Table 24 Fibre Channel switch port LEDs
SFP status LED
Green
Port bypassed
LED amber
Description
Off Off
Indicates that the port does not have an SFP in stalled and is
bypassed by the loop.
On
Off
Indicates that the port is operating normally. The por t and device
are fully oper
ational.
On On
Indicates the that port is in a bypassed state. The port is
non-operational due to loss of signal, p oor signal integrity, or the
Loop Initialization Procedure (LIP) .NOTE: This condition is also
normal when the SFP is present but not attached to an FC-AL 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 L IP 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 a nother failed device.
Problem i
solation
Table 25 lists several basic problems and their solutions.
Table 25 Fibre Channel switch basic troubleshooting
Problem Recommended action
SFPs a re installed in ports but no LEDs
are lit.
1. Ve ri f y
that the power cord is firmly seated in the switch and is
connecte
d to the power outlet.2. Check the power LE D to verify
that the
switch is on.
SFP is installed, but the Port Bypassed
LED is lit.
Re-seat the SFP. If the same condition occurs, the SFP is probably
faulty and should be replaced.
SFP is installed, but the SFP Status LED
and the Port Bypassed LED are lit.
This condition indicates that the switch is not receiving a valid
Fibre Channel signal or that the switch is receiving an LIP.1. Ensure
that the switch is p owered on.2. Contact your authorized service
representative for further assistance.
SFP is i
nstalled and the SFP Status
LED is
lit, but the devices are not
commu
nicating.
This co
ndition indicates that the switch is receiving a valid Fibre
Chann
el signal, but there are no upper level protocols active.1.
Verify that you are running the correct firmware on all storage
syst
em hardware.2. Check the Loop Operational LED.a. If
the L
oop Operational LED is lit, the devices have completed
init
ialization.b. If the Loop Operational LED is off, the devices
wer
e not initialized. Disconnect the devices from the switch.
Rec
onnect the devices one at a time. This allows you to i solate
the
device that is responsible for the loop failure.3. Contact your
au
thorized service representative for further assistance.
HSV controllers
This section describes the major features, p u rpose, and function of the HSV110 a nd HSV100 controllers.
Each Enterprise Virtual Array has a pair of these controllers. Figure 44 shows the HSV110 controller.
