Installing the NBX 100 Chassis
69
A well-organized physical configuration can simplify:
■
Management of incoming telephone lines, by associating line card
ports with specific telephone numbers
■
Troubleshooting, by associating groups of channel numbers with
specific cards
■
System expansion
Installing the
NBX 100 Chassis
You can mount the NBX 100 chassis on the wall or in an equipment rack.
Installing the Disk
Drive
The disk drive holds the NBX 100 Call Processor software, the
configuration database, and NBX Messaging software.
3Com recommends that you install the disk drive in the chassis before
you mount the chassis on a wall or in a rack.
A system requires only one Call Processor and disk drive, even when you
have more than one chassis. For example, an installation can have two
chassis to accommodate additional line cards, but only one chassis holds
the Call Processor and disk drive.
CAUTION:
To avoid damage to electronic circuits, always wear an
anti-static grounding strap when handling the disk drive or NBX system
cards. When you ground the strap, do not ground it to the NBX chassis
because the chassis is not grounded until you install it in a properly
grounded setting.
If you purchased an upgrade to the NBX voice mail (to add more voice
mail ports), you cannot install the upgrade license key unless the disk
drive is installed in the correct chassis. One of the chassis boxes has an
extra label which lists a voice mail key code. Be sure to install the disk
drive in the chassis that came with the key code label. If you discarded
the chassis boxes, look on the system invoice for the chassis containing
the voice mail key code label.
