Connection and Configuration, cont’d

IPL M PDP-ES card for DHCP (Dynamic Host Configuration protocol) to have an address assigned automatically.

IPL M PDP-ES interface card configuration

When you connect with the IPL M PDP-ES card for the first time, there are three ways to set up the IP address:

1.Use the ARP command method.

2.Use the direct PC method.

3.Use SIS commands through the RS-232 port.

Once the IPL M PDP-ES has an IP address assigned and on an active network, the on-board default Web pages allow you to configure the interface card.

Configuring the IPL M PDP-ES using the ARP command

You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for your IPL M PDP-ES. The ARP command tells your computer to associate the

interface card’s MAC address with the assigned IP address. You must then use ping to access the IPL M PDP-ES unit, at which point the device server’s IP address is reconfigured.

In order for you to use this setup method, both your computer and the IPL M PDP-ES interface card must be connected to the same LAN. Ensure that your PC is on the same subnet mask as the IPL M PDP-ES card.

Use ARP to configure the IP address as follows:

1.Obtain a valid IP address for your IPL M PDP-ES card from your network administrator.

2.Obtain the IPL M PDP-ES card’s MAC address (UID #) from the label on its face panel.

3.If the interface card has never been configured and is still set for factory defaults, go to step 4. If it has been configured previously, perform a mode 4 system reset. For detailed information on reset modes, see Resetting the unit in chapter 2.

CAUTION Your IPL M PDP-ES card must be configured with the factory default IP address — 192.168.254.254 —before you execute the ARP command, as described below.

4.Access the MS-DOS command prompt, then execute the arp –s command as follows:

Enter the desired new IP address and the MAC address (located on the face panel) for the interface card. For example:

arp –s 10.13.170.15 00-05-A6-00-0A-90

Figure 3-3 — Executing the ARP command

5.Execute a ping command by entering your new IP address at the command prompt. For example:

ping 10.13.170.15

After you issue this command, the unit changes to the new address and starts responding to the ping requests, as shown below. The interface card’s IP address should now be updated to the new address. You can now reconnect using either Telnet or the Web to verify that the update was successful.
