Question Answer
What is the difference between a UPS and an RPS? A UPS (Uninterruptible Power Supply) is an external
power backup device. The UPS serves as a battery
backup, so that if your AC power source fails (as in a
brownout or blackout), the UPS will still provide power. To
order an HP UPS, call 1-800-538-8787.
An RPS (Redundant Power Supply) is an external power
backup device. The power supply of the RPS is duplicated
(redundant) of the Switch 2000, so that if one power supply
component fails the RPS will still provide power.
Should I keep my device’s AC power cord connected? Yes. Otherwise, you do not have redundant power.
Do I have to plug both AC power cords into different AC
power sources? We recommend that you connect each AC power cord to
a different AC power source but it is not required.
