POWER APPLICATION AND SYSTEM CHECKOUT
Ensure
that a 0.5 Amp fuse is in place in the fuse panel for each DSX-4U chassis in the bay.
Fuses
from left to right (as viewed from the front) correlate to chassis from bottom to top, with
one
fuse for each chassis. Apply –48 Vdc office battery at the office distribution panel.
Cross-connect
wiring can be checked as necessary by pulling the tracer lamp switch button on
any
DSX-4U circuit module. Pulling of this button should cause the corresponding tracer lamp
and
the tracer lamp at the other end of the cross connect to flash for approximately 30 seconds
and
then remain lit until the button is pushed back in.
