INTRODUCTION

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

SUPPORTED PRODUCTS

      PortServer TS 8
      PortServer TS 16
      PortServer TS 16 Rack

ENHANCEMENTS     

The "C" release adds support for PPP, Port Buffering, SSH(SSH2 only), Ping/ARP, 
Force DCD option (auto connect 3-wire), User Data, and ADDP - see ADDITIONAL INFORMATION.

BUG FIXES        

      - Complies with SNMP CERT test suite.

KNOWN LIMITATIONS   
  
      - RADIUS for PPP dial-up connections is only supported if the IP-pool is part of
	the local network. 
 
      - RADIUS based authentication is not supported in conjunction with SSH.

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, multicast forwarding may need to be enabled on your router. 

ADDP also allows users to assign an IP address to devices with a 0.0.0.0 IP address.  
The assign IP address capability has been implemented in the Digi software utility, 
DPAR (Digi Port Authority - Remote) version 2.01 and later.  To assign an IP address 
from DPAR: Run ADDP discovery, select a device with an IP address of 0.0.0.0, then press Configure.

A TFTP server will be required for the following steps:

Upgrading the POST and FEP
--------------------------

When upgrading from a firmware release prior to 82000684_B, the POST code must be upgraded first. 
The release history below identies what versions of firmware are compatible with which versions of POST code. 
If you are unsure which versions of POST code you have, we recommend you upgrade to the most recent version. 
The most recent POST code, 82000685_C, is located at ftp://ftp.digi.com/support/firmware/psts8-16/. 
This can be done from the OS with the command:

Load the POST code first with the command:

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

A reset is necessary to allow the new POST to run.

  boot action=reset

Upgrade the FEP with the command:

  boot load=<tftpserver>:82000684C.bin

The unit should be reset after the FEP upgrade as well.
