Note:
Base stations with cables longer than 1.9 km must always be connected to a CLU with code
REX-BRD0014 (ROFNB 157 11/2). Base stations with cables of up to 1.9 km can be connected to a
SLU with code REX-BRD0015 (ROFNB 157 16/1) or a CLU-S with code REX-BRD0016 (ROFNB 157
16/2). Only applicable for KRCNB 201 and KRCNB 301, 302 and 303 base station of revision R1n or
R2n.
Do not power the base station via the EPP terminals from a local power source and the radio exchange
simultaneously. As the two EPP inputs of the base station are interconnected in the base station, the
two power sources would be interconnected. However, the base station can be powered via the data
pairs from the radio exchange and the local power source simultaneously because they are
interconnected via rectifiers.
If a base station is powered locally (using an AC-adapter) EPP pairs must not be connected.
1. Connect the base station cable to the MDF.
2. Write down the relationship between the signal names (see table 5) and the colour codes of the
cable pairs used in the base station cable. You will need this information to connect the base
station connector.
3. Make a copy of the base station identification and location sheet given at the end of this chapter
(table
6) and fill it in according to the connections that are made. Refer to section ‘System
description, Numbering conventions’ in this manual for base station numbers. An example on
how to fill in the sheet is given in table
4.
Base station power
Following installation steps are necessary when the base stations are powered via the modular cabinet.
Refer to chapter 151 on how to supply base station power to the MCCB.
1. Check that connectors PW1 on the MCCB are connected to the base station power connectors
on the leftmost CLU, CLU-S or SLU using the CLU/MCCB power cable (see figure
87).
2. Connect PW2 – PW7 to the power connections of the other CLU, CLU-S or SLUs starting at the
next CLU, CLU-S or SLU.
