DC Power Supply LEDs on a QFX3500, QFX3600, or QFX3600-I Device
Figure 1 shows the location of the LEDs on the DC power supply.

1 — Shunt positive input terminals | 5 — ESD grounding point |
2 — Shunt negative input terminals | 6 — Fault LED |
3 — Terminal block | 7 — Output LED |
4 — Ejector lever | 8 — Input LED |
The V+ terminals are shunted internally together, as are the V- terminals. The same polarity terminal can be wired together from the same source to provide an additional current path in a higher power chassis. Do not connect the terminals to different sources.
Table 1 describes the LEDs on the DC power supplies.
