Figure 5-14. Example connecting 2 switches to EPS ports on an HP 600 RPS/EPS

Limitations

In the illustration above, the two switches connected to the HP 600 RPS/EPS

are limited to 204 W of power on each EPS port. If a switch tries to draw more

than 204 W of power from the HP 600 RPS/EPS, an over-current condition

occurs and the EPS port connected to that switch shuts down. To supply more

than 204 W on one EPS port, the other port must first be disconnected. The

maximum power that can be provided when only one EPS port is connected

to a switch is 408 W.
