(Figure 3-4: Inserting a QSFP28/QSFP-DD Transceiver into a Slot)
To install a QSFP28/QSFP-DD transceiver, follow these steps:
1. Consider network and cabling requirements to select an appropriate QSFP28/QSFP-DD
transceiver type.
2. Insert the transceiver with the optical connector facing outward and the slot connector
facing down. Note that QSFP28/QSFP-DD transceivers are keyed so they can only be
installed in one orientation.
3. Slide the QSFP28/QSFP-DD transceiver into the slot until it clicks into place.
NOTE:
•
QSFP28/QSFP-DD transceivers are hot-swappable. The switch does not
need to be powered off before installing or removing a transceiver. However,
always first disconnect the network cable before removing a transceiver.
•
QSFP28/QSFP-DD transceivers are not provided in the switch package.
