INSTALLATION CONSIDERATIONS 

This fiber-optic link is supplied as a Standalone/Rack 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 rated 

9-12 VDC @ 1A.

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.
