Limitations

In the illustration above, the maximum PoE power that can be provided to the

switch is 398 watts.

UPS Support

The HP 630 RPS/EPS may be used in configurations where an Uninterruptible

Power Supply (UPS) is desired. See “Specifications,” in Appendix A for the

power requirements of the HP 630 RPS/EPS for use in determining your UPS

requirements.

Connecting Multiple HP 630 RPS/EPS units

Recommendations

The following illustration shows a topology that protects against a power

supply failure and a power main failure. By connecting one switch and one

HP 630 RPS/EPS to one power main, and by connecting the other switch and

the other HP 630 RPS/EPS to another power main, either power main can fail

without impacting the other switch.
