Table 18 Fibre Channel switch system indicators
System indicator Description
Power A green indicator. When lit, this indicates that the switch is plugged in and the
internal power is functional.
Loop operational A green indicator. When lit, this indicates that the Fibre Channel loop has
completed initialization and is now operational.
POST fault An amber indicator. When lit, this indicates that the internal hardware self-test
failed and the switch will not function.
OvertTemp An amber indicator. When lit, this indicates that the ambient temperature has
exceeded 40° C. The switch is still functional; however you should correct the
problem immediately. The Over temp indicator turns off when the problem is
corrected.
Table 19 describes the port indicators.
Table 19 Fibre Channel switch port indicators
SFP status
indicator
(Green)
Port bypass
indicator (Amber)
Description
Off Off Indicates that the port does not have an SFP installed and is
bypassed by the loop.
On Off Indicates that the port is operating normally. The port and device
are fully operational.
On On Indicates the that port is in a bypassed state. The port is
non-operational due to loss of signal, poor signal integrity, or
the Loop Initialization Procedure (LIP).Note: This condition is
also normal when the SFP is present but not attached to a Fibre
Channel drive enclosure node or when the SFP is present and
attached to only a cable assembly. Attaching the SFP to a device
and plugging it into the port should initiate the LIP by the attached
device.
Off On Indicates a Tx fault. The port is non-operational due to an SFP
transmitter fault, improperly-seated SFP, or another failed device.
Problem isolation
Table 20 lists several basic problems and their solutions.
