## Removing Disk Pack

Removing the disk pack is simple and straight forward, use the following steps

### Step 1) remove the dust filter

The system has a dust cover filter on the front of the system. This filters out unwanted particles from entering the eletronics components. As the system is designed to operate in non-datacenter environments.

Remove the screws as shown below

## Default AC Power setting

By default the 5403 systems are shipped to power on once the mains AC power is connected. This is typically the server use case, e.g. if there is a power outage capture devices should power on automatically when the power is restored.

For portable systems it may not be the best setting. To configure the setting requires BIOS per the below

### Step 1) Enter the BIOS

Type the DEL key on the KVM when the system is booting. This shows the menu below
