LOCATION
As with any electrical device, the OSD2155 together with the OSD370/OSD350 chassis should be
placed where the unit will not be subjected to extreme temperatures, humidity, or electromagnetic
interference. Specifically, the site selected should meet the following requirements:
•
The ambient temperature should be between -20°C to 75°C (-4°F
to 167°F).
•
The relative humidity should be less than 95 percent, non-condensing.
•
Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards.
•
Make sure that the switch receives adequate ventilation. Do not block or obstruct the
ventilation holes on the chassis.

FITTING SFP CONNECTORS
Care should be taken when inserting/removing the SFP connectors from the SFP port as SFP modules
are Electrostatic (ES) sensitive and Electrostatic Discharge (ESD) precautions should be taken when
installing. Ensure that the SFP is fully engaged and latched into position.
Inserting SFP
– Ensure that the SFP lever is in the locked position and insert into appropriate SFP
port. Gently push the SFP until it locks into place. Remove plastic/rubber dust cap and fit appropriate
fiber cable.
Removing SFP
– Remove fiber connector. Pull the SFP lever down to unlock SFP from housing.
Using the lever, gently pull the SFP out.
