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 of the module.
Replacing a 4-Port
Interface Module
To replace individual daughter cards, or to replace the entire interface
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 If you are replacing the entire interface card, remove the new card from
its antistatic bag. Place the old card in the antistatic bag and set it aside in
a safe place.
Fan Tray
To replace the fan tray:
1 Loosen the screws at the top and bottom of the fan tray.
2 Pull the fan tray out of the chassis.
3 Remove the new fan tray from its antistatic bag. Place the old fan tray in
the antistatic bag and set it aside in a safe place.
4 Orient the fan tray so its labelling is upright.
5 Insert the new fan tray into the chassis by placing it between the guides
of the slot and sliding it until it stops.
6 Tighten the fan tray’s securing screws.
