Back Panel 1-9n Perform memory dumpsConsole functions are useful for maintenance and repair (for instance,after a server crash) and for OEMs developing software for CS/2500series servers.Console port parity is set to none, and the number of data bits is set to 8.Neither setting can be altered.During firmware configuration, you can enable the console port toperform console functions either at all times (leaving nine ports availableto connect to other devices), or only when the server is in monitor mode.Monitor mode is enabled by pressing the hardware interrupt switch(refer to “Hardware Interrupt Switch” on page 1-4). In monitor mode, allports are disabled for use with multiprotocol communications serversoftware.During firmware configuration, you can also set the data rate of theconsole port to a value between 110 and 9600 bits per second (bps). Thisrate is in effect any time the port is in monitor mode. The rate isindependent of the rate set for the port in multiprotocol communicationsserver software.For firmware configuration procedures, refer to Chapter 4,“Configuration.”Transceiver Connector The CS/2500 series provides an Ethernet network interface (labeled802.3 Transceiver) at the upper right corner of the back panel (seeFigure 1-5). This connector is a female DB-15 equipped with a slidelock.For information on pin assignments for the transceiver connector, referto Appendix A, “Pin Assignments.”Printer Port Connector The CS/2500 series includes a printer interface port to connect the serverto parallel printers with Centronics printer interfaces. The printer port(labeled Parallel Printer) is located at the top left center of the backpanel (refer to Figure 1-5). For information on cabling the server to theprinter, refer to Chapter 2, “Installation.”CS2500BookFile : Overview Page 9 Thursday, December 11, 1997 10:44 AM
