Lindy CPU IP Access Switch Plus manual Performing a flash upgrade

Performing a flash upgrade

CPU IP is fully reconfigurable via flash upgrade.
To perform a flash upgrade
1 Using a remote connection, log on as the admin user and access the Unit
	configuration page to determine the current firmware version of the CPU
	IP unit.
2	Please contact LINDY Support to get the latest firmware revision.		Configure network option
3	Power down the CPU IP unit. At the rear of the unit, adjacent to the power
	input socket, click mini switch 1 to its ON (down) position.
4	Re-apply power to the CPU IP. On the locally connected monitor you should			Network Config
	see a Maintenance menu:
			MAC	Address	00:0F:58:00:00:04
	Maintenance		Use	DHCP	No
			IP	Address	192.168.42.154
	To upgrade unit, visit:		Net	Mask	255.255.255.0
			Gateway
	http://192.168.42.154
	Configure Network	Current network			OK
		address of the
	Reset Configuration
		CPU IP
	Put option switch 1 up to
	return to normal operation.

The Maintenance menu should display the current network address of the CPU IP.

•If the current network address is incorrect then select the ‘Configure network’ option to change it:

5Use the web browser (not the VNC viewer) on the previously used remote system, connect to the network address shown in the local Maintenance menu.

6Follow the on screen instructions to upload the firmware file (previously obtained from LINDY) to the CPU IP.

IMPORTANT: Wait until the upgrade is complete.

7When the upload is complete and confirmed on screen, log off the remote system and then power down the CPU IP.

8At the rear of the unit, return the mini switch 1 to its OFF position and then re-apply power.

MAC address

Media Access Control address – this is the unique and unchangeable code that was hard coded within your CPU IP unit when it was built. It consists of six 2-digit hexadecimal (base 16) numbers separated by colons. A section of the MAC address identifies the manufacturer, while the remainder is effectively the unique electronic serial number of your particular unit.

Use DHCP

When this option is selected, your CPU IP will attempt to locate a DHCP server on the network. If such a server is located, it will supply three things to the CPU IP: an IP address, an IP network mask (also known as a Subnet mask) and a Gateway address.

IP address

This is the identity of the CPU IP within a network. It can either be entered manually or configured automatically using the DHCP option. When the DHCP option is enabled, this entry is greyed out.

Net mask

Also often called the ‘subnet-mask’, this value is used alongside the IP address to help define a smaller collection (or subnet) of devices on a network. In this way a distinction is made between locally connected devices and ones that are reachable elsewhere, such as on the wider Internet.

Gateway

This is the address of the device that links the local network (to which the CPU IP is connected) to another network such as the Internet. Usually this is a network switch or router and it will be used whenever a device to be contacted lies outside the local network.
