Figure 21. Immediate Actions buttons
From the Home page, the following actions can be performed:
• Record Current Configuration—clicking on this button (see figure 21) saves the current configuration in
volatile DRAM memory to FLASH memory. Once the configuration is saved into FLASH memory, the
configuration will not be lost even if the power is cycled on the DACS. Initially, any changes made to the
DACS configuration are stored in volatile RAM first, enabling the user to set the box up with a working
configuration before committing it to storage in FLASH. The configuration changes become permanent
when you select Record Current Configuration.
Note If you want to save the configuration changes that you have made,
you must click on
Record Current Configuration, otherwise all con-
figuration changes will be lost if the power to the DACS is turned off.
• Hard Reset—this button (see figure 21) causes the DACS to perform a cold restart. When you select Hard
Reset, the DACS confirms that you want to execute this command. Then, the DACS will disconnect all
current sessions, re-initialize the interfaces, and re-load configuration parameters from FLASH.
• Set Factory Default Configuration—this button (see figure 21) clears out the configuration in FLASH and
loads the factory default parameters into FLASH memory. The factory default settings will not execute on
the DACS until it is re-booted by doing a Hard Reset.
Note Set Factory Default Configuration (figure 21) will delete any routing
information, the DACS’s Ethernet IP address, and any other site-specific settings made for your particular installation. You will have to reenter the DACS’s Ethernet IP address and netmask using the rear
panel control port before using the HTTP/HTML

Introduction
This chapter describes how to start or power-down the DACS.
Activating the Model 2604
Once the DACS has been installed, no operator action is required under normal conditions; the DACS is
designed for unattended operation. The DACS does not have a power switch and powers up immediately upon
connecting the power cords to the DACS. When either power supply is connected to power, the DACS will
immediately begin its boot-up cycle. However, both power supplies must be connected to power for the redundancy feature to work.
When power is applied to the DACS the following should occur:
1. The POWER LED illuminates.
2. The Link 1 Frame LED illuminates, indicating that the DACS is synchronizing with the T1/E1 signal.
3. After 5 seconds, the Link A Error LED flashes, indicating that the DACS is satisfied with the quality of the
T1/E1 signal.
4. After 10 seconds, the Link A Error LED extinguishes, indicating that the DACS is satisfied with the net-
work signal and that the link is ready for use.
5. There are two LEDs on the DACS 10/100 Ethernet port: a green LED that indicates link status and activ-
ity, and a yellow LED that indicates line speed.

Maintenance
This section describes replacing the DACS.
Replacing the DACS
If you isolate a problem to the a DACS component, the entire DACS must be replaced as follows:
Exporting the current DACS configuration
The Import/Export function enables you to make a backup (or export) copy of your access server’s configuration parameters. By exporting the configurations, the saved files can quickly be loaded (or imported) into a
replacment access server—greatly speeding up the installation process should an access server need replacing.
1. If you already have a recently exported backup of your configuration, go to “Removing the defective
DACS” on page 56.
2. To export a configuration, connect your Web browser to the Administration Pages, then click on Import/
Export under the Configuration Menu to display the Import/Export main window (see figure 30).
Figure 30. Import/Export main window
Note The parameters that will be exported are the power-up settings as
they are stored in flash memory and may not be the current operating
parameters. To ensure that you export the most current parameters,
go to
HOME, then click on the Record Current Configuration button
under
Immediate Actions.
3. To export the flash configuration, click on the
Export Flash link on the Import/Export main page. The
access server will display text configuration information resembling that shown in figure 31.
