6: Updating Software

Command Line Methods

If BOOTP or RARP is enabled on the SCS, the download process is delayed by
approximately 30 seconds. The SCS first tries TFTP, and then tries MOP loading,
provided that it has enough information to try each download method.

Downloading and rewriting the Flash ROM and rebooting take approximately two minutes
from the time the

Initialize

Reload

command is issued. If the SCS cannot find or access

the download file, you can reboot the SCS with the code still in Flash ROM. The
OK/Activity LED blinks quickly while the SCS is booting (and reloading code) and then
slowly when it returns to normal operation.

Note:

Before entering the Initialize Reload command, check your settings using

the List Server Boot command.

If you are attempting to update the operating code of an SCS not on a local network, you
must specify a boot gateway (router). To specify the boot gateway, use the command:

Set/Define Server Boot Gateway <ip_address>

The SCS directs subsequent IP traffic to the specified IP address.

Note:

This functionality requires boot code V1.3.

TFTP Method

Some TFTP implementations require a specific directory for the firmware file. See your
host's documentation for instructions.

To manually configure the SCS's IP parameters for a TFTP software reload, use the
following process:

1. Log in to the SCS via Telnet or by direct serial connection.

2. Enter the commands shown in the figure below.

Configuring TCP/IP Reload

Local> SET PRIVILEGED
Password> SYSTEM (not echoed)
Local>> DEFINE SERVER LOADHOST nnn.nnn.nnn.nnn
Local>> DEFINE SERVER SOFTWARE "/SCS1600.SYS"
Local>> LIST SERVER BOOT
Local>> INITIALIZE RELOAD

Note:

For instructions on how to log into the SCS to enter these commands, see

Installation.

The path and filename are case-sensitive and must be enclosed in quotation
marks.

When attempting to boot across an IP router, configure the router to proxy-ARP

for the SCS.

MOP

The firmware filename is the only parameter that the SCS needs to reload via MOP.
Make sure the service characteristic is enabled on the host's Ethernet circuit, copy the
firmware file to the

MOM$LOAD

directory, and reload the SCS using the

Initialize

Reload

command. Be sure to use binary mode for any file transfers.
