Inserting the T1 Digital Line Card
To insert the T1 card:
1 Find the MAC address of the T1 card on the label on the card.
2 Record the MAC address for the configuration process.
3 Select a slot for the T1 card in the chassis and use a Phillips screwdriver to
remove the blank faceplate from the slot.
4 Insert the T1 card into the slot.
5 Slide the T1 card into the chassis until you feel it touch the connectors.
6 To seat the T1 card into the connectors, apply firm pressure to both the
left and right sides of the front of the card.
7 Tighten the left and right screws on the front of the T1 card to secure it
to the chassis.
CAUTION: Wait 3 minutes for the T1 card to initialize and for the system
to update its database. The T1 card reboots twice during the initialization
process. If you attach a console cable to the COM1 port on the T1 card
and use Hyperterm software to view the text output from the card, you
see status messages associated with the two reboot processes. See
"Connecting a Computer to a Serial Port"
Another way that you can be sure that it is safe to proceed is to examine
the status lights on the front panel of the T1 card. After the Auto
Discovery process has completed, and before you connect the T1 Digital
Line Card to the telephone company's T1 line, the CF (Carrier Fail) light
should appear solid green on a 3C10116C card. On a 3C10116D card,
the POST, DNLD, CARD and NCP lights should appear solid green. For
more information on T1 card status lights, see
page 208.
You are now ready to configure the T1 Digital Line Card for either
DS1 signaling or ISDN PRI signaling. Before you configure a T1 card, be
sure you have configured the system Dial Plan for you needs as described
in Chapter 2.
These sections tell you how to use the NBX NetSet utility to set up your T1
Digital Line Card for DS1 protocol:
