NOTE:
This procedure may direct you to replace the
DSXBIU
in the NBS or a DT
Server at a
SLC
-2000 HDT. If you replace the
DSXBIU
, the system may start to
download software into the new
DSXBIU
. You can verify this by observing that
the
CONFIG
LED flashes on the
DSXBIU
. Wait for the flashing to end. The
download takes about 4 hours. Wait for the download to complete before
proceeding to the next step.
1. Is trouble on a single NBS or DT Server, or associated with a shelf 1 or shelf
2), or single digroup?
2. If you are at the RT, continue with
Step
3
; if you are at the DT or NBS, proceed
to
Step 7
; if you are at the central office, go to the RT unless MLT test results
indicate otherwise.
3. Press the
LED TEST
button and verify that all DT Server indicators light.
Quickly replace the DT Server circuit pack if they do not.
Comment:
For
SLC
-2000 HDTs
, the
INCOMP
LED on the MDC circuit pack
will light and the DT Server's LEDs will not light if the shelf is
configured for
METL
. If a replacement DT Server's LEDs do not
light, verify that the shelf is configured for
FITL
using the user
interface panel (UIP) SET-DISTN command. If necessary,
remove both
MDC
packs in the shelf (upper or lower section) and
change the distribution mode to
FITL
. Then reseat the
MDC
packs and repeat the LED test.
If
NBS
or
DT
Server, continue with
Step
2.
If
otherwise
, use 363-208-001,
SLC
-2000
User Service

to clear multiple channel trouble.
