Software Upgrades
NOTE: The management circuit board uses “flash ROM”, which allows
firmware upgrades to be received over a serial interface.
Software Upgrade at Attached ASCII Terminal
To upgrade the flash ROM:
•
Obtain a copy of updated StackMaster™ software
•
Establish a serial connection to an ASCII terminal or terminal
emulation.
•
Reset the StackMaster™ Management hub
•
Transfer the file.
Obtaining Updated StackMaster™ Software
Updated software can be obtained through the TRANSITION Networks,
Inc., Bulletin Board Service at:
(612) 941-9304
or by contacting TRANSITION Networks, Inc..
Connecting to ASCII Terminal
NOTE: The DB9 serial port on the StackMaster™ is a DTE device. If the
DB9 serial port cable will be attached directly between two DTE devices,
use a null modem cable. If the cable will be attached to a 9600 baud
modem, use a straight through DB9 cable.
1.
Locate the correct DB9 serial port cable with female DB9
connector.
2.
Attach the DB9 serial port female cable connector to the male
DB9 serial port connector on the StackMaster.
3.
Attach the other end of the DB9 serial port cable (directly or
indirectly through a modem) to an ASCII terminal or terminal
emulator.
NOTE: The StackMaster™ is shipped with standard serial port parameter
values:
baud
9600
stop bits
1

8
parity
NONE
Using methods appropriate to the attached terminal, verify that the serial
port parameters of the attached terminal match the StackMaster™ port
parameter values. If necessary, modify the attached terminal port
parameter values.
