2.8 Pluggable optics – Installation, removal, and
precautions
The RSG2300 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.
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, Figure 26 shows the
proper orientation of SFP 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.
