Installing NBX 100
NCP and Other
Cards
Although the chassis has seven blank faceplate covers, it holds six cards.
The space behind the top faceplate cover is for future expansion of the
NCP. You cannot install a card in this top space — it does not have guide
slots or a backplane connector.
You can install the following cards in the NBX 100 chassis:
■
NCP
■
4-Port Analog Line card
■
Digital Line card (T1 or E1)
■
8-Port Hub card
■
4-Port Analog Terminal Adapter card
This section provides generic instructions for installing cards. Subsequent
sections and chapters contain information about configuring line cards
and 4-port ATA cards.
To install cards in the NBX 100 chassis:
1
Leave the top faceplate cover in place, and remove the other covers.
2
Install line cards and hub cards starting at the bottom slot.
You must install the NCP in the top-most slot. The order in which you
install other cards is not important.
3
Be sure the edges of the card ride in the chassis guide slots, and then
slide the card in until you feel slight resistance.
4
Press firmly on the front of the card until you feel it seat in the connector,
and then tighten the knurl knobs.
If you cannot seat the card with light pressure, remove it and check for
obstructions.
5
Cover any empty slots with blank faceplate covers, installing them with
the wide flange on the bottom.
CAUTION:
To ensure proper cooling and protection from
electromagnetic interference, install a cover over every blank slot.
