c. Use four small mounting screws (provided) to attach the bracket to the switch.
2. Attach the other short mounting bracket to the other side of the switch housing, as
you did in step 2.
3. Secure the brackets to the rack posts using rack-mounting screws that are
appropriate for the rack (not provided).
If the switch comes with installed power supplies, skip to the topic: Turn on the Switch
on page 66.
If the switch does not have an installed power supply, install one or two power supplies
using the instructions in Install Internal Power Supplies on page 60.
Install Optional Components
After the switch is secured to the rack, install optional components.
ExtremeSwitching switches support the use of pluggable transceivers and cables in the
SFP+, SFP28, QSFP+, and QSFP28 formats.
For a list of the optical components supported with ExtremeSwitching devices, see the
Extreme Optics website.
Pluggable Transceiver Modules
Extreme Networks offers several optical transceiver modules for transmitting and
receiving data over optical ber rather than through electrical wires.
