Troubleshooting PSR750-D failures
When the power supply system functions normally, the corresponding power module LEDs should be
steady green. Otherwise, check whether
1) The RPS1000-A3 is adopted as the power supply.
2) The two module slots on the RPS1000-A3 are both inserted with a power module, and both
modules of the RPS1000-A3 work normally.
3) RPS power cords of H3C are used to connect the switch to the RPS1000-A3.
4) Two lines are connected between the PSR750-D and the RPS1000-A3 with RPS power cords of
H3C.
5) The positive (+) and negative (-) ends on the RPS power cords are correctly connected to the
PSR750-D, and the RPS power cords is well connected.
6) The RPS power cords are well connected to the outputs OUTPUT1 and OUTPUT2 on the
RPS1000-A3.
7) The reset buttons of OUTPUT1 and OUTPUT2 on the rear panel of RPS1000-A3 are in normal
state, as shown in
Figure 6-1
. (Normally, the reset buttons of OUTPUT1 and OUTPUT2 are
pressed down. If OUTPUT1 or OUTPUT2 enters the protection state due to over current, the
corresponding reset button is lifted up automatically. After solving the over-current problem, press
the reset button. Then the corresponding power output becomes normal.)
8) The operating temperature of the switch is normal and proper ventilation is ensured for the power
module.
9) The operating temperature of the RPS1000-A3 is normal and proper ventilation is ensured for the
RPS1000-A3.
