14 Introduction
Introduction
You may configure the access server by using its internal HTTP/HTML Administration Pages. However, to
enter into the HTTP/HTML pages, you must first define the LAN Address Technique, LAN IP Address, and
LAN Subnet Mask for the access server. If you have not done so, please refer to the Getting Started Guide that
came with your access server.
Logging into the HTTP/HTML Administration Pages
To log into the HTTP/HTML Administration pages, you must enter the 4-octet Internet Protocol (IP) (for
example, http://your.server.ip.address ) address as the Universal Resource Locator (URL) into a World-Wide Web
(WWW) browser. After you enter the IP address, the access server will ask for your user name and password as
shown in figure 1.
Figure 1. Access server login window
Your access server will accept the following default administrative passwords:
•superuser—this password carries full permission to change and view any parameters in the access server
•monitor—this password allows full viewing of any non-password oriented variables.
Note
For security reasons, we recommend that you change these passwords
immediately after initial configuration.
HTTP/HTML and SNMP Object Format
In this document, we shall describe the variables found on each of the internal HTTP/HTML pages. This
description will include brief definitions of the Patton Enterprise MIB or SNMP MIB II object identifiers
wherever applicable. The format of the variables will resemble figure 2.
Figure 2. HTTP/HTML and SNMP object format

Saving HTTP/HTML Object Changes 15
Model 3120 RAS Administrators’ Reference Guide 1 • Introduction
Saving HTTP/HTML Object Changes
Sometimes you will need to save changes that you have made in the HTTP/HTML pages. Do the following to
make changes to read/write variables:
1. Select the appropriate
Modify
screen.
2. Make changes to the desired parameter.
3. Click on the
Submit
button.
4. Return to the HOME screen.
5. Click on the Record Current Configuration button.
Note Make sure you follow steps 1 through 5 when modifying the HTTP/
HTML pages. Otherwise, your changes will be lost when the access
server is power-cycled.

18 Introduction
Introduction
This chapter describes the HOME window—the first Administration Page that you see after logging into the
access server (see figure 3). From HOME, you can monitor current system status, modify the Static User data-
base, save any system changes, or reset the system without power-cycling the server.
Note Clicking on the HOME link in the Configuration Menu pane will
return you to the HOME page from any other page.
The HOME window is divided into two panes: the Configuration Menu pane and the configuration/information
pane (see figure 3). The Configuration Menu contains the links to the various access server subsystems, while
the configuration/information pane is where you can view status and other information, or make changes to
the system configuration. Unlike the Configuration Menu pane, which looks the same no matter which sub-
system page you may move to, the configuration/information pane contents will change as you move from one
subsystem page to another.
Figure 3. HOME page

Operating Status Variables 19
Model 3120 RAS Administrators’ Reference Guide 2 • Home
Operating Status Variables
There are seven system variables which describe the immediate operating status access server. These variables
are shown in figure 4 and are described in the following sections.
Figure 4. STATUS menu
Active Calls (diActive)
This number, ranging from 0 to 120 displays the total number of calls being processed (connecting, online,
authenticating, and so on) in the access server at the time the HOME page was displayed.
Peak Active Calls (diMaxActive)
The maximum number of active calls seen at one time since the access server was powered on.
Total Calls (diTotalCallAttempts)
The total number of calls attempted since the last boot of the box.
DSPs Not Working (dspFailed)
This number should always be zero. The DSPs in the access server are arranged as a resource pool and called
upon at ring-time. If a DSP fails to respond to the access server’s CPU, it is determined to have failed, at which
point the CPU will remove the DSP from the resource pool. If an incoming call attempts to access the failed
DSP, the RAS will answer, then terminate the call (to a person monitoring the failed call through a telephone
handset, he or she will hear only silence during the call, ending with a faint click as the call is terminated). One
symptom indicating that a DSP has failed is if the access server is not handling as many calls as it normally does.
Total DRAM Detected (boxDetectedMemory)
This number shows the total number of bits of installed and available DRAM.
Running Since Last Boot (sysUpTime)
This tells you how long the access server has been running since the it was last reset. It displays the number of
hours and rolls over after 1,193 hours (497 days).

20 Immediate Actions
Immediate Actions
There are several immediate actions (see figure 5) which, when in superuser mode, will cause the access server
to operate according to the descriptions in the following sections.
Figure 5. Immediate Actions buttons
•Record Current Configuration —clicking this button causes the current configuration to be stored in
FLASH memory. Any changes made to the access server configuration are stored in non-volatile RAM. This
allows the user to set the box up with a running configuration before committing it to FLASH. Configura-
tion changes become permanent when you select Record Current Configuration. You will lose all
changes not stored to FLASH the next time the access server is re-booted.
•Hard Reset—this button causes the access server to perform a cold restart. When you select Hard Reset,
the access server confirm that you want to execute this command. Then, the access server will disconnect all
current sessions, re-initialize the interfaces, and re-load configuration parameters from FLASH.
•Set Factory Default Configuration—this button clears out the configuration in FLASH and loads the
factory default parameters into FLASH memory. The factory default settings will not execute on the access
server until it is re-booted.
Note Set Factory Default Configuration will delete any routing infor-
mation, the access server’s Ethernet IP address, and any other site spe-
cific settings made for your particular installation. You will have to re-
enter the access server’s Ethernet IP address and netmask using the
front panel control port in order to use the HTTP/HTML Manage-
ment pages.
