MATRIX SERVSWITCH™
3.5 The Power-Up Procedure
About three seconds after you plug in and turn on a Matrix ServSwitch as
described in Section 3.3.7, a diagnostics screen running a self-test will appear on
user-station monitors and serial devices attached to the Switch. (In an all Sun
installation with a monitor that doesn’t support 640 x 480 resolution, the video
port of a powered and operating Sun CPU needs to be connected to the Matrix
ServSwitch’s lowest-numbered CPU port in order for the Switch to display this
screen properly—see Section 3.3.5.) This screen and its standard messages are
discussed in Section 3.5.1. Error messages that might appear instead are discussed
in Section 3.5.2, and the special set of information that appears on serial
connections is discussed in Section 3.5.3. After a few more seconds, the screen
disappears and either a login box or a connection-status box appears.
If your system is a Matrix ServSwitch daisychain, power up each Switch
separately, waiting approximately 15 seconds for diagnostics to complete. You will
also want to initially configure each Switch separately as described in Section 3.6.
If any mouse that’s not attached to the Switch at power-up is plugged in later, the
Switch will not be able to autodetect its type and will, by default, try to interact with
it using the PS/2 mouse protocol. Likewise, the Switch will default to PC mode 2 if
you attach a keyboard after power-up. This protocol will not work with Sun
keyboards and there’s no way to change the default setting, so if you need to attach
a Sun keyboard after power-up, you’ll have to turn off the Matrix ServSwitch, plug
in the keyboard, and turn the Switch back ON.
Once you’ve plugged in and turned ON all of the Switches in your system, and
have also initially configured them, power up the remaining CPUs connected to
the system one by one, giving each one time to boot completely before turning ON
the next one. When the CPUs are powered up after the Matrix ServSwitch, the
Switch emulates all keyboard and mouse functions for automatic boot-up. (You
might want to issue a Keep Settings command after initial bootup, so that the
Switch saves the mode settings it has autodetected to nonvolatile memory.)
