Port Led Patterns During Normal Operation; Ethernet Led Patterns - IBM SAN16B-2 - TotalStorage Express Model Switch User And Service Manual

Port LED patterns
Each port has two LEDs: a port speed and a port status indicator. These LEDs are
located below both rows of ports, and each set is labeled with the port number.
Table 7 shows the LED location, color, and meaning for these port LEDs.

Ethernet LED patterns

Each Ethernet port has two LEDs, the Link LED, and the Speed LED (see Figure 9
on page 22 for the Ethernet port and Ethernet LED locations). Table 8 on page 25
describes the location, color, and meaning for the Ethernet LED activity.

Status of hardware
No light or signal carrier (SFP or
cable) detected.
Port is online (connected to external
device) but has no traffic.
Port is online but segmented,
indicating a loopback cable or
incompatible switch.
Port is in internal loopback
(diagnostic).
Port is online with traffic flowing
through port.
Port is receiving light or signal carrier
but is not yet online.
Port is disabled as the result of
diagnostics or portDisable command.
If all ports are slow-flashing amber,
the switch could be disabled.
Port is faulty.
Port is bypassed.
Port is transmitting/receiving at 2
Gb/sec.
Port is transmitting/receiving at 1
Gb/sec.
Port is transmitting/receiving at 4
Gb/sec.
Recommended action
Check SFP and cable.
No action required.
Verify that the correct device is
connected to port and that the switch
and port settings are correct.
No action required.
No action required.
No action required.
Enable the port using the portEnable
command. See the Brocade Fabric
OS Command Reference Manual for
more information.
If all ports are slow-flashing amber,
enable the switch using the
switchEnable command.
Perform the following steps:
1. Check the Port Status LEDs, error
log, SFP, and cable or loopback
plug.
2. Clear the error log.
3. Rerun the diagnostics to verify
that the error condition is fixed.
Check configuration of Fibre Channel
loop.
