2. When you connect the 100G QSFP28 module to the optical fiber network, use the optical fiber patch cord. Based on the
interface type of the Internet ports, choose the jumper with corresponding interfaces.
3.. After installing the module of the optical fiber patch cord, the switch po
rt indicator “LINK/ACT” will be on; otherwise,
check that the optical fiber patch cord is correctly connected.
Precautions during installing:
The optical module cannot be inserted backwards. The correct method of inserting QSFP28 optical module is shown
in Figure 6-7 and Figure 6-8; the method of inserting QSFP28 cable is shown in Figure 6-11 and 6-12. If the optical
module cannot be inserted to the end from one direction, do not force to push it in and please try another direction.
It is recommended that before installing the fiber-optic lines, the protecting rubber plug on the optical port of optical
modules shall not be pulled out.
It is recommended that users shall not insert the fiber QSFP28 module into which optical fiber has already been
inserted directly into the slot. Please proceed with installation after the optical fiber is pulled out.
In the process of installing QSFP28 module, please do not directly touch the connecting finger part of the QSFP28
modules by hand.
Please do not crush, bend, fold fiber or overbend the fiber, otherwise it may lead to reduced system performance or
loss of transmitted data.
Removing the 100G QSFP28 Optical Module
1. Pull out the optical fiber line.
2. For the snap-in module, pull the QSFP28 module handle downward to the horizontal position, gently pull the snap, and
then pull out the QSFP28 module smoothly. As shown in the Figure 6-9. For the pull-tab module, directly pull the tab to
remove the QSFP28 module steadily. As shown in the Figure 6-10.
