Chapter 4 ShoreGear Switches

Maintenance Guide

4 – 3

Upon restart, the switch is automatically upgraded. (You can monitor

the progress of the upgrade on the Quick Look page.)

Performing a Manual Upgrade

To manually upgrade switch firmware, you need to invoke the burnflash command

from the server.

To manually upgrade the switch’s firmware:

Step 1

From the server command line, enter the burnflash command in this

format:

C:\Program Files\Shoreline Communications\ShoreWare

Server>burnflash -s <switch IP Address>

ShoreGear Switch Boot Options

When a ShoreGear voice switch boots, it requires an IP address to connect to the

network and an application program. ShoreGear voice switches are set to use a DHCP

server for an IP address and to retrieve the application from the switch’s flash memory.

If a DHCP request receives no response, the switch tries a BootP request as a backup.

ShoreTel recommends using static IP parameters configured via the serial port, as this is

much more reliable. If DHCP is to be used, ShoreTel strongly recommends using DHCP

reservations for each switch so that the DHCP lease will not be lost.

If a DHCP server is not available, you can set the IP address manually from the switch’s

maintenance port. The ShoreGear-12 and ShoreGear-Teleworker voice switches can be

set to use a static IP configuration via a Telnet session after they have received an IP

address via DHCP or BootP.

The standard method for booting a ShoreGear voice switch is to boot from the switch’s

flash memory. When a ShoreGear voice switch is first powered on, it reads the boot

parameters stored on the boot ROM, which instructs the switch to load software from

flash memory. When the software starts, it loads its configuration, which is also stored

in flash memory.

Booting from FTP is available for instances when you cannot boot the switch from flash

memory. When you boot a switch from FTP, the operating system and software load

from the FTP site identified in the boot parameters. The loaded configuration is a

configuration received from the TMS server.

If the switch fails to load the application from flash and does not have the IP address of

the ShoreWare server, you can set the IP address and boot parameters by connecting to

the maintenance port and using the configuration menu. The configuration menu

allows you to set the IP address of the switch and enter the ShoreWare server (boot

host) IP address.

IP Address from DHCP

The switch sends requests for an IP address to the DHCP server ten times at increasing

intervals. If the switch receives a response from the DHCP server, the boot process

begins. If the switch fails to get an IP address from the DHCP server, it will use the last

assigned IP address, if known. The switch continues to send requests to the DHCP

server for an IP address.

In the case of a switch using an IP address from a previous state, if the DHCP sends a

conflicting IP address, the entire system will be forced to restart. Use long lease times to
