3.2.8. Pluggable optics – Installation, removal, and precautions
The RS2000 series of products can be ordered with two pluggable optical form factors: SFP (Small
Form-factor Pluggable), and GBIC (GigaBit Interface Converter). SFP and GBIC modules can
be safely inserted and removed while the chassis is powered and operating – a feature also
referred to as “hot-swappable”. Nevertheless, 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 might inhibit proper operation.
• Ensuring that the user has properly discharged any possible electrostatic build-up in order to
prevent electrostatic discharges (ESD). This can be accomplished by properly 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.
• Ensuring that SFP and GBIC optical modules are always stored in an ESD-safe bag or other
suitable ESD-safe environment, free from moisture and stored at the proper temperature (–40
to +85°C).
• Disconnecting all cables from the SFP or GBIC module prior to insertion or removal of the
module.
• Using only optics certified by RuggedCom Inc. with RuggedCom products. Damage can occur
to optics and product if compatibility and reliability have not been properly assessed.
3.2.8.1. Module Insertion – GBIC and SFP
Special attention must be paid to the orientation of SFP and GBIC modules upon installation in the
RuggedSwitch® chassis. For example, the figures below show the proper orientation of SFP and
GBIC modules installed to both upper and lower slots. Modules on the upper row must be inserted
top-side up, and modules on the lower row must be inserted top-side down. SFP modules should
be inserted with the bail-latch in the locked position.

Both SFP and GBIC modules should gently slide into their ports and should lock in place when
fully inserted. Dust covers should be in place when installing the modules, and should always be
in place when cables are not connected.
3.2.8.2. GBIC Module Removal
GBIC modules have two locking latches, one on either side of the module, as shown in the figure
below. To remove a GBIC module, disconnect any cables and replace the dust cover to protect
