3.3.3. Installation
The following procedure is executed :
1. The ISG is powered up and the internal boot package is activated.
2. The ISG issues a DHCP request for an IP address on the network. If the DHCP server fails,
then go to step 7.
3. The DHCP server should supply the (fixed) IP address info together with the address of
the TFTP server, if it fails then go to step 7.
4. The ISG issues a request to the TFTP server and asks for the file prebisg.txt. When found
the file prebisg.txt is sent to the ISG, which reads the file name of the application package.
If it fails, then go to step 7.
5. The ISG checks if the received file name of the application package differs from the current
loaded application package, if so continue at the next step, else continue at step 7.
6. The ISG issues a request to the TFTP server and asks for the file of the SW application
package. The file with the compressed SW application (=operational) package is loaded.
7. The ISG checks if a compressed SW application is stored in its memory if it is the case the
ISG decompresses the SW application package and loads it into the working memory. If it is not present then reboot.
8. The ISG will start the SW application (= operational) package.
9. The ISG reports a "board present" signal to the iS3000.
10. The ISG will wait for the "in service" command sent by the iS3000 via the PMC.
11. The ISG issues a request to the TFTP server and asks for the file isg_trunk.sdp.
12. The isg_trunk.sdp is sent to the ISG, which reads the information and stores in its memory.
If the TFTP server fails, the (existing) data is used.
13. From this moment on the ISG will apply the settings found in the isg_trunk.sdp.
14. The ISG is ready to make/receive calls.
