Power module failure
You can look at the PWR1 or PWR2 LED on the front panel of the switch and the LEDs on the power
module to identify a power module failure.
• For more information about the PWR1 and PWR2 LEDs on the front panel of the switch, see Table
9 .
• For more information about the LEDs on a hot swappable power module, see H3C PSR300-12A &
PSR300-12D Series Power Modules User Manual, H3C LSVM1AC650 & LSVM1DC650 Power
Modules User Manual, and H3C LSVM1AC300 & LSVM1DC300 Power Modules User Manual.
NOTE:
The S5820X-26S switch does not provide the PWR1 or PWR2 LED, and you use the LEDs on the power
modules to identify power supply problems.
