Drive Port Bypass
(one LED per port)

Note:

The drive

channel consists of
two FC ports. This
LED indicates the
drive port bypass
status of one of the
two FC ports that
made up a drive
channel. The LED
marked 6 shows
the status of the
other port.

problem

v

An SFP module
is inserted in the
port and the
connected fibre
channel is either
absent or not
properly
connected.

v

The storage
expansion
enclosure
connected to this
port is not
powered on.

v

There is a
problem with the
fibre channel
connection
between this port
and the fibre
channel port of
the connected
ESM in the
storage
expansion
enclosure.
