Section 2 Commissioning the Cisco AS5300 Hardware
Verifying Basic Setup
Figure 2-1 shows the following:

Client modems and ISDN routers dial into the access server through the PSTN.

Analog PPP calls connect to modems inside the access server.

Each modem inside the access server provides a corresponding TTY line and asynchronous
interface for terminating character and packet mode services.

Asynchronous interfaces clone their configurations from a group-async interface.

Synchronous PPP calls connect to serial interface channels (for example, S0:1 and S0:2).

Synchronous interfaces clone their configurations from a dialer interface.
One analog PPP call consumes:

One T1 DS0 channel

One channel in a TDM bus

One integrated modem

One TTY line

One asynchronous interface
One synchronous PPP call consumes:

One T1 DS0 channel

One serial interface channel
Task 1. Verifying Basic Setup
The following subsections detail the tasks required to verify that basic system components are
functioning normally:

1.1 Analyzing the System Boot Dialog

1.2 Checking the Initial Running-Config

1.3 Exploring the Cisco IOS File System

1.4 Investigating Memory Usage

1.5 Inspecting CPU Utilization
1.1 Analyzing the System Boot Dialog
The Cisco AS5300 has a specific boot sequence. To view the boot sequence through a terminal session,
you must have a console connection to the access server before it powers up.
The following boot sequence occurs. Event numbers and comments are inserted in the example to
describe the boot sequence.
