Table 1-3. GSM7252PS LED Description
LED Description
ID This is the stack member ID (1–8) that the software assigns to the switch.
Power
•
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.
Fan
•
Solid green : The fan is operating normally.
• Solid yellow : The fan has failed.
•
Off : No fan is detected.
RPS
(redundant power
supply)
•
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.
Stack Master
•
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.
PoE Max • 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.

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).
