Installation and Reference Guide
Mini-GBIC and SFP Modules
Intensity of Received Light
Intensity of received light refers to the optical input power received by the optical module. The unit is dBm. If the actual
received light intensity is less than the minimum value, the module may fail in connection or lose many frames. If the
actual received light intensity is greater than the maximum value, the module may be damaged.
Module Installation Precautions
Preparation before Installation
Before installation, electron static discharge (ESD) protection is needed. To avoid damages to the SFP modules and
electronic devices in the equipment caused by the static electricity generated during the installation, please wear the
anti-static wrist strap around the wrist and tighten the lock; make sure that the anti-static wrist strap has a good contact
with the skin and is well grounded.
Wearing jack type anti-static wrist strap, for example, is as shown in Figure 1-7:
Figure 1-7 Schematic Diagram for Wearing Jack Type Anti-static Wrist Strap
Installing the SFP Module
1. Reveal the handle of the SFP module to lock against the snap on top of the module, and pinch the both sides of the
SFP module to push it levelly and slowly into the optical module slot until the optical module firmly connects to the slot
(there would be a click sound if the optical module is correctly connected to the slot), as shown in Figure 1-8:
Figure 1-8 Installing the SFP Optical Module
2. When you connect the SFP module to the optical fiber network, use the optical fiber jumper. Based on the connector
type of the interconnecting ports, choose the jumper with corresponding connectors.
3.
After installing the module of the optical fiber jumper, the switch port indicator “LINK/ACT” will be on; otherwise, check
that the optical fiber jumper is correctly connected.
