EPS/RPS Operation
The EPS/RPS monitors the power signal from the switch by detecting that the
EPS/RPS is connected to a switch with an EPS/RPS cable. When the power
from the switch is no longer detected, the EPS/RPS will turn on and provide
power to the switch within 1ms.
The EPS/RPS supports hot plugging of the EPS/RPS cable without causing a
reboot of the switch or causing the power supply in either the EPS/RPS or
switch to shut down temporarily or permanently. For more information refer
to the documentation that came with the EPS/RPS.
