Sirius 830 Installation Manual
2.4 Fiber Output Modules Warning
2.5 Cable Management
It is important that the cabling to and from the router is correctly labelled and routed. This will
simplify the work required if the installation needs to be changed or added to at a future date.
2.6 Power Supplies
The power supply shelves are separate 2RU modules. Power supply shelves are rack
mountable and can be placed above, below or remote from the Sirius frame.
The power supply alarm cable(s) and 48 V DC cables are supplied by SAM and can be
ordered as either 2.5 metre cables or 8 metre cables.

LASER SAFETY
The average optical output power does not exceed 0 dBm (1mW) under normal
operating conditions. Unused optical outputs should be covered to prevent direct
exposure to the laser beam.
Even though the power of these lasers is low, the beam should be treated with caution
and common sense because it is intense and concentrated. Laser radiation can cause
irreversible and permanent damage of eyesight. Please read the following guidelines
carefully:
•
Make sure that a fiber is connected to the board's fiber outputs before power is
applied. If a fiber cable (e.g. patchcord) is already connected to an output, make
sure that the cable's other end is connected, too, before powering up the board.
•
Do not look in the end of a fiber to see if light is coming out. The laser
wavelengths being used are totally invisible to the human eye and can cause
permanent damage. Always use optical instrumentation, such as an optical
power meter, to verify light output.
•
Cables connected to the router must be fitted with adequate vertical and horizontal
strain relief to avoid twisting of the rear panels causing damage to the router
connectors and loss of electrical/signal connection to the router.
•
Cables connected to the router should be routed so they do not cover any of the
frame fan exhausts as this can restrict airflow through the router.
•
Ensure that the power supply shelves are correctly earthed see section 2.7 for
details.
•
The power supply units are sealed and do not contain any serviceable items
•
Power supply shelves are heavy so it is advised that two people are needed to
support the weight of the power supply shelves during installation.
•
To prevent damage, power supply shelves should not be mounted using just the
front ears, and should have support at the rear of the shelves.
