While experiencing issues with low performance and hardware device crashing, certain parts of the Kerio Control box might be replaced. This commonly includes RAM upgrade or replacement, HDD change.
Important: this guide does NOT apply for NG100/NG100W boxes as all the parts are tight to the motherboard.
Experience with hardware disassembling (laptops, PCs, network devices, etc)
NG300/NG300W boxes support up to 8 GB of RAM. It has 1 slot preinstalled, with 4 GB Innodisk DDR3L 1333 SODIMM stick already installed.
Warning: To reduce the risk of personal injury, electric shock, or damage to the equipment,
remove the power cord to remove power from the server. The back panel Power On/Standby
button does not completely shut off the system power. Portions of the power supply and some internal
circuitry remain active until AC power is removed.
- Remove the external cover with a standard PH1 x 75mm or PH1 x 100mm screwdriver: 3 screws at the left and right panels, 1 screw at the bottom panel.
- Now you have access to the internal parts of the box.
- To replace/upgrade RAM, remove the HDD caddy. It is beneath the main part (named Apacer). Remove 3 screws at the perimeter (grey metal rack) and 4 screws for the HDD caddy (black caddy).
Note: you will need a smaller size screwdriver to remove HDD screws.
- Pull the gray rack as it is glued to the device. Beneath it, you will see 1 RAM slot.
- Add a new 4 or 8 GB RAM stick.
- (Optionally) Replace the caddy or disk itself. The preinstalled storage is 32 GB SSD (CF card Type II) connected via SATA.
- Assemble the box to the starting point (backward procedure).
- Switch on the device.
- Verify the RAM is upgraded in Dashboard and System Health Webadmin settings.
- RAM upgrade may require BIOS tweaks. You will need to access the box via serial console. However, it's expected the Linux OS will pick up the RAM increase automatically.
- The HDD replacement needs a complete system restore (kerio-control-rescue). For more information, please refer to Restoring Kerio Control NG series.
- The box warranty is NOT affected by disassembling or upgrading the mentioned parts (RAM, HDD). We strongly recommend that you have previous experience with such procedures in the past.
- If the box is set as an RMA, you should remove the replacement RAM module and put back the original.
