●
Maximum port density per chassis: These modules support up to 1152 10/100 ports
or 576 10/100/1000 ports in the Cisco Catalyst 6513 chassis; up to 768 10/100 ports or
384 10/100/1000 ports in the Cisco Catalyst 6509 chassis; up to 480 10/100 ports or 240
10/100/1000 ports in the Cisco Catalyst 6506 chassis; and up to 192 10/100 ports or 96
10/100/1000 ports in the small-form-factor Cisco Catalyst 6503 chassis.
●
Field-installable and -upgradable inline-power daughter cards: These modules help
enable centralized power distribution to IP phones, wireless access points, and other
devices by sharing the same Category 5 UTP cabling used for network connections.
Note: Some of these modules are designed to support field upgrades to the IEEE 802.3af PoE
standard with a new daughter card, providing maximum investment protection. Table 6 for details.
●
TDR: TDR is supported in all the 10/100/1000 modules and 10/100 modules (product
numbers WS-X6148A-RJ-45 and WS-X6148A-45AF); TDR tests cabling by sending
signals down the cable to identify faults in each twisted pair.
