2.5.3 Pluggable optics – Installation, removal, and precautions
The RS940G can be ordered with pluggable optic form factors such as SFP (Small Form-factor
Pluggable). These modules can be safely inserted and removed while the chassis is powered and
operating – this feature is also known as "hot-swappable". When inserting or removing optics there
are several precautions that should be taken. They include:
 Ensuring that dust caps are mounted on SFP cages at all times unless a user is in the process
of inserting or removing an SFP module. The dust caps will prevent the accumulation of
residue or particles that may inhibit proper operation.
 Ensuring that the user has properly discharged any possible electrostatic build-up and
electrostatic discharges (ESD). This can be accomplished by properly user 'grounding' via an
ESD wrist strap, or by touching earth or chassis ground before performing installation or
removal of optics. ESD can damage or shorten the life of optical modules when not plugged
into a chassis.
 SFP and GBIC optical modules should always be stored in an ESD safe bag or other suitable
ESD safe environment, free from moisture and stored at proper storage temperature (–40 to
+85C).
 Disconnect all cables from SFP or GBIC module before insertion or removal of module.
 Only RuggedCom Inc. certified optics should be used on RuggedCom products. Damage can
occur to optics and product if compatibility and reliability have not been properly assessed.
2.5.4 Module Insertion – SFPs
To insert SFPs, special attention should be taken into the proper module orientation. SFPs should
be inserted with dust cover in place, and the bail-latch in the locked position. Module should gently
slide into port and should lock in place when module is fully inserted. To protect optics, dust
covers should always be installed when cables are not connected.
2.5.5 SFP Module Removal
SFP Modules are removed using the metal bail latch located on the top of the module shown in
Figure 12. To remove the SFP module, disconnect any cable and replace with dust cover to
protect the optics. User should grasp bail latch and gently pull outwards to unlock and remove the
SFP module. Removal of the SFP module is shown further in Figure 13. The module should be
immediately stored in an ESD-safe environment.
