PoE Overview

Model MS510TXPP supports both IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) on ports
1–8 with a maximum PoE power budget of 180W across all active PoE+ ports. You can
globally specify the following:
• Limit port power based on the PD class or on user settings.
• Allow detection of both standards (802.3af and 802.3at)–based and legacy
(pre-standard)–based PDs.
• Allow detection only of standard-based PDs.
• Enable or disable PoE related traps.
The power limit of a port is based on the global setting of the power limit type. If the power
limit type is based on the PD class, the port limit is based on the class that is advertised by
the PD attached to the port. If the power limit type is based on the user settings, the port limit
is based on the maximum power limit that you configure for the port (the default is 30W).
On a per-port basis, you can enable or disable PoE and configure priority settings, timers,
and power limits. Doing so allows you to manage the power supplied to the connected PDs
and to ensure that the power budget is used effectively.
By default, supplied power is prioritized on the switch in ascending port order, up to the total
power budget of the switch. If the power requirements for the attached PDs exceed the total
power budget of the switch, the power to the device on the highest-numbered PoE+ port is
disabled to make sure that the devices connected to the higher-priority, lower-numbered
PoE+ ports are supported first.
Note: Although a device is listed as an 802.3at (PoE+) powered or 802.3af
(PoE) powered device, it might not require the maximum power limit
that is specified. Many devices require less power, allowing all eight
PoE ports to be active simultaneously, when the devices correctly
report their PoE class to the switch.
Device Class Power Requirements
PoE and PoE+ use Ethernet cables to supply power to PoE-capable devices on the network,
such as WiFi access points, IP cameras, VoIP phones, and switches. The switch is compliant
with the IEEE 802.3at standard (PoE+) and backward compatible with the IEEE 802.3af
standard (PoE). The switch can pass power through to any powered device (PD) that
