25G SFP28 Modules
Module Installation Precautions
Preparation before Installation
Before installation, electron static discharge (ESD) protection is needed. To avoid damages to the electronic devices in
the 25G SFP28 optical modules and 25G SFP28 cables 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 4-6:

Installing the 25G SFP28 Optical Module
1. Reveal the handle of the 25G SFP28 transceiver module to lock against the snap on top of the module, and pinch the
both sides of the 25G SFP28 optical 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 4-7:

2. When you connect the 25G SFP28 optical 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.
4. Precautions during installing:
The optical module cannot be inserted inversely. If the optical module cannot be inserted to the end along one
direction, do not forcibly push it in and please try another direction.
