Page 7: Chapter 1 Overview
Chapter 1 Overview This manual describes the software installation and network management procedures for the AT-3600 series of independently manageable hub/repeater models. The AT-3600 series also includes “Slave” modules that are not manageable as standalone devices (the AT-3624TS and AT-3624TRS models) and a bridge module, the AT-3675. -
Page 8: Features
Overview Each manageable AT-3600 Series Repeater is a single building block for both standalone (repeater) and chassis (department concentrator) configurations. Allied Telesyn International (ATI) supplies desktop and rackmount department concentrator chassis that can hold up to eight AT-3600 Series Repeaters. Since the department concentrator chassis connects repeater modules across a backplane, a fully populated department concentrator behaves as a single repeater in the network topology. -

Page 10: Chassis Configuration
Overview Chassis Configuration You can use a single manageable AT-3600 Series Repeater in standalone mode or as part of a department concentrator housed in a chassis. Various chassis models are available for desktop or rackmount configurations. These include 1-, 2-, 3-, 4-, 7-, and 8-module combinations for desktop or 19-inch rackmount installations with standard or fragmented backplanes. -
Page 11: Network Management
CentreCOM 3600 Series Hub/Repeaters Network Management All manageable CentreCOM AT-3600 Series Repeaters are equipped with network management agents. In a standalone configuration, the agent makes the repeater a manageable node (or hub ) on the network. In a department concentrator, the Master module provides agent services for the entire concentrator. - Page 12 Overview These three commands are executed against a lengthy list of variables (or managed objects) contained in either MIB II or the Repeater MIB. For example, TCP/IP and SNMP network parameters include: Repeater IP address, Subnet mask, Gateway address, SNMP manager address, ‘Trap’ community string, ‘Location’...

Page 21: Chapter 2 Installation
Chapter 2 Installation CentreCOM Multiport Hub AT-3600 Series Repeaters act as IEEE 802.3 compliant Ethernet compatible installations. They support multiple stations on the network and have an additional network port for an AUI or other media appliqué to enable connection to the network’s main Ethernet backbone. An RS232 port allows connection to an asynchronous terminal or PC with terminal emulation for hub management. -
Page 22: Software Installation
Installation The management agent actually resides in every AT-3600 module, except the AT-3612FS, AT-3624TS/AT-3624TRS. These three models are configured as Slaves and can never serve as Master or Backup modules. The agent in the Master is active and available for use. The agent in the Backup remains inactive unless the Master fails. -
Page 23: Figure 4: Firmware Cassette Location
CentreCOM 3600 Series Hub/Repeaters To reinstall or update the management agent 1. If you are loading software in a single standalone repeater, turn off the power for the repeater and skip to step 3. 2. If you are loading the software to a hub consisting of multiple modules in a department concentrator chassis, remove the Master from the chassis. -
Page 24: Updating Other Repeaters
Installation For a standalone repeater, the software installation is complete. 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. -
Page 25: The Rs232 Management Port
CentreCOM 3600 Series Hub/Repeaters The RS232 Management Port AT-3600 Series Repeaters have a special management port for connecting a user-supplied serial device. 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 (see Figure 5) commonly used on PCs. - Page 26 Installation AT-3600 Repeaters support various commonly used data rates ( baud rates ), from 75 bps to 19.2 kbps, as well as an automatic baud rate detection mode. Automatic baud rate detection mode is the default setting and facilitates repeater connections. The interface supports either 7 or 8 data bits; even, odd or no parity;...

Page 27: Repeater (Hub) Management
Chapter 3 Repeater (Hub) Management User Interface The AT-3600 management user interface enables you to control AT-3600 activities and the Statistics Database. You can access the management agent either by direct connection, via the RS232 port, or remotely, via a network virtual circuit connection. -
Page 28: Table 4: Optional Terminal Control Sequences
Repeater (Hub) Management The management agent can also take advantage of selected special control (escape) sequences that the terminal may use for screen control. Table 4 lists these special sequences: Table 4: Optional Terminal Control Sequences Home Cursor Moves the cursor to the top-left screen position. Erase Screen Erases the entire screen, or erases from the current position to end-of-screen. -
Page 29: Statistics Database
CentreCOM 3600 Series Hub/Repeaters Statistics Database Omega maintains a database of statistical data on physical and datalink layer activities. It is actually a distributed database—portions of the database reside within each module of a hub. The Statistics Database complies with standards for Hub MIBs from the IEEE and the TCP community. -

Page 61: Chapter 5 Fault Tolerance
Chapter 5 Fault Tolerance As previously mentioned, you can cluster multiple AT-3600 Series Repeaters in the same chassis, where they will all operate together as a single logical concentrator. You manage the entire department concentrator (via the management agent) from the Master AT-3600 module. Modules are numbered from 1 through 8, top to bottom, in the chassis. -
Page 62: Module Failures
Fault Tolerance If you remove the Master, role determination will cause the Backup to take over as the new Master. The module below the old Backup (now the new Master) will take on the role of a new Backup. This process will repeat again if the new Master is itself removed. -
Page 63: Precedence
CentreCOM 3600 Series Hub/Repeaters When a Backup takes over on behalf of a failed or removed Master, it already has a current copy of all necessary configuration data. When you swap out the failed Master and install a new module, the new Master will receive correct and current configuration data from the Backup (previous Master). - Page 64 Fault Tolerance Limitations also exist when massive chassis reconfigurations occur. If all modules boot at the same time, the voting process described above is performed. If many modules have been swapped all at once, incorrect data could be used. If, for example, several modules had previously been installed together in a different chassis, they would all “vote”...
