Table A3: LED status indicators for HP ProCurve Switch 5400zl series—management modules (continued)
LED State Indication
PoE On (green) If any PoE modules are installed.
Off If no PoE modules are installed.
Blinking (orange) Internal PoE fault, external load fault, or denied PoE power.
Temp On Internal temperature is normal.
Blinking (orange) An over-temperature condition has been detected.
Fan On (green) Normal operation.
Blinking (orange) One or more of the switch’s fans have failed. The switch Fault LED will be blinking simultaneously.
Internal Power
(numbers
corresponding to
the power supply
positions)
On (green) A power supply is installed in the position in the back of the switch corresponding to the number, and
the supply is plugged in to an active AC power source. As shipped, the switch has a single power
supply in position 1.
Off A power supply is not installed in the position corresponding to the number.
Blinking (orange) The power supply installed in the position corresponding to the number is not plugged in to an active
AC power source, or has experienced a fault. The switch Fault LED will be blinking simultaneously.
EPS On (green) An external power supply is connected.
Off An external power supply is not connected.
Blinking (orange) The external power supply has a fault, or is connected but not plugged in to AC power.
Modules
A, B, C, D, E, F, G,
H, I, J, K, L
On (green) 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”).
Off A module is not installed in the switch module slot corresponding to the letter.
Blinking (orange) 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.
Modules in PoE
Mode
On (green) PoE is normal for this slot.
Off The module in this slot is not a PoE module.
Blinking (orange) If any port has an internal hardware failure, it blinks once every 1.6 seconds. If any port is denied PoE
power or detecting an external PD fault, it blinks once every 0.5 seconds.
LED Mode Select Act (green) Flickers to show relative activity.
FDx (green) Flickers to show relative activity.
PoE (green) 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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.
Spd (green) 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.
