Power over Ethernet (PoE) Commands
520
ProSafe Managed Switch
no poe detection
Use this command to set the detection mode to the default on a global basis or per interface.
poe high-power
Use this command to switch a port from 802.3af mode to high-power mode. This mode is used to
power up devices that require more power than the current IEEE 802.3af power (more than
12.95 watts at the PD). There are three options:
• legacy—Use this mode if the device can power up (more than 12.95 watts) with higher
current and it cannot identify itself as a Class 4 device.
• Pre-dot3at—Use this mode if the device cannot identify itself as a Class 4 device and it
does not have LLDP support.
• Dot3at—Use this mode if the device is a Class 4 device capable of figuring out power
requirements through 2-event classification or LLDP.
no poe high-power
Use this command to disable the high-power mode. The port will support only IEEE 902.3af
devices.
This command works on a global basis or per interface.
poe power limit
Use this command to configure the type of power limit for a port. If the power limit type is
“user-defined,” the command also allows you to configure a maximum power limit.
There are three options:
• class-based—Allows the port to draw up to the maximum power based on the
classification of the device connected.
• none—Allows the port to draw up to Class 0 maximum power if it is in low-power mode
and up to Class 4 maximum power if it is in high-power mode.
