PA-8T-V.35 Synchronous Serial Port Adapter Installation and Configuration

OL-3563-03

Chapter 1 Overview

LEDs

Note V.35 supports 2.048-Mbps rates without any problems; we do not recommend exceeding the above

specifications for transmission speed versus distance. Do so at your own risk. The total aggregate

bandwidth for the PA-8T-V.35 is 16 Mbps, which can be divided into 8 Mbps on two ports; 4 Mbps on

four ports; or 2 Mbps on eight ports.

LEDs

The PA-8T-V.35 has one row of eight status LEDs (one for each port) and one enabled (EN) LED. (See

Figure 1-2.) The green- and amber-colored LED for each port indicates port status.

Figure 1-2 LEDs on the PA-8T-V.35 Port Adapter—Horizontal Orientation

After system initialization, the enabled LED goes on to indicate that the port adapter has been enabled

for operation.

The following conditions must be met before the PA-8T-V.35 is enabled:

• Port adapter is correctly connected to the backplane or midplane and receiving power.

• Valid system software image for the port adapter has been downloaded successfully.

• System recognizes the port adapter or PA-8T-V.35-equipped VIP, Catalyst RSM/VIP2,

Catalyst 6000 family FlexWAN module, or Cisco 7304 PCI Port Adapter Carrier Card.

If any of the above conditions are not met, or if the initialization fails for other reasons, the enabled LED

does not go on.

Table 1-2 lists port LED colors and indications.

serial cable is properly connected at the router

end and the network end.

mode (Cisco 7200 series routers only).
