Initialization Process Overview
The initialization process of the device is responsible for network connectivity and operation of the device in your
local network. Once you connect your device to the network and to an electrical supply, the device begins its ini-
tialization process.

Loading the ROM File

Configuring the VLAN

Querying the DHCP (Dynamic Host Configuration Protocol) Server

Contacting the Provisioning Server

Updating Firmware

Downloading the Resource Files
Loading the ROM File
The ROM file resides in the flash memory of the device. The device comes from the factory with a ROM file pre-
loaded. During initialization, the device runs a bootstrap loader that loads and executes the ROM file.
Configuring the VLAN
If you connect the device to a switch, the switch notifies the device of the VLAN information defined on the switch (if
using LLDP or CDP). The device can then proceed with the DHCP request for its network settings (if using DHCP).
Querying the DHCP (Dynamic Host Configuration Protocol) Server
The device is capable of querying a DHCP server.
After establishing network connectivity, the device can obtain the following network parameters from the DHCP
server during initialization:
IP Address
l
Subnet Mask
l
Default Gateway
l
Primary DNS (Domain Name Server)
l
Secondary DNS
l
By default, the devices obtain these parameters from a DHCPv4. You can configure network parameters of the
device manually if any of them are not supplied by the DHCP server.
Contacting the Provisioning Server
If you configure the device to obtain configurations from the provisioning server, it will be connected to the pro-
visioning server, and then download the boot file and configuration file(s) during startup. The device will be able to
resolve and update configurations written in the configuration file(s). If the device does not obtain configurations
from the provisioning server, it will use the configurations stored in the flash memory.
Updating Firmware
If you define the access URL of firmware in the configuration file, the device will download the firmware from the pro-
visioning server. If the MD5 value of the downloaded firmware file differs from that stored in the flash memory, the
