How to Install a QSFP+ Transceiver
The switch supports 20 fixed 40G QSFP+ ports, plus up to 12 optional 40G QSFP+
expansion module ports. The supported QSFP+ transceiver types are listed below:
◆ 40GBASE-CR4 (Direct Attach Cable)
◆ 40GBASE-SR4
Note:
QSFP+ transceivers are hot-swappable. The switch does not need to be
powered off before installing or removing a transceiver.
Note:
QSFP+ transceivers are not provided in the switch package.
Follow these steps to install a QSFP+ transceiver:
1. Consider network and cabling requirements to select an appropriate
transceiver type that is also compatible with the switch transceiver support.
2. If the QSFP+ slot is covered with a rubber protective cap, remove the cap and
keep it for later replacement.
3. Insert the transceiver with the optical connector facing outward and the slot
connector facing down. Note that QSFP+ transceivers are keyed so they can
only be installed in the correct orientation.
4. Slide the transceiver into the slot until it clicks into place. If you do not
immediately connect a cable to the port, use a rubber protective cap to keep
the transceiver optics clean.
