Chapter 7 Device Installation Preparation and Connection

7.1 Checking and preparation before installation

7.1.1 Make sure that the E1 cable applied meet the requirement of the device

For RC832-30, coaxial cable of SYV75-5, SYV75-3 and SYV75-2-2 can be used as E1 cable.
The E1 interfaces of RC832-30 are 75Ω unbalanced E1 interfaces. Please check the type, pin
definition and impedance of the E1 interface of the device on the opposite site of the communication
before connection. Please check the user manuals for devices that communicate with RC832-30 via
E1 for information.
For RC832-30-BL, 22AWG or 24AWG twisted pair can be used as E1 cable.
The E1 interfaces of RC832-30-BL are 120Ω unbalanced E1 interfaces. Please check the type, pin
definition and impedance of the E1 interface of the device on the opposite site of the communication
before connection. Please check the user manuals for devices that communicate with RC832-30 via
E1 for information.

7.1.2 Make sure that the fiber applied matches the requirement of the device

For RC832-30(-BL)-M, please use multi-mode fiber with DSC connector.
For RC832-30(-BL)-S1/S2/S3, please use single-mode fiber with DSC connector.
For RC832-30(-BL)-SS15/ SS25, please use single-mode fiber with SC/PC connector.

7.1.3 Confirm the fiber cable type applied

The cable type for the interface of multi-mode fiber:
62.5/125um multi-mode fiber or 50/125um multi-mode fiber
The cable type for the interface of single-mode fiber:
9/125um single-mode fiber
Please check the model and the number of the device and spare parts according to the
packing list. Please be sure that the appearance of the device is intact. If there is any evidence
that the device has been affected by damp, please dry it before installation.
Please read this manual with caution before installing the device.
Please have all types of cables that are needed ready and make sure there are no short circuits
and open circuits.
Please make sure that the power supply of the chassis is in the operating voltage range; please
have the rack of the chassis device well earthed.
Please prepare BER tester, optical power meter for line quality testing.
Please fix the chassis on to a 19-inch rack or place it on a balanced, stable and safe place,
please be sure the environment meets the requirements of the device.
