Attention
Upon initial power-up, the LEDs (including the red Fault lights) on all
units connected through a chassis backplane will activate. This is a normal
cycling function and is not any indication of a problem.
AT-3600 Port Configurations
RS232 Terminal Port
All AT-3600 Series manageable hubs include an RS232 Terminal Port on
the front panel. Figure 7 shows the RS232 Terminal Port whose principal
use is the connection of a local network management terminal to access
Omega.
This port conforms to the signaling characteristics of EIA standard RS232
and implements the signals necessary to support an asynchronous device.
The physical connector is not, however, an RS232 DB25, but is instead a
DB9 commonly used on PCs.
Note
For more information, including pin-out assignments for enabling an
AT-3600 module as Data Communication Equipment (DCE) or as Data
Terminal Equipment (DTE), refer to the
CentreCOM 3600 Series and AT-S4
Firmware Module Network Operations Manual.
Appliqué Ports
AT-3600 Series hub models feature a variety of port counts and support a
variety of media, including:
❑
Fiber optic(10BASE-FL), using ST, SC, or SMA connectors
❑
Thinnet (10BASE2), using BNC connectors
❑
UTP/STP (10BASE-T), using Telco RJ21 or RJ45 connectors
❑
Thick Ethernet (10BASE5), using the AUI connector
AT-3600 Series hubs with management capability have a convertible
network (appliqué port located on the front panel. In a department
concentrator configuration, you might typically use one hub module’s
appliqué port for the network connection and the other modules’ appliqué
ports for station connections.
The network appliqué port is convertible on all AT-3600 Series hubs with
management capability. You may configure it by replacing the network-
interface appliqué (or (internal transceiver) as described below, or you
might have purchased it preconfigured at the factory.
