• Phone discovery—Automatically detects the presence of an IP phone and
supplies inline power to the phone.
• Auxiliary VLANs—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.
The QoS port architecture (Rx/Tx) for this module is 1q4t/2q2t.

48-Port 10/100BASE-T Ethernet Switching Module
(WS-X6148-RJ21V)
The 48-port 10/100BASE-T switching module (WS-X6148-RJ21V) provides 48
switched, 10/100-Mbps autosensing, full- or half-duplex ports. (See Figure 1-7.)
The module has 4 RJ-21 connectors (12 ports per connector) 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 these IP phone features on each port:
• Inline power—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.
• Phone discovery—Automatically detects the presence of an IP phone and
supplies inline power to the phone.
