•
Before installing the device, read the planning instructions in the
TCX1000
Programmable ROADM Hardware Guide
to make sure that the site meets power,
environmental, and clearance requirements for the TCX1000-RDM20.
•
For the cooling system to function properly, the airflow around the chassis must be
unrestricted.
•
Before connecting the device to a power source, read the installation instructions in
the TCX1000-RDM20 documentation.
•
If the rack or cabinet has stabilizing devices, install them in the rack before mounting
or servicing the TCX1000-RDM20 in the rack or cabinet.
•
Before installing or after removing an electrical component, always place it
component-side up on a flat antistatic mat or in an electrostatic bag.
•
Do not work on the TCX1000-RDM20 or connect or disconnect cables during electrical
storms.
•
Before working on equipment that is connected to power lines, remove jewelry, including
rings, necklaces, and watches. Metal objects heat up when connected to power and
ground and can cause serious burns or become welded to the terminals.
•
Wire the DC power distribution unit by using the appropriate lugs. When connecting
power, the proper wiring sequence is ground to ground, +RTN to +RTN, and then –48 V
to –48 V. When disconnecting power, the proper wiring sequence is –48 V to –48 V,
+RTN to +RTN, and then ground to ground. Always connect the ground wire first and
disconnect it last.
