Installing the SLPU
NOTE
The SLPU is generally equipped with two UELP boards and one UFLP board. If more than eight E1
signals are transmitted, one or two extra UELP boards need to be delivered with the equipment and need
to be installed in the vacant slots of the equipment on site. If more than 12 E1 signals are transmitted, the
UFLP board needs to be replaced with the UELP board. The removed UFLP board needs to be returned
to the local representative office of Huawei.
