
Insert the card into the chassis by placing it between the guides of the
selected slot and sliding the card until it stops.
7
Grab both inject handles and push them inward. This locks the card into
the chassis. You may have to apply considerable pressure to the handles.
An audible “click” indicates that the connectors have engaged. Verify
that the card has been properly installed by observing its LEDs.
8
Tighten the card’s securing screws.
