Once all services are running and the IMG 1004 software build is available and installed on GCEMS server, power on the unit by toggling the power switch on the rear Power Module to 1(ON).
The IMG 1004 will now get the software load from the GCEMS server. The IMG 1004 utilizes the LED's on the front panel to display different aspects of the boot sequence. As the IMG 1004 goes through its boot process the LED's will indicate what part of the boot process the IMG 1004 is checking and if any problems occurred. When the LED's go through the Download Complete state shown in the table below, then software has completed its download. Once the download is complete the LED's will change to the status of each respective aspect and is ready for configuration. See the Front Panel Status LED's link for more information on LED status during the booting process

If the software load does not transfer to the IMG 1004, check the following:
Verify that the Linux firewall is disabled.
Verify that DHCP and VSFTP services are running.
Verify that the etc/dhcpd.conf file is correct
Verify that the switch bin file is in the correct location (/home/excelsw/ftpBuilds).
Verify that the link to the switch bin created in /home/excelsw/ftpBuilds is correct.
Example: img1004_id0106.bin -> img1004_ver1050xxx_id0106.bin
Note: Script lnimg (link img) can be used to create this link.
Note: If the system software image gets corrupted during the download process, the IMG 1004 will not load the corrupt image. Instead, the IMG 1004 will flash the code below and then execute a reset of the IMG 1004.
The following illustration shows the transfer of IMG 1004 System Software using FTP from an FTP server to each IMG with a local BootP Server.
