Figure 25 Example of setting a time and duration for savepower led command
Configuring the savepower port-low-pwr option
The port-low-pwr option puts the slots into auto low power mode if they are not linked. If a
particular slot is specified, only that slot goes into auto low-power mode. Specifying savepower
port-low-pwr all puts all the slots into auto low power mode. (See Figure 26 (page 144).)
The ports in low-power mode periodically monitor to determine if the link has become active. If a
LAN cable is connected to one of the ports, that port will come out of the low-power mode state
after approximately 2 seconds (the monitor period) and enter into normal power mode. The
remaining ports continue to be in low-power mode.
The no form of the command puts the specified slot into normal power mode. Entering no
savepower port-low-pwr all puts all the slots into normal power mode.
