SFP Module Replacement
This chapter describes how to replace small-form-factor pluggable (SFP) modules. SFP modules are 
inserted into the SFP module slot on the Cisco 3270 Rugged Router card. These modules provide the 
uplink optical interfaces, laser send (TX) and laser receive (RX).
The following are qualified Gigabit SFP modules:
  •
Gigabit Multi-Mode SFP (Cisco part number: GLC-SX-MM-RGD):
  •
Gigabit Single-Mode SFP (Cisco part number: GLC-LX-SM-RGD):
Each SFP must be of the same type as the SFP on the other end of the cable, and the cable must not 
exceed the stipulated cable length for reliable communications. 
 shows an SFP module that 
has a bale-clasp latch. 
Caution
We strongly recommend that you not install or remove the SFP module while the fiber-optic cable is 
attached to it because of the potential damage to the cables, to the cable connector, or to the optical 
interfaces in the SFP module. Disconnect the cable before you remove or install an SFP module.
 
 
Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP 
modules more often than is necessary.

Caution
To avoid damaging the cables, follow standard fiber optic cleaning procedures when connecting fiber 
optic cables to fiber-optic ports.
