FREQUENTLY ASKED QUESTIONS

Questions and Answers

Q. What servers can the monitor be used with?

A. All Sun and headless servers to date include at least one serial RS232 port that is used as a console port when no directly connected keyboard is present. The Ethernet console connection should only be used with servers that include an Ethernet RSC (Remote System Control) port. Both RS232 serial and Ethernet telnet connections cannot be active at the same time.

Q. How do I connect the terminal to a single server using a RS232 serial connection?

A. An RS232 cable is required for connection to a server with either a male DB25 or DB9 serial port. When connecting to a Sun server with a RJ45 console port, use the RJ45 cable and RJ45 to DB25 adapter which are included with the server. If the RJ45 to DB25M adapter and RJ45 cable are not available, contact NTI to order DB25M-RJ45F-T (adapter) and a Cat5 Patch cable (RJ45) of the desired length.

Q. How do I connect the terminal to multiple servers using a RS232 serial connection?

A. A Console Server must be used to connect the terminal to multiple servers. Ensure that the appropriate cables are ordered for connection to the Sun servers in addition to a terminal cable terminating in a female DB9 (or male DB25 when used in conjunction with the included adapter) connection. To connect to a server, the operator will first connect to the Console Server, and then use Console Server functionality to connect to the server.

Q. What is the format of the server serial connection on the terminal? A. The pin out adheres to a standard female 9 pin [PC] connector.

Q. How do I connect the terminal to a single server using an Ethernet telnet connection?

A. When connecting to a Sun server with an Ethernet RSC console port, a crossover or cascade Ethernet cable may be used. Alternatively, an Ethernet switch and standard RJ45 cat 5 Ethernet cables may be used. When using an Ethernet switch, it is advisable that this network remains private for security reasons.

Q. How do I connect the terminal to multiple servers using an Ethernet telnet connection?

A. An Ethernet switch must be used to connect the terminal to multiple servers. Standard RJ45 Cat 5 Ethernet cables should be used to connect the switch to the terminal and servers. In use, the operator can switch the terminal connection between [up to] 12 servers by using the hot key sequence ALT-F1 through to ALT-F12. The state of each server session is preserved by the terminal. It is advisable that the network used to connect the server consoles remains private for security reasons.

Q. How many servers are supported by the Ethernet telnet connection?

A. The terminal allows up to 12 Ethernet connected servers to be configured.

Q. Does the terminal require an IP address when using an Ethernet connection?

A. Yes. This is defined during terminal set up.

Q. Is any server configuration required?

A. When the terminal looses power or is powered OFF, a 'break' may be generated on the RS232 host communications port (as is common with most general purpose terminals). To prevent this halting a Sun server, ensure that the "alternate break" sequence is configured. See SunSolve Info Doc 21258 for details. If connecting the terminal using the RS232 connection to a Console Server, an alternate break sequence may not be required since some Console Servers are "Break Safe" (as is the case with all Sun UK marketed Console Servers). Refer to the Console Server documentation for details. When using an Ethernet console connection, the alternate break sequence need not be defined. However, the RSC Ethernet port must be configured using the "rscconfig" command.

Q. Does the keyboard support any Sun specific keys?

A. No. Character terminals are non Sun specific, and do not require any special keys. The Break key can be used to enter the Open Boot PROM "OK" prompt.

Q. What character resolutions does the terminal support?

A. The standard resolution is 80x24 plus a status line displayed using 800x600 pixels.

Q. What rack can I mount the unit in?

A. The rack mounted monitor has been qualified in the Sun StorEdge 72" and Sun Fire racks. Although it is not possible to guarantee, the rack mounted monitor should be compatible with other EIA 19" racks.

Q. What is the warranty?

A. The warranty period on this product (parts and labor) is two (2) years from the date of purchase.
