active PoE port -
delivering 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 -
PD
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
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
PSE
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, 2650-
PWR and the Switch xl PoE Module are endpoint PSEs.
