3.11. SFP Optics – Installation, removal, and precautions

The RX1512 can be ordered with SFP (Small Form-factor Pluggable) pluggable optics modules. SFP modules can be safely inserted and removed while the chassis is powered and operating. When inserting or removing optics, observe the following precautions:

•Ensure that dust caps are mounted on SFP cages at all times, unless you are in the process of inserting or removing an SFP module. The dust caps prevent the accumulation of residue or particles that might inhibit proper operation.

•Ensure that you have properly discharged any possible electrostatic build-up to prevent electrostatic discharges (ESD). This can be accomplished by proper grounding through an ESD wrist strap, or by touching earth or chassis ground before installing or removing optical modules. ESD can damage or shorten the life of optical modules when they are not plugged into a chassis.

•Ensure that SFP optical modules are always stored in an ESD-safe bag or other suitable ESD-safe environment. Keep SFP modules free from moisture and store them at the proper temperature (-40°C to +85°C).

•Disconnect all cables from the SFP module before inserting or removing the module.

•Use only components certified by RuggedCom Inc. with RuggedCom products. Damage can occur to optics and product if compatibility and reliability have not been properly assessed.
