4. Installing QSFP28 Transceiver Module
4-1 Installing the QSFP28 Ethernet Transceiver Module
Please follow these steps to install the QSFP28 Ethernet transceiver module:
1. Power on the Switch and place the Switch on a flat surface. Install the new QSFP28
Ethernet transceiver module by inserting it into the slot and sliding it in until it stops (See
Figure 1). Press it firmly until you hear the module snap into place. Never force, twist or
bend the QSFP28 Ethernet transceiver module. The QSFP28 Ethernet transceiver mod-
ule slides in smoothly and the Switch will automatically detect the new module.
