|On-Line Demonstration of the DCB Access Switch Managing Network Equipment
||This is an actual on-line connection to real DCB equipment. By using our EtherPath ethernet to RS-232 server connected to an Access Switch, you can telnet to the Access Switch, select management ports on various DCB products, control power switches, and even configure the equipment... right now through the Internet!
Learn how easy it is to control and troubleshoot multiplexer systems, reboot hung servers, and assist your users using our multiplexer commands. The connection is not a simulation... since this is real equipment, you can move through the menus, configure ports, even reset and restart the equipment. At present, we have the following connected to the Access Switch...
Your browser must have a telnet application defined for these buttons to work.
|Now what do I do?||Once you make a connection, the EtherPath responds with "Connect OK! ". The Access Switch may need to autobaud, so hit one return. (It may respond with "WHAT?") You then get an "Access >>" prompt and are at the command interface for the Access Switch. It's that easy, you are now connected to the Access Switch and can enter any valid Access Switch command. A good "first" command would be the "Help command". Type H and press enter. The Access Switch responds with it's top level of help such as...
Now that you've seen the basic help screen, let's enter the SI command to show port information, or to show what is connected to the ports. The command is SI followed by the return key. The Access Switch displays a port map...
Connect to one of those devices by typing its port name or port number. To get to the multiplexer named SR-4-Dallas, you type one of the following...
|Equipment Connected to this Access Switch||The EtherPath
The EtherPath is the device you TELNETed to. It connects to a 10BaseT ethernet LAN and provides a single RS-232 connection that operates in one of two modes. The first, "server mode", is the way we are using it here. You can telnet to it to access its serial port. We use this with our Access Switches to provide an ethernet connection for managing non-ethernet devices, or managing ethernet devices out-of-band. The second mode, "client-server mode", is often described as an "RS-232 pipe". The Etherpath manual is on-line in PDF format (Click here to retrieve it (a PDF file).
Remote Power Control using the APS-01
Power control ports are slightly different. They use the APS-01 Access Power Switch. You enter the port number or name followed by a space and the power command ("ON", "OFF", "CYCLE"). It performs the function and responds with the current status. If the command was "CYCLE", the cycle is started, and a second message is displayed when the cycle is completed. This demonstration unit has the router (on port 5) plugged into the APS-01. You can tell it to cycle power, then quicky go to the router to watch it boot up. The APS-01 manual is on-line in PDF format (Click here to retrieve it).
The SPL Multiplexer
The SPL multiplexer is connected to port 2 of the Access Switch. This multiplexer is available in models with two to fourteen ports. This multiplexer is also used at the "drop" end of DDS multi-drop applications. The SPL manual is on-line in PDF format (Click here to retrieve it, a 1.7 Mb file).
The SR Multiplexer
The SR multiplexer, connected to port 3 of the Access Switch is available in models from 4 to 32 ports. The SR is used at both the host site and remote site for point-to-point DDS or frame relay systems. It is also used with multi-point frame relay systems at the drop sites. (The SRX model is used at the host end of multi-point frame relay system). The SR manual is on-line in PDF format (Click here to retrieve it, a 161 Kb file).
The SRX Multiplexer
The SRX multiplexer, connected to port 1 of the Access Switch is available in models from 8 to 32 ports. You can also "gang" multiple SRX units at the host site up to 64 ports. The SRX is used at the host site with multi-point frame relay systems. (The SR model is used at the drop end). The SRX manual is on-line in PDF format (Click here to retrieve it, a 2 Mb file).
The WAN Router
This is a Compatible Systems 900i MicroRouter. The console port is connected to the access switch. It has a password (letmein) that must be entered when accessing it.
This is a spare AsanteHub 1012 managed hub we happened to have around the shop. It isn't connected to the ethernet.
