Administering a Changed System

RENUMBERING
AFTER REPLACING
OR ADDING
MODULES
Performing system administration on an existing system
that has been changed involves some special
considerations. Read the following information carefully
before you install or remove modules or change the basic
settings for a MERLIN
You may delete important system administration settings
if you:
Install or remove modules in the control unit
•
• Change the system size (small or large) or type
(square, pooled, or behind-switch)
• Change a standard voice terminal setting to an
attendant position setting or vice versa
If you replace a module with one of a different type, you
must readminister the system to reassign numbers to lines
and stations. The procedure for renumbering the system
appears below.
Replacing station modules may require
NOTE:
readministration of features that are related to
particular types of stations. For example, you
might replace an analog station module that
contained jacks used for attendant positions with
a digital station module. Since digital voice
terminals can't be attendant positions, you would
need to reassign those attendant positions to
analog station jacks on a different module.
If you add modules without changing the modules that are
already in place, the system assigns numbers to the
additional lines and/or stations automatically. In that case,
the numbers for the lines and stations that you've already
administered don't change, so you don't need to perform
the renumbering procedure. (If you expand the system, be
sure not to leave any empty slots between modules.)
