Section 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.
