The SAN Router, rear view

All ports and connectors are located on the front of the SAN Router,
except for the power connectors, as described in the following
paragraphs. The rear of the SAN Router contains only the power
connectors and cooling fans. The Field Replaceable Units (FRUs) are
the optical transceivers, power supplies (which include internal fans),
and base machine.
There are two standard power connections located on the rear of the
SAN Router. Each of these power connections supplies AC power to
a different power supply for power redundancy and backup. Either
power supply can support the SAN Router operation, but it is
recommended that both be connected, each to a different power
source.
NOTE: If one power supply fails, the SAN Router will continue to operate
but the failed power supply should be replaced as soon as possible to retain
redundancy.
There are twelve user-configurable fibre channel ports located on the
front of the SAN Router, labeled 1 through 12. These port connections
hold SFP transceivers that support FC connectivity at 1 or 2 Gbps or
GE connectivity at 1 Gbps. The ports can be configured as:
• FC_Auto (default)
• FL_Port
• F_Port
• L_Port
• R_Port
