Usage Guidelines
When using a Cisco Power Device, the delay shutdown command is not needed. Although you can
configure a delay shutdown time, it does not take any action on a connected Cisco device.
The delay shutdown command is only recommended for certain IEEE Power Devices that require
multiple reloads during initialization. Use the delay shutdown seconds initial seconds keywords to
configure the switch to continue providing power during initialization. Without using the delay
shutdown command, the switch removes power immediately when linkdown occurs on the connected
device.
Caution To avoid product damage, you should not connect any non-IEEE Power Device during the delay
shutdown time interval. When the delay shutdown command is active on a port, the port remains
powered after unplugging the IEEE Power Device for the configured time interval.
