5. Installation and Test
5.1. Inspect after Opening
Please first check if the models and part numbers are in consistence, and also check if the
equipments are damaged.
5.2. Preparation before Installation
z Carefully read this manual
z Prepare all kinds of the cable. Ensure that they are not short-circuited. Refer to
Appendix A for cable making.
z Ensure RC004-16 is properly installed, and the chassis is well connected with the
ground.
z Prepare the BERT and optical power meter for test of line quality.
z Change the dip-switch setting on the bottom panel if 120 Ohm balanced signal interface
is required.
z Set up the fault-pass-through enabled if using the function.
z This module does not support hot-swapping
5.3. Installation Procedure
5.3.1. Installing the Module into the Chassis
Insert the module into any service slot from 1
st
to 15
th
, with PWR indicator upside. The MPU
slot is particular for the network management module, thus cannot be inserted with service
modules.
Installing fiber-optic multiplexer in MPU slot will cause damage to the module itself or the
back panel of the chassis.
5.3.2. Connecting Cables
z E1 port
The upside of RC004-16 chassis, corresponding to fiber-optic module, has 2 groups of
DB37 male interfaces. The upper one is for the 1
st
– 4
th
E1 channels of Unit 1, and the lower
one for the 1
st
– 4
th
E1 channels of Unit 2.
It is suggested that users use SYV75-2-2 coaxial cables to connect the BNC connector.
Users can connect a CC4B-8G adapter on DB37 male interface to connect CC3-K3 coaxial
cables.
If using 120 Ohm balanced interface, users can connect the DB37 male interface with
DB37 female-connector twisted-pair.
z Optical interface
Plug the SC fiber tail into optical interface (push hard until to the deep end). If not sure
about transmission direction, it’s advised first to turn on the power of device and then plug
