Recommended Connection Topologies

UPS Support

The 600 RPS/EPS and HP 610 EPS may be used in configurations where an

Uninterruptible Power Supply (UPS) is desired. See Appendix A, “Specifica-

tions,” for the power requirements of the 600 RPS/EPS and HP 610 EPS for

use in determining your UPS requirements.

Recommendations

This section shows some recommended connection topologies using the HP

620 RPS/EPS. The HP 620 RPS/EPS can provide backup power support for up

to two switches. In the illustration below, two HP 3500yl switches are

connected to the RPS ports on a HP 620 RPS/EPS. Two HP 2900 switches can

be connected in the same way.

Limitations

The HP 620 RPS/EPS can supply power to at most two connected switches

that experience power supply failures at a time.
