Allied Telesyn offers Omega management software for the AT-4016TR and 
the AT-4016F on a firmware PCMCIA card, the AT-S13.
PCMCIA Port. The PCMCIA card is a read-only interface used for 
restoring or updating software. If a PCMCIA card is installed before a reset 
or power-up sequence, the switch boots from the PCMCIA card. Otherwise, it 
boots from internal Flash RAM. 
To update software through the PCMCIA port:
1. Insert the PCMCIA card into the PCMCIA port. This port is located on 
the front panel of the AT-4016TR and the AT-4016F and identified as such.
2. Reset the unit with either the reset button located on the front panel or 
the reset option in Omega management software.
3. During this process the red Alarm LED will display while the LEDs will 
cycle through the Network Load LED. When the LEDs return to normal 
operation, the update is complete.
4. Remove the PCMCIA card.
5. Reset the unit again. This will allow the system to boot from flash memory.
The new firmware will be copied to the switching system’s onboard 
nonvolatile flash memory.
 NOTE
Your system must be reset before any software modifications will be 
recognized. This can be accomplished by physically disrupting power to the 
switch or by using the software reset.
