Caution
Seul le système d'alimentation redondant Cisco (RPS modèle PWR600-AC-RPS) doit
servir à alimenter le dispositif externe.
Das externe Gerät darf nur mit einer redundanten Stromversorgung von Cisco, Modell
PWR600-AC-RPS, betrieben werden.
Para alimentar el dispositivo externo, usar exclusivamente el sistema de alimentación
redundante (redundant power system = RPS) Cisco, modelo PWR600-AC-RPS.
Overview
The Cisco RPS provides power system redundancy to external devices (such as routers,
switches, or hubs). The system includes two fully redundant AC input power modules and
four DC output power modules for connection to external devices. The Cisco RPS supports
the following power source configurations: quasi-redundant and fully redundant.
Quasi-Redundant Power
The Cisco RPS can provide a quasi-redundant power source for up to four external devices
that use 150W or less each. You can use a one-to-one cable (one connector at each end of
the cable) to connect up to four external devices to the four DC output power modules, as
shown in Figure 1-5. When using one-to-one cables, the power source is quasi-redundant
because there are two AC input power modules for the Cisco RPS and one DC power output
module for each external device. The AC input to the Cisco RPS is fully redundant, but the
DC output to the external devices is not.
Figure 1-5
Use the Cisco RPS (model PWR600-AC-RPS) only to power the external device.
