Installation

7.
For a standalone repeater, the software installation is complete.
8.
For a department concentrator Master, plug in the Master’s power cord
and return Master to the chassis. The other modules in the chassis will
then be automatically upgraded from the Master with no impact to the
users on those modules.
In a multi-module department concentrator, the Master controls software
distribution to all of the Slaves within the same chassis. Inserting a software
cassette into the Master and powering up each module will copy the cassette
software into the non-volatile memory of each module in the chassis. Later,
even if you’ve removed the cassette, a new Slave inserted into the chassis will
also be loaded with the same software. This ensures that all modules are
running the same version of software and eliminates any possibility of
incompatibility between different software releases.
If new software is loaded into any module other than the Master, the new
software will be overwritten by the Master at power-up.
Updating Other
Repeaters
The Omega software site license permits you to update other AT-3600 Series
Repeaters through the network. You don’t need to insert an AT-S4 cassette in
each repeater in the network or rack.
The Omega user interface provides commands to load software into any other
specified AT-3600 or to update all AT-3600 modules in the network. To update
software, you must insert the new release cassette into one AT-3600 Master:
from that Master module you can load the new software into other selected
AT-3600 Series Repeaters. If you want, you can run the new software on a
limited number of hubs as a kind of “dry run.” When you have become
familiar with the new release, you can load it from one of the Masters to all
other modules in the network.
You can identify an individual repeater to be updated by its Ethernet
address, its Internet Protocol (IP) address, or a user-assigned symbolic name.
We recommend that you assign a hub name during installation and that all
AT-3600 hub names be unique at least within a particular department. If other
AT-3600 hubs in areas outside the network manager’s control have identical
hub names, they may possibly receive downloads accidentally.
AT-3600 Series Repeaters use the TCP/IP-family Trivial File Transfer
Protocol (TFTP) to download other units internally, whether or not your
network is configured with IP parameters. In a non-TCP/IP installation, the
TFTP protocol will be transparent to the other (non-IP) devices on the
network. Using this industry-standard suite of protocols enables the AT-3600
to load software to another unit even if it is geographically separated, within
the following constraints:
❑
The network path between the two units must be a direct datalink
Media Access Control (MAC) layer path. The units must be physically
connected to the same network cable or be joined only by datalink
layer propagation devices such as repeaters or bridges.
❑
The units may be joined by a network layer device (a router) only if
the device is an IP router and only if each AT-3600 has been
configured with an appropriate IP address and subnet mask.
