Cisco Catalyst Prestandard Inline Power and IEEE 802.3AF POE
Using existing Category 5 UTP installations, the PoE feature helps enable network administrators
to control power distribution from a central location. Configuring Cisco Catalyst 6500 Series
switches with uninterruptible-power-supply (UPS) systems helps ensure that building power
outages will not affect network telephony connections, providing greater network availability.
Enabled by a daughter card for "pay-as-you-grow" flexibility, several Cisco Catalyst 6500
Series 10/100 and 10/100/1000 Ethernet interface modules support PoE. Some of these interface
modules support the IEEE 802.3af standard as an additional upgrade option. The Cisco Catalyst
PoE feature implementation passes the required domestic and international safety regulations
and compliance measures.
All Cisco Catalyst 6500 Series 802.3af PoE modules support all three classes of powered devices,
delivering a maximum of 15.4W per port as defined in the standard:
Class 1: Up to 4W per port
●
Class 2: Up to 7W per port
●
Class 3: Up to 15.4W per port
●
All 802.3af PoE modules are capable of supporting up to 48 Class 3 devices per module (that is,
15.4W per port for 48 ports simultaneously). The maximum number of powered devices supported
in a system for each class depends on the specific system configuration such as chassis type,
supervisor engine, and power supply used. (Refer to Table 1.)
