Description
This is the stack member ID (1–8) that the software assigns to the switch.
• Solid green: The power module is present, is supplying power to the switch, and
is operating normally.
•
Solid yellow: The system is in boot-up stage.
•
Blinking yellow: POS/ CPU system has failed.
•
Off: Power is disconnected.
• Solid green: The fan is operating normally.
• Solid yellow: The fan has failed.
• Off: No fan is detected.
•
Solid green: The redundant power supply is connected and drawing power form
the power module.
•
Solid yellow: The power module has failed or been disconnected, but the
redundant power supply is providing power to the switch.
•
Blinking yellow: The redundant power supply is present but the power has
failed.
•
Off: The redundant power supply is disconnected or is not present.
• Green: The switch is a master unit in a stack of GSM7200PS series switches.
• Off: The switch acts as a slave unit in a stack of GSM7200PS series switches.
•
Solid yellow: Indicates less than 7W of PoE power is available.
•
Blinking yellow: Indicates the PoE MAX LED was active in the previous 2
minutes.
• Off: There is at least 7W of PoE power available for another device.
•
Off: No module is present or a module is present but is not linked with the
system.
•
Solid green: A module is present and linked up with the system.
•
Blinking green: The port is transmitting or receiving packets.
SPD/Link/ACT LED:
•
Off: No link is established on the port.
•
Solid green: A valid 1000 Mbps link is established on the port.
•
Blinking green: The port is transmitting or receiving packets at 1000 Mbps.
• Solid yellow: A valid 10/100 Mbps link is established on the port.
• Blinking yellow: The port is transmitting or receiving packets at 10/100Mbps.
PoE Status LED:
•
Off: No PoE powered device (PD) is connected.
•
Solid green: The PoE powered device (PD) is connected and the port is
supplying power.
•
Solid yellow: Indicates one of the following failures resulted in stopping power to
that port:
– Short circuit on PoE power circuit.
– PoE power demand exceeds power available.
– PoE current exceeds PD's classification.
– Out of correct voltage band (44 ~ 57 VDC for af, 50~57 VDC for at).
