1000BASE-X SFP ports
Each of the 1000BASE-X SFP ports operate in full-duplex mode.
The SFP and SFP+ ports support a number of pluggable transceivers. For more information about
the transceivers, see the following:

AC Power Supplies
Two 460 watt AC power supply models, which you must order 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 air flow. Power supply air flow must agree
with the air flow 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
For installations in North America, a 15 Amp power cord is required. See
Switch" on page 2-13 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.

power supply LED, see
Fans
The SSA switch comes with two installed fan modules to cool the system. The direction of the fan
module air flow is reversible. By default air flows from the I/O port side to the power supply side
of the unit. If your SSA switch configuration requires power supply side to I/O port side air flow,
