CAUTION
SC4812ET Span Line Labeling for Span B and Span C is
swapped
-On the SC4812ET’s, the span cable internal to the base station
that connects the 50 pin header on the I/O plate to the CSU has
Span B and Span C (RJ-45) connectors mis-labeled.
-CFE will punch down the span on the 50 pair bunchblock as per
Motorola documentation and punchdown chart. When conecting
the span input to the CSU re-label “Span B” cable to”Span C”
cable to “Span B”. Connect to CSU as per documentation
Note: The labeling issue on the cable from the I/O plate to the
CSU Part Number 3086601H01 Rev C shall be corrected on
revision “D” to address this issue. The cut over date to Rev. D
will be approximately January 30, 2001.
