Powering Up the DSU

CAUTION
The power cord and ac
transformer have a 3-wire
grounding-type plug with a
grounding pin. This is a safety
feature. Grounding of the unit
is vital to ensure safe
operation. Do not defeat the
purpose of the grounding
plug by modifying it or by
using an adapter.
Prior to installation, use an
outlet tester or voltmeter to
check the ac receptacle for
earth ground. If the power
source does not provide a
ground connection, consult
an electrician to determine
another method of grounding
the unit before proceeding
with the installation.
NOTE
Before connecting the DSU to
any network, ensure that
approved primary protectors
have been installed on the
circuit in accordance with Article
800 of the National Electric
Code, NFPA 70, in the United
States and Section 60 of the
Canadian Electric Code, Part 1,
in Canada.

Power-Up Routine

When you apply power for the first time, the DSU
performs a power-up routine and:
Determines what hardware options are installed, if
any. These may include DBM and MUX for
TDM/MCMP.
Runs a Device Test on the DSU and each installed
hardware option. All front panel lights flash on and
off.
