4 User Interfaces (Using Advanced Control Cards SM533-C and
SM534-C)
4.1 General Description
This documentation describes the following types of control (using Advanced Control Cards
SM533-C (12VAC) and SM534-C (-48VDC)) for the Automatic Switching System:
1.
Control via ASCII commands requires text entry of commands. Communication with the
SM500A chassis is via local connection (COM port) or Ethernet/Telnet session.
2.
Control via SNMP protocol requires use of an SNMP manager, which uses a
Management Information Base (MIB) and a set of commands to exchange information
between the SM500A chassis and manager.
3.
Control via Web browser uses a standard browser interface for performing switch
operations with the SM500A chassis. The browser shows a graphical view of the chassis
and provides point and click operation.
4.
Control via Advanced GUI Based Management uses proprietary software. Similar to the
Web browser interface, the program provides a graphical view of the SM500A chassis
and provides point and click operation.
The following chapters will describe in detail each control configuration.
4.2 System Diagram
Figure 4.1 shows a typical system diagram of the Automatic Switching System SM500A with
the following setups:
1. Remote control
—Each chassis is connected to an Ethernet hub via an Ethernet port
located on the Advanced Control Card. Users may access each chassis from a remote
computer by using SNMP protocol or by issuing ASCII commands via Telnet. Each chassis is
identified via IP address.
2. Local control
—The top chassis is locally connected to a computer or terminal via the
chassis COM1 serial port. Users may access the connected chassis using ASCII commands.
Additionally, a local connection to each chassis is required to set their IP addresses prior to
remote access.
3. System gang switching connection (optional
)—Cable connections at the GANG
IN/GANG ports of the chassis enable system gang switching. The connections allow the
initiating chassis to simultaneously switch itself and all daisy chained chassis below it.
