Identifying Port Adapter Slot and PA-4T+ Interface Port Numbers
PA-4T+ Synchronous Serial Port Adapter Installation and Configuration8-2
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket
(>). At the console terminal, use the following procedure to enter the privileged level:
Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for
a privileged-level password as follows:
Router> enable
Password:
Step 2 Enter the password (the password is case-sensitive). For security purposes, the password
is not displayed.
When you enter the correct password, the system displays the privileged-level system
prompt (#):

Identifying Port Adapter Slot and PA-4T+ Interface Port Numbers
This section describes how to identify port adapter slot and PA-4T+ interface port numbers for the
Cisco 7100 series, Cisco 7200 series, the Cisco uBR7200 series routers, and the VIP2.
Cisco 7200 Series and Cisco uBR7200 Series Ports
Physical port addresses specify the actual physical location of each interface port on a Cisco 7200
series router (see Figure 8-1) or a Cisco uBR7200 series router (see Figure 8-2). This address is
composed of a two-part number in the format port adapter slot number/interface port number, as
follows:
• The first number identifies the chassis slot in which the PA-4T+ is installed.
• The second number identifies the interface ports on each PA-4T+, which are always numbered in
sequence as interface 0 through 3.
Interface ports on the PA-4T+ maintain the same address regardless of whether other port adapters
are installed or removed. However, when you move a port adapter to a different slot, the first number
in the address changes to reflect the new slot number.
In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right,
beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202,
slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR.
Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present.
Figure 8-1 shows the interface ports of a PA-4T+ in slot 1 of a Cisco uBR7246 router.
For example, the addresses of the interface ports on the PA-4T+ in chassis slot 1 are 1/0 through 1/3
(chassis slot 1 and interface ports 0 through 3). If the PA-4T+ was in port adapter slot 4, these same
interface ports would be numbered 4/0 through 4/3.
