INSTALLATION CONSIDERATIONS
This fiber-optic link is supplied as a Standalone module. Units should be
installed in dry locations protected from extremes of temperature and
humidity.
C1-US, C1-EU, C1-AU OR C1-CH CARD CAGE RACKS
CAUTION: Although the units are hot-swappable and may be installed
without turning power off to the rack, ComNet recommends that the
power supply be turned off and that the rack power supply is disconnected
from any power source. Note: Remove electrical connector before
installing in card cage rack.
1. Make sure that the card is oriented right side up, and slide it into the
card guides in the rack until the edge connector at the back of the card
seats in the corresponding slot in the rack’s connector panel. Seating
may require thumb pressure on the top and bottom of the card’s front
panel.
CAUTION: Take care not to press on any of the LEDs.
2. Tighten the two thumb screws on the card until the front panel of the
card is seated against the front of the rack.
WARNING: Unit is to be used with a Listed Class 2 or LPS power supply.
IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is not
compromised.
