Dialogic SS7G21, SS7G22 1. “Backing up the System Configuration” on page, Replacing the Hardware

Chapter 9 Product Installation and Hot-Swap Actions

An SS7G20SHDD may be used in any SS7G2x Signaling Server, however, it requires a valid System License for that system. The process for making a backup of the System License and additional configuration files is described below.

Note: Only one hard disk may be used in an SS7G2x at any time. Using more than one may adversely affect system operation.

A Hard Disk Drive replacement process occurs in three stages:

1.“Backing up the System Configuration” on page 56.

2.“Replacing the Hardware” on page 56.

3.“Restoring the System Configuration” on page 57.

9.3.1Backing up the System Configuration

Before the Hard Disk Drive can be replaced, a backup of the system configuration, System License, protocol licenses and operating software must exist.

In systems running SS7G2x Software V4.04 or later, the system takes a copy of these files and stores them in the syslog subdirectory of the siuftp account at startup. These files may be recovered using FTP and archived by transferring them to an ISO9660 format CD-ROM ready for restoration at a later date.

Table 11 lists the files backed up to the syslog subdirectory at startup.

Table 11. Files Backed Up to the syslog Subdirectory at Startup

File	Type	Description
sgw.tgz	Binary	A binary file containing the current operating software on the system.
sgw.lic	ASCII	A text file containing the current software licenses active on the system,
		if present.
modcap	Binary	A binary file containing a system license allowing SS7G2x operating
		software to function on this particular system.
		A binary configuration file containing dynamically configurable data that
config.CF1	Binary	is common to all modes of operation. For example, parameters set by
		the CNSYS command would be stored in this file.
config.txt	ASCII	The text configuration file for a SIU, if present.
SDC.CF3	Binary	The binary configuration file for a SGW, if present.
SDC.CF4	Binary	The binary configuration file for a DSC, if present.

9.3.2Replacing the Hardware

WARNING

No more than one hard disk drive should be fitted in the SS7G2x. The hard disk drive should only be fitted in the left-hand Chassis slot.

Note: The diagram below shows the numbers and arrows on the right-hand Chassis slot. This is for illustration only, and the instructions to use the left-hand Chassis slot must be followed.

The steps below describe the actions required to replace the hardware. The SS7G2x must be powered-off before replacing the hardware.

1. To remove the bezel, loosen the two captive screws and lift the bezel outwards.
