REFURB CAT6500 48 PT 10/100 INLINE PWR RJ-45 The 48-port 10/100BASE-T switching module (WS-X6148-RJ45V) provides 48 switched 10/100-Mbps autosensing full- or half-duplex ports. The module has 48 RJ-45 connectors for use with either Category 3 Category 5 Category 5e or Category 6 UTP cable. The V in the product number indicates that the inline-power daughter card (WS-F6K-VPWR) is installed on the module. With the WS-F6K-VPWR daughter card installed the module provides 48 VDC over standard Category 5 Category 5e or Category 6 UTP cable up to 328 feet (100 meters) from the switch to the IP phone. With inline power pairs 2 and 3 (pins 1 2 3 and 6) of the four pairs in the cable are used to transmit power (6.3 W) from the switch. This method of supplying power is sometimes called phantom power because the power signals travel over the same two pairs used to transmit Ethernet signals. The power signals are completely transparent to the Ethernet signals and do not interfere with their operation. Automatically detects the presence of an IP phone and supplies inline power to the phone. Provides automatic VLAN configuration for IP phones using IEEE 802.1Q as the standards-based VLAN tagging mechanism between the switch and the IP phone.
