Replacing the SFP Module
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.
Figure 4-1 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 inserting 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.
