IP TELEPHONY AND USER-MOBILITY SUPPORT WITH CISCO CATALYST 6500 SERIES 10/100 AND 10/100/1000 ETHERNET
INTERFACE MODULES
The Cisco Catalyst 6500 Series is a lead element in Cisco AVVID, providing numerous IP telephony and network security features for the enterprise.
The Cisco Catalyst 6500 Series delivered the industry's first Ethernet switching modules that provided PoE for converged data and voice traffic as
well as other powered devices, such as wireless access points. Several Cisco Catalyst 6500 Series interface modules support PoE on each interface
port, allowing customers to build campus multiservice data and voice networks for wiring closets with the following features:
•
PoE—Provides power for Cisco Prestandard Inline Power and IEEE 802.3af standard PoE over standard Category 5 UTP cable up to 100 meters
for such as IP phones and wireless access points
•
Powered Device Discovery—Detects the presence of a powered device such as an IP phone and supplies inline power automatically
•
Auxiliary VLAN using 802.1Q—Segments IP phones and data endpoints into separate, logical networks automatically
•
Automatic quality of service (AutoQoS)—Simplifies the task of configuring QoS mechanisms for IP telephony and more
•
Cisco Identity Based Networking Services (IBNS)—Enables greater security while simultaneously offering cost-effective management of changes
throughout the organization
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.)
