LEDs
As shown in Figure 1-1 and Figure 1-2 , the PA-VXAs have three LEDs on the faceplates; a green
enabled LED, a bicolor alarm LED, and a bicolor port status LED. Table 1-1 lists the colors and
functions of the LEDS.
As shown in Figure 1-3 and Figure 1-4 , the PA-VXB and PA-VXC port adapters have four LEDs on the
faceplate: a green enabled LED, a bicolor alarm LED, and two bicolor port status LEDs, one for each
port.
Table 1-1 lists the colors and functions of the LEDs.
Cables, Connectors, and Pinouts
The T1/E1 interface receptacles on the PA-VXA, PA-VXB, and PA-VXC port adapters are for RJ-45
connectors for both T1 (100 ohm) and E1 (120 ohm).
After you properly connect a port to a line, it takes approximately 30 seconds for the Cisco IOS to report
that the line is up.
Each connection supports T1(100-ohm) or E1(120-ohm) interfaces that meet T1.403 and ACCUNET
TR62411 standards. The RJ-45 connection does not require an external transceiver. The DS1 ports are
T1 interfaces that use foil twisted-pair cables.
Shielded cables (foil twisted-pair [FTP]) with 120-ohm impedance are required to comply with CE
marking requirements.
Figure 1-5 shows the PA-VXA, PA-VXB, and PA-VXC port adapter interface cable connector. See the
“Connecting Interface Cables” section on page 3-15 for directions on connecting the cables to a
PA-VXA, PA-VXB, or PA-VXC.
