Power Over Ethernet (Poe) Commands - NETGEAR ProSafe GSM7228PS Cli Manual

Most vendors today implement the PSE technology outside of the existing switch, a technique
called a midspan solution. AVAYA and Cisco also implement this technology inside the switch,
called an end-span solution.
Attached to the PSE is the UPS. A UPS is connected to each device that requires alternative power.
With Power over Ethernet, this function is centralized in a UPS connected to the PSE. Note that
this may require further changes in the environmental conditions of the room needing to support
this UPS with all of its electrical and cooling requirements.
The current delivered to each node is limited to 350 milliamps. The total amount of continuous
power that can be delivered to each node, taking into account some power loss over the cable run,
is 12.95 watts. IP phones and wireless LAN access points typically consume 3.5 to 10 watts.
Power is carried on two wire pairs, to comply with safety standards and existing cable limitations.
Management may also be added to monitor and control the PSE. This management function may
be integrated into a standard network management platform using the simple network management
protocol (SNMP) or through a custom platform. Beyond the basic control of the PSE, the
management station provides additional power management functions, like power quality of
service (QoS) where key users are given higher priority to power in the event of a outage.
Voice-over IP (VoIP), is the transmission of telephone calls over a data network like one of the
many networks that make up the Internet.

Power Over Ethernet (PoE) Commands

This section shows the additional CLI commands required to provide the management interface to
the Power-over-Ethernet (PoE) function. These commands only apply to GSM728PS and
GSM7252PS switches.
Note: For the GSM7228PS, only ports 1-24 are support the PoE function. For the GSM7252PS,
only ports 1-48 support the PoE function.
