Overview

Each telephone on the network must be assigned a unique IP address. The address can be assigned automatically by a DHCP server, or entered manually at the phone.

Telephone operating software can be updated from a TFTP server. The update process can be initiated manually at the phone, or set to occur daily at a preset time. Operating software is automatically updated during power-up or reset.

Procedures for setting up DHCP and TFTP servers, and updating the phone software, are explained below.

This manual is intended for use by network administrators.

DHCP Server Configuration

The DHCP server requires a scope of IP addresses that can be assigned to the phones. The scope must be configured with the router address, vendor-specific info, and the TFTP server address.

Examples for Windows

2000 Server and Windows NT® Server follow.

_____________________

Windows 2000 Server

Run DHCP from the Administrative Tools menu.

Add Server

You can use an existing DHCP server for assigning IP addresses to the telephones, or add a new server.

1. Select Add Server from the Action menu.

2. Enter the IP address of the DHCP server in the This server field.

3. Click OK.

Add Scope

1. Select the DHCP server you will use for assigning IP addresses to the telephone.

2. Select New Scope from the Action menu to run the New Scope Wizard.

7. If you need to exclude some IP addresses from the range, enter them here, otherwise click Next.

8. You can use the defaults, or enter a new lease duration for telephone IP addresses. Lease duration should be set to 7 days or longer.

When the lease expires the phone shows a diagnostic display if idle, while attempting to negotiate a new IP address lease at preset intervals. If the phone is active, the call will be unaffected and the diagnostic display will be shown when the call is cleared.

If the same IP address is offered by the DHCP server, the phone returns to operation without restarting, otherwise the phone will restart after receiving a new IP address.

9. Select Yes on the Configure IP Options screen.

4. Check the box next to 002 Time Offset.

5. Select 002 Time Offset. If your network time server is set to UTC time, enter the hex value for your location's offset from UTC time in seconds. If your network time server is set to local time, enter

Time Zone Offset

Pacific Standard Time 0xffff8f80 Pacific Daylight Time 0xffff9d90 Mountain Standard Time 0x ffff9d90 Mountain Daylight Time 0x ffffaba0

Central Standard Time 0xffffaba0 Central Daylight Time 0xffffb9b0 Eastern Standard Time 0xffffb9b0

Eastern Daylight Time 0xffffc7c0

6. Make sure the box next to 003 Router is checked.

7. The router IP address may have been entered from the New Scope Wizard. If not, select 003 Router, enter the IP address, then click Add.

8. Check the box next to 004 Time Server.

9. Select 004 Time Server, enter the IP address of the SNTP time server for your network, then click Add.

10. Check the box next to 066 Boot Server Host Name.

11. Select 066 Boot Server Host Name, then enter the TFTP boot server’s IP address in the String value field.

12. Click OK.

13. "002 Time Offset", “003 Router”, "004 Time Server", and “066 Boot Server Host Name” should now appear in the Scope Options pane.

To preclude the issuance of a new IP address each time the phone reboots, it is recommended that ICMP ping prior address assignment be disabled at the DHCP server.
