Install Optional Components; Pluggable Transceiver Modules; Optical Cables; Breakout Cables - Extreme Networks 8520 Series Hardware Installation Manual

Install Optional Components

If the switch does not have an installed power supply, install one or two power supplies using the
instructions in
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
website.

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 the 8520-48Y switch, interfaces 0/49 and 0/56 support up to 8 10GbE or up to 8 25GbE ports in
breakout mode when using the appropriate optics. See the
appropriate optics.
For the 8520-48XT switch, interfaces 0/49 and 0/54 support up to 8 10GbE or up to 8 25GbE ports in
breakout mode when using the appropriate optics. See the
appropriate optics.
The first and last ports of the 8520 Series uplinks are capable of breakouts (they are color coded
differently too).
•
For 8520-48Y models, the 1st and last uplink ports are ports 49 and 56
•
For 8520-48XT models, the 1st and last uplink ports are ports 49 and 54

Install Internal Power Supplies

If your device does not come with an installed internal power supply, you can install one or two power
supplies.
The 8520 Series switch supports 750 W power supply units using either AC or DC power.
