INTRODUCTION

  This is a production release of firmware for the PortServer TS 8/16 and
  TS16 rack.

SUPPORTED PRODUCTS

  The code supports the following devices:

      PortServer TS 8
      PortServer TS 16
      PortServer TS 16 Rack

ENHANCEMENTS     

The "D" release adds support for TCP Tunneling, and speeds up the
re-establishment of auto connections, after a session has been closed or
disconnected.  DHCP will now handle an 'infinite lease' assignment and the
DHCP server selection has been enhanced.


ADDITIONAL INFORMATION

ADDP (Advanced Device Discovery Protocol) - Allows the system to identify
all the Digi devices attached to a network by sending out a multicast
packet.  If a Digi device has ADDP it will respond to the multicast packet
and identify itself to the application sending the multicast.  If your Digi
device is not found, enable multicast forwarding on your router.

ADDP also allows users to assign an IP address to devices with an IP
address of 0.0.0.0.  The capability to assign an IP address has been implemented
in the Digi software utility, DPA - Remote (Digi Port Authority - Remote)
version 2.01 and later.  

To assign an IP address from DPA - Remote: Run ADDP
discovery, select a device with an IP address of 0.0.0.0, then press
Configure.

Upgrading the POST code and EOS 
--------------------------

Upgrade the POST code before upgrading from a firmware release prior to
82000684_B.  The release history below identifies the versions of
firmware that are compatible with specific versions of POST code.  If you are
unsure which version of POST code  you are running, upgrade to the most
recent version.  The most recent POST code, 82000685_C, is located at
ftp://ftp.digi.com/support/firmware/psts8-16/.  Use the following OS command to
load the POST code first:

  boot load-boot=<tftpserver>:82000685_C.bin

Reset to allow the new POST code to run.

  boot action=reset

Upgrade the EOS with the command:

  boot load=<tftpserver>:82000684_D.bin

Reset the unit after the EOS  upgrade as well.
