Install Optional Components

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

Pluggable Transceiver Modules

Extreme Networks offers several optical transceiver modules for transmitting and
receiving data over optical fiber rather than through electrical wires.

Optical Cables

Direct-attach copper and fiber cables provide connections between populated SFP+,
SFP28, QSFP+, and QSFP28 ports.

Breakout cables

The copper breakout cables are terminated with optical connectors and are available
in 1m, 3m, 5m, or greater lengths. No additional connectors or cabling are required
when using the copper breakout. When using the fiber breakout cables, additional
10Gb optics are required.
For 7720 Series switches running either Fabric Engine or Switch Engine, interfaces
0/1 through 0/27 and 0/29 through 0/32 support up to 4 10GbE, 4 25GbE, 1 40GbE, or
1 100GbE ports each in breakout mode when using the appropriate optics. Interface
0/28 cannot be partitioned, but it supports 1 40GbE or 1 100GbE port. See the
Optics website to determine the appropriate optics.

Install Internal Power Supplies

If your device does not come with an installed internal power supply, you can install
one or two power supplies. All installed power supplies must have the same airflow
direction (front-to-back or back-to-front) and must also match the airflow direction of
the fan modules.
This switch supports 800 W AC or DC power supply units.
•
If the power supply module has a red tab, the airflow is front-to-back.
•
If the power supply module has a blue tab, the airflow is back-to-front.
The following internal power supplies (PSUs) are available for the switch:
800 W AC or DC PSU
Part numbers XN-ACPWR-800W-F and XN-DCPWR-550W-FB provide front-to-back
airflow for cooling, and AC and DC power, respectively.
