Out-of-band Operations

ATM network administrators can upgrade

6416SW microcode (but not ATM media

modules) using an out-of-band operation with an

RS-232 plug. To do this, you must

attach a workstation with an emulated

VT100

protocol

to the

6416SW

module.

After

locating

the

directory where

the microcode updates are stored,

use

the worksta

as the 6416SW console. Log on using

the administrator

password

and

enter

the

following

commands:

1. MAINTAIN

(to

activate Maintenance

mode)

2. DOWNLOAD

OUT_OF_BAND

(to

specify

boot

or

operational

code

and

to

load it

in

the

flash

EEPROM of the 6416SW module).

Start the file transfer in the

workstation

using the Xmodem protocol. The transfer

takes approximately 6 minutes for

the

boot

code,

22

minutes

for

the

operational

code,

at

9600

bps

(the

time

is

halved

if

the transfer

is

done

at

19200). bps).

If you enter DOWNLOAD OUT_OF_BAND BOOT, you automatically quit

Maintenance

mode

and activate

the

new

BOOT

microcode.
