3. Now you are ready to start the TFTP download process. Use your network management application to enter

the appropriate information and start the TFTP process.

3.3.3 Setting Up UNIX Station as BootP Server Going Across a Router to the Device

To set up a UNIX station as a BootP server going across a router to a device, proceed as follows:

1. Refer to the instructions in the supporting document for your UNIX station to correctly set up your BootP

environment.

2. Perform steps 1 through 3 of Section 3.3.2.

3. Edit the /etc/bootptab file and add an entry for the device that includes the same name as found in the

/etc/hosts file, using the following:

Syntax:

<host name>:ht=<hardware type>:ha<hardware address>:ip=<ip address of device>:hd=<bootp ﬁle

directory>:bf<hex ﬁle name>:sa=<server address>:gw=<gateway, ip address of router interface on

SERVER side>

Example:

emme_20:ht=ether:ha=00001d139786:ip=150.12.30.20:hd=/tftpboot:bf=30103.hex:

sa=150.12.31.35:gw=150.12.31.1

TIP: On multi-channel devices, such as the EMME, use the hardware address of the interface

that the network is coming in on. For example, if the network connection is connected into

channel D, use the MAC address assigned to channel D.

4. Now you are ready to start the BootP process. Use your management application to enter the appropriate

information and start the BootP process. Or set the dip switch on the device to force a BootP download.
