In order to set the IP parameters you have to enter following commands in this order:

xx.yy	is the commission Number	e.g. 10.15.34.aa
aa	is the IP address of the Switch	e.g. 10.15.34.140

enable

network protocol none

network parms 10.xx.yy.aa 255.255.255.0 10.xx.yy.190

1.5 Setting IP parameters using the Hirschmann tool HiDiscovery

Establish a connection via Ethernet cable to the switch and start the Hirschmann tool.

Name switch according commission and location, e.g. BakSwtCtlRom001 and set IP configuration as desired.

Pattern 10.XX.YY.AAA

XX.YY regarding to commission number -> e.g. 10.17.21.AAA

AAA IP address of the switch -> e.g. 10.17.21.140

After setting of name and IP address, select WWW and browser will automatically open the graphical web interface.

1.5.1 Configuration via Browser

In order to open the web based interface of the switch you need a browser, like „Microsoft Internet Explorer“ in version 6+.The web based interface uses the plugin „Java“ Runtime Environment Version 1.4.2.x, 1.5.x or 6.x.

1.5.2 Log on

• Start your browser
• Ensure, that you have turned on Javascript and Java in the security settings of your browser.
• To establish the connection enter the ip address of the switch ( „http://10.xx.yy.aa“) into the address field of your browser
• Log on as “admin” with password "private".

2 HP

After replacing a switch it is necessary to restore the old configuration. Every switch has a config backup, located on the external Backup-HDD in the folder 'config-backups'.
By factory default settings, the HP switch has no IP-Address. For restoring a backup over the web interface it is necessary to set an address over the serial interface first.

2.1 Connecting to the switch with HyperTerminal

Connect your Usb-Serial-Connector with the console port of the switch.

Go into device manager and look which port is used for the USB-Serial connector

File:Device manger.png

Start Hyperterminal

• Start -> Programs -> Accessories -> Communicatios -> Hyperterminal

Create a new connection with any name and click OK. Set the connection mode to the COM Port according the device manager and click OK. Make the following settings:

Bits per second	115200
Data bits	8
Parity	None
Stop bits	1
Flow control	Xon / Xoff

Click at OK and press Enter to establish a connection. When connected, press any key to continue.

2.2 Setup IP address

Type config and press enter to get into the config mode. Configure a basic setup with these commands:

• vlan 1
• ip address <Ip-address><blank><Subnet Mask>

(Set IP according the drawings or check the label)

Now the switch got its IP-Address and it is possible to restore the backup file over the web interface.

2.3 Restore config file

Connect your computer with a network cable to one of the first 8 ports. Set your network adapter to a fixed IP-Address in the same range you gave the switch before, f.e. switch IP = 10.11.12.140, your IP = 10.11.12.100

• Open a web browser and type in the IP-Address of the switch
• Go to System - Updates/Downloads

• Click Update and browse for the backup file of this switch (mind the location, not every switch has the same configuration!), Keep the hook 'Reboot'
• Click Save and confirm reboot
• Wait some time until the switch is rebooted

2.4 Change passwords

After restoring the configuration it is necessary to set the passwords again, they are not saved in the configuration file.

• Enter the web interface of the switch again
• Change to Security/Device Passwords

• Choose Manager and click on <Change>
• Set the username to admin and the password according to the Line
• Confirm password
• click Save

Do the same with Operator:

• Choose Operator and click on <Change>
• Set the username to user and the password according to the Line
• Confirm password
• click Save
