SSA-G8018-0652

The SSA-G8018-0652 has forty-eight 1000BASE-X SFP ports and four 10GBASE-X SFP+ ports, as
shown in Figure 2.

4 = 1000BASE-X SFP ports
Each of the 1000BASE-X SFP ports operates in full-duplex mode.
The SFP and SFP+ ports support a number of pluggable transceivers. For more information about the
transceivers, see http://www.extremenetworks.com/product/transceivers/.

AC Power Supplies

Two 460 watt AC power supply models, ordered separately, are available for the SSA switch:
•
SSA-FB-AC-PS-A—I/O port side air exhaust
•
SSA-FB-AC-PS-B—I/O port side air intake
Each power supply option contains a single non-reversible fan. The two power supply options are
differentiated by the direction of the power supply fan airflow. Power supply airflow must agree with
the airflow direction of the installed fan modules.
The SSA AC power supplies automatically adjust to the input voltage and frequency, which allows for an
input voltage of 100 to 240 VAC, and a frequency between 50 and 60 Hz. See the operating
specifications in SSA Switch Specifications
installations in North America, a 15 Amp power cord is required. See
page 25 for more details.
You can install up to two power supplies in the rear of the SSA chassis. All the power supply needs of
the SSA switch can be met by installing a single power supply. If you choose to use two power supplies,
system power redundancy is guaranteed if one supply is lost. Power supplies are hot swappable in
redundant power supply mode.
