Table 15 30-10010-02 loop switch port status indicators
DescriptionPort bypass indicator
(Amber)
SFP status
indicator (Green)
Indicates that the port does not have an SFP installed and is bypassed
by the loop.
OffOff
Indicates that the port is operating normally. The port and device are
fully operational.
OffOn
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.
OnOn
Indicates a Tx fault. The port is non-operational due to an SFP transmitter
fault, improperly-seated SFP, or another failed device.
OnOff
Problem isolation
Table 16 (page 47) lists several basic problems and their solutions.
Table 16 30-10010-02 loop switch basic troubleshooting
Recommended actionProblem
1. Verify that the power cord is firmly seated in the switch and is
connected to the power outlet.
2. Check the power indicator to verify that the switch is on.
SFPs are installed in ports but no indicators
are lit.
Re-seat the SFP. If the same condition occurs, the SFP is probably faulty
and should be replaced.
SFP is installed, but the Port Bypassed
indicator is 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 powered on.
2. Contact your HP authorized service representative for further
assistance.
SFP is installed, but the SFP status indicator
and the Port Bypassed indicator are lit.
This condition indicates that the switch is receiving a valid Fibre Channel
signal, but there are no upper level protocols active.
1. Verify that you are running the correct firmware on all storage system
hardware.
2. Check the Loop Operational indicator.
a. If the Loop Operational indicator is lit, the devices have completed
initialization.
b. If the Loop Operational indicator is off, the devices were not
initialized. Disconnect the devices from the switch. Reconnect the
devices one at a time. This allows you to isolate the device that
is responsible for the loop failure.
3. Contact your authorized service representative for further assistance.
SFP is installed and the SFP status indicator
is lit, but the devices are not communicating.
HSV controllers
Two controllers (HSV210-A/B or HSV200-A/B) are contained in each rack. Each controller is
contained in a separate controller and provides the following features:
• High-performance microprocessor
• An Operator Control Panel (OCP)
