 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.
