Troubleshooting EM1
Table of contents generated with markdown-toc
Check to see if a hard drive is installed. If not then a new hard drive must be installed using the em format command (em format /dev/sdb/ disk number). You can check to see if a drive is present by using the command sudo fdisk -l. The data disk is 500GB and, without problems, will be called /dev/sdb1. If a drive is present turn off the box, fully remove the HDD and replace it then turn the box back on. Once the box has rebooted check the main user screen to ensure data is written to the removable drive.
Make sure, using sudo mount after reboot, that /dev/sdb1 is mounted on /mnt/data, and try to mount it there if not. If it mounts, and this problem is fixable manually but the box won't do it on reboot, you could try re-imaging the box as this is a configuration issue.
If removing and replacing the drive does not work then swap the HDD. If this does not work check the internal connections between the HDD caddy and motherboard.
Ensure there is power to the Ethernet switch and lights can be seen next to all cables in/out of the switch. If all lights are present and correct use the keyboard command Ctrl-Alt-Del to refresh the user screen. If lights are missing check the cable and connections into the cameras to ensure the cable isn’t broken or pinched and the camera is connected securely, a cable tester could be used if available. If all connections and cable are fine then try the command ping then the cameras IP address (eg ping 1.1.1.1) which will list what data is being received from the camera. If no data is being received try connecting a different camera to check if it is an internal camera error.
