3.2 BTS3902E PGND Cables
The BTS3902E PGND cable connects a BTS3902E and a ground bar, ensuring proper grounding
of the BTS3902E. The maximum length of a PGND cable is 30 m (98.42 ft).
Exterior
The PGND cable is green and yellow. Both ends of the cable are OT terminals. Figure 3-1 shows
the PGND cable.
Figure 3-1 PGND cable
(1) OT terminal
NOTE
l When an AC surge protection box (which is optional) is configured for a BTS3902E that uses AC
power supply, two PGND cables are required. One provides equipotential connection between the AC
surge protection box and the BTS3902E, and the other connects the AC surge protection box and a
ground bar to ensure proper grounding of the AC surge protection box.
l One end of the PGND cable connected to the BTS3902E or AC surge protection box is an M6 OT
terminal. The other end connected to the ground bar is an OT terminal added onsite.
Cables
Specifications of the used PGND cables vary with the operating frequency band. You are advised
to prepare the PGND cables with a cross-sectional area not less than that of the copper-core
cable of the same specifications. Table 3-4 lists the specifications of PGND cables.

5 Replacing an Optical Module
Replacing an Optical Module
An optical module implements optical-electrical conversion, enabling optical transmission
between a BTS3902E and other devices. You must disconnect the fiber optic cable from an
optical module before replacing the optical module. Disconnecting the fiber optic cable
interrupts the transmission of optical signals.
Prerequisites
The type and number of optical modules to be replaced are confirmed, and new optical
modules are ready.
Tools and materials, such as electrostatic discharge (ESD) gloves, M4 Phillips
screwdrivers, and an ESD box or bag, are ready.
The optical module is installed on the OPT0 or OPT1 port on the BTS3902E.
Optical modules are hot-swappable.
It takes about five minutes to replace an optical module on the BTS3902E, which involves
disconnecting the fiber optic cable, removing the faulty optical module, inserting a new
optical module, reconnecting the fiber optic cable, and waiting for the link on the Ethernet
optical port to resume.
Context
Procedure
Step 1 Wear ESD gloves.
NOTICE
Take proper ESD protection measures; for example, wear ESD gloves, to prevent electrostatic
damage to the boards, modules, or electronic components.
Step 2 Record the connections of the optical module and fiber optic cable.
Step 3 Press the latch on the connector of the fiber optic cable, and then remove the connector from the
faulty optical module.

5 Replacing an Optical Module
CAUTION
Do not look into the fiber optic cable or optical module without eye protection after the fiber
optic cable is removed from the optical module.
Step 4 Lower the puller on the faulty optical module, and then pull the puller until the optical module
is removed from the BTS3902E.
Step 5 Prepare an optical module of the same type as the faulty optical module according to the label
on the module. Install the new optical module onto the BTS3902E.
NOTE
