Powering on or Powering off VP59
VP59 powers on automatically after you connect an electrical supply, and it powers off when you
disconnect an electrical supply.
Initialization Process Overview
Once connected to the network and an electrical supply, the system begins initializing.
• Loading the ROM File
• Configuring the VLAN
• Querying the DHCP Server
Loading the ROM File
The ROM file, came with the system, is stored in the system flash memory. During initialization, the system
runs a bootstrap loader that loads and executes the ROM file.
Configuring the VLAN
If you connect the system to a switch, the switch notifies the system of the VLAN information defined on the
switch. The system can then proceed with the DHCP request for its network settings (if using DHCP).
Querying the DHCP Server
The system is capable of querying a DHCP (Dynamic Host Configuration Protocol) server. After
establishing network connectivity, the system can obtain the following network parameters from the DHCP
server during initialization:
• IP Address
• Subnet mask
• Default Gateway
• Primary DNS (Domain Name Server)
• Secondary DNS
By default, the system obtains these parameters from a DHCPv4. If the DHCP server does not supply
some of the above parameters, you can configure them manually.
Running the Setup Wizard
The setup wizard appears on the monitor when you initialize the system for the first time or when you reset
the system to factory. You can select the desired language via your remote control or CTP20/CTP18, and
configure the following features according to the setup wizard.
