Chassis Status LEDs on EX4000 Switches
EX4000 switches have three chassis status LEDs (labeled SYS, MST, and CLD) on the front panel.
1 — Chassis status LEDs |
Table 2 describes the system chassis status LED labeled as SYS on an EX4000 switch when in standalone mode.
LED Label | Color | State and Description |
|---|---|---|
SYS | Blinking green | Switch is booting up. |
Solid green | Switch has booted up. No alarms. | |
Amber | Minor Alarm | |
Red | Major Alarm | |
Blue | Apperas on short press of Pin Hole Reset button. See Revert to the EX Series Switch Factory-Default Configuration or Zeroize the Switch Using Pin Hole Reset Button. | |
Purple | Appears on long press of Pin Hole Reset button. See Revert to the EX Series Switch Factory-Default Configuration or Zeroize the Switch Using Pin Hole Reset Button. |
Table 3 describes the chassis status LED labeled MST when the switch is in standalone mode.
You can view the colors of the LEDs remotely through the CLI by issuing the
show chassis led operational mode command.
LED Label | Color | State and Description |
|---|---|---|
MST | Green | In a standalone switch:
