1.
To access the modules the associated front fan assembly must be opened first.
Important:
•
Before adding modules to a Sirius 800 router check that the power supplies fitted
can supply sufficient power to the router. See Appendix B for router power
requirements.
•
Rear panels must be fitted and fastened securely to the router frame before
inserting the front modules.
•
The rear panel fastening screws should not require any pressure when screwing
them into the router frame. They should screw in without any resistance until the
screw head secures the rear panel to the frame. If a rear panel fastening screw
binds up then it should be removed and the screw alignment should be checked
before the screw is refitted.
•
Do not overtighten the rear panel fastening screws.
Electrostatic Damage
Static precautions must be observed when inserting and removing all system modules

Note:
•
The fan assembly should be placed back into the closed position as soon as
possible after opening, as this ensures correct ventilation of the frame. Failure to
do this will result in failure.
•
In practice the maximum time that a fan assembly can be left open will depend on a
number of factors such as; ambient temperature, frame loading, crosspoint
routings, etc. To ensure correct operation under all conditions the fan assemblies
should be left open for no more than 4 minutes at a time.
