Setting the Device Fault Indicator

Context

If a switch is faulty, run the set device fault-light command to set the mode indicators or system indicator to the faulty state so that O&M personnel can find the faulty switch onsite.

For the S5735-S, S5735S-S, S5735-L, S5735S-L, S5735S-L-M, S5731S-H, S5732-H, S5731-S, S5731S-S, S6730-S, S6730S-S, S6720-HI, S6730-H, S6730S-H, and S6731H

When the set device fault-light under-repair command is executed, the ID indicator is steady blue and turns off after it is steady blue for the time specified by keeptime time (the default time is 45s if this parameter is not specified). The set device fault-light normal command and the undo set device fault-light command have the same functions. That is, after either of the two commands is executed, the ID indicator turns off.
For the S5720I-6X-PWH-SI-AC and S5720I-10X-PWH-SI-AC

The switch has only one fault indicator, WiFi indicator. When the set device fault-light under-repair command is executed, the WiFi indicator blinks red fast and turns off after it blinks red fast for the time specified by keeptime time (the default time is 45s if this parameter is not specified). The set device fault-light normal and undo set device fault-light commands have the same functions. That is, after either of the two commands is executed, the WiFi indicator turns off.
For the S5735-S-I

The switch has only one fault indicator, SYS indicator. When the set device fault-light under-repair command is executed, the SYS indicator blinks red fast and turns off after it blinks red fast for the time specified by keeptime time (the default time is 45s if this parameter is not specified). The set device fault-light normal and undo set device fault-light commands have the same functions. That is, after either of the two commands is executed, the SYS indicator turns off.
For other switches that support this command

When the set device fault-light under-repair command is executed, the SYS indicator and mode indicators (STAT, SPED, PoE, and STCK) blink red fast. After these indicators blink red fast for the time specified by keeptime time (the default time is 45s if this parameter is not specified), the SYS indicator returns to the previous state, and the STAT indicator is steady on.

The set device fault-light normal and undo set device fault-light commands have the same functions. That is, after either of the two commands is executed, the SYS indicator returns to the previous state, and the STAT indicator is steady on.

If slot slot-id is not specified in a stack, the configuration takes effect on indicators on the master switch.

S5720-HI does not support this function.

Procedure

Run system-view
The system view is displayed.
Run set device fault-light { normal | under-repair [ keeptime time ] } [ slot slot-id ]
The fault indicator status of the device is set.

By default, the fault indicator status of the device is not set. The fault indicator status is displayed based on the current device running status. If not slot ID is specified in a stack, this command sets the fault indicator status of the stack master.

normal indicates that the fault indicator status is displayed based on the current device running status. under-repair configures the fault indicator to indicate that the device is faulty. If keeptime time is not specified, the default time during which the fault indicator indicates that the device is faulty is 45 seconds.
(Optional) Run display device fault-light
The fault indicator status is displayed.
