Table 10. LED status indicators for HP ProCurve Switch 5400zl series—management module
A module is installed in the switch module slot corresponding to the
letter and the module is undergoing or has passed self-test. This also
occurs when you install a module when the switch is already
powered on ("hot swap").
A module is not installed in the switch module slot corresponding
to the letter.
The module status LED flashes very briefly when a module is being
hot swapped. If the LED flashes for a prolonged time, the module in
the slot corresponding to the letter has failed self-test or
encountered some other fault condition.
PoE is normal for this slot.
The module in this slot is not a PoE module.
If any port has an internal hardware failure, blinks once every 1.6
seconds. If any port is denied PoE power or detecting an external
PD fault, blinks once every 0.5 seconds.
Indication
Flickers to show relative activity.
Flickers to show relative activity.
Indicates which ports are supplying power:
• If the Mode LED is on, the port is providing PoE power.
• If the Mode LED is off, the port is not providing PoE power.
• If the Link LED is on, the port is enabled for PoE.
• If the Link LED is off, the port is disabled for PoE.
• If the Link LED is blinking, the port has an error or the port is
denied power due to insufficient power.
Indicates speed of operation of each port:
• If the Port LED is off, the port is operating at 10 Mbps.
• If the Port LED is blinking, the port is operating at 100 Mbps.
• If the Port LED is on continuously, the port is operating at
1000 Mbps.
