active PoE port - PoE-enabled port connected to a PD request power.
priority class - Refers to the type of power prioritization where the switch
uses Low (the default), High, and Critical priority assignments to determine
which groups of ports will receive power. Note that power priority rules apply
only if PoE provisioning on the switch becomes oversubscribed.
EPS - External Power Supply
PD - Powered Device. This is an IEEE 802.3AF-compliant device that receives
its power through a direct connection to a 10/100Base-TX PoE RJ-45 port on
the switch. Examples of PDs include Voice-over-IP (VoIP) telephones, wire-
less access points, and remote video cameras.
port-number priority - Refers to the type of power prioritization where,
within a priority class, the switch assigns the highest priority to the lowest-
numbered port, the second-highest priority to the second lowest-numbered
port, and so-on. Note that power priority rules apply only if PoE provisioning
on the switch becomes oversubscribed.
PoE - Power-Over-Ethernet
PSE - Power-Sourcing Equipment. A PSE, such as a Switch 2626-PWR or 2650-
PWR, provides power to IEEE 802.3AF-compliant PDs directly connected to
10/100Base-TX PoE RJ-45 ports on the switch. The Switch 2626-PWR and 2650-
PWR are endpoint PSEs.
