    CPS Hardware Review this section to familiarize yourself with the CPS. It describes the front and rear panels, connector pinouts and device cabling. About the CPS The INIT button (Figure 1) can be used to remove configured information from a CPS unit. The CPS stores nonvolatile data, such as IP addresses and usernames, in a database in FLASH.
  • Page 14 Figure 2: CPS Rear Panel CPS1610 shown On the rear of the CPS, there are 8 (CPS810) or 16 (CPS1610) RJ-45 connectors for serial cabling, a LAN connector for a 10baseT or a 100BaseT Interface cable and a power receptacle.

  • Page 17 BOOTP servers require the Ethernet MAC address of network devices. The Ethernet MAC address of the CPS is located on the rear panel of the CPS above the LAN connector. Once you have configured your network’s BOOTP server with the Ethernet MAC address, IP address and subnet mask for the CPS, restore power to the CPS and wait for the ONLINE LED to illuminate.
  • Page 18 CPS 810/1610 Installer/User Guide Once the IP address has been successfully configured, launch a TELNET client to the IP address of the CPS to perform the initial CPS login. For additional information, see Initial Login to the CPS in Chapter 2. TELNET Command Line Interface The CPS can also be configured directly from a TELNET Command Line Interface (CLI).

DS Application Software Avocent’s DS software is a Windows-based application that offers an industry standard interface to locate and manage Avocent’s digital KVM switches, CPS units and attached devices. The TELNET client built into DSView and DSAd- min is similar in functionality to the vConsole version, but only supports secure sessions with the CPS.

On certain servers, the serial break sequence has a special meaning. The BREAK access right allows the CPS administrator to grant this capability only to those users that need access to the PORT BREAK command.
  • Page 31 These commands are used to control your session with the CPS CLI or with the attached serial device. BREAK On certain attached serial devices, sending a serial break can have serious effects, such as rebooting or interrupting the operating system. The Break sequence enables a serial break via the PORT BREAK command.

  • Page 39: Cps Command Line Reference

    CPS Command Line Reference This section contains a complete description of each CPS command. Most commands require access rights in order for you to use the command. Each command is presented with its syntax and the access rights that are needed to use the command.
  • Page 40 CPS 810/1610 Installer/User Guide If the requested port number is in use, then the CPS will generate the error: ERR 504 - Specified port is already in use The CLI access character can be typed to gain access to the Serial CLI again. However, this does not disconnect the user from the port.

  • Page 41: Disconnect Command

    You enter CLI mode and use the QUIT command to terminate the Serial CLI session You do not transmit any data to the serial device and the connected port times out. When this happens, the CPS notifies you that you are no longer connected to the serial device and your Serial CLI session returns to CLI mode.
  • Page 42 CPS 810/1610 Installer/User Guide setting of that parameter remains in effect. Multiple keyword parameters may be specified on a single command. This command allows the serial port settings (BAUD, SIZE, STOP, PARITY, FLOW and TIMEOUT) for a specific port to be set. These are the settings that will be used for the serial port.
  • Page 43 If you use hardware flow control, be sure that these control signals are cor- rectly wired or there may be loss of data. TIMEOUT Specify the number of seconds for session timeout. The CPS monitors data traffic between your session and the attached serial device. If no data is received or transmitted to your TELNET session, then your session will time out after the number of seconds specified in this parameter.
  • Page 44 CPS 810/1610 Installer/User Guide You may then use one of the following commands : PORT HISTORY Rights Required: None A 64K history buffer is maintained for each CPS port. Each buffer is a circular queue that contains the last 64K of data that has been received from the attached serial device.
  • Page 45 RESUME The RESUME command leaves the PORT HISTORY CLI mode and CLI mode, resuming the serial session with the attached serial device. This command provides an easy means to leave PORT HISTORY mode without have to QUIT and then RESUME in the CLI mode. SEARCH The SEARCH command searches the port history buffer for a specified text string.

  • Page 46: Quit Command

    CPS 810/1610 Installer/User Guide By default, the SEARCH command is case sensitive. Entering -i after the search command will perform a search that ignores case. For example: PORT HISTORY> s Process (search for ‘Process’) PORT HISTORY> s -i Process (search for ‘Process’ ignoring case) The TOP command sets the current history display line to 1 and outputs a history display page.

  • Page 47: Resume Command

    RESUME Command RESUME (no parameters) Rights Required: none To resume your connection to the attached serial device, enter the RESUME command. You will then exit the CLI and reconnect to the attached serial device. If any data was received while you were in command mode, it is contained in the history buffer.
