CHAPTER 4: Operation: Hardware and Keyboard Commands
4.3.9 I DENTIFY ROM
Unfortunately, as with all complex equipment, problems might arise with your
ServSwitch Ultra that require the assistance of technical-support personnel. One of
the things technicians might want to know when they attempt to diagnose and
correct your problem is the revision level of your Switch’s ROM. This command
causes the ServSwitch Ultra to send the four-character “UPxx” ROM level to the
currently selected CPU as ASCII keyboard data; these characters will be echoed
back to the shared monitor if you are at some type of prompt. (You must be at
some kind of prompt or screen capable of displaying typed-in keyboard characters,
or you will not see the Switch’s response.) To issue the Identify ROM command,
press and release the left Control key, then type [I].
4.3.10 S END [S TOP ]
The Sun keyboard has too many keys for them all to be mapped one-to-one to keys
on a PC or Mac keyboard, so there are a few Sun keys that PC and Mac keyboards
can’t directly reproduce. (See Section 4.1.2 and Table 4-1 on page 37.) If you
absolutely have to use a PC or Mac shared keyboard, you can use this command to
cause the ServSwitch Ultra to send the currently selected CPU the scan code for
the Sun [Stop] key. (This key, on the left-hand end of the Sun keyboard, is the
only one of the non-mapped keys that is widely used at the time of this writing; it
can be used, for example, in the [Stop][A] key sequence to cause some Sun CPUs
to go to a boot prompt.)
To issue the Send [Stop] command, press and release the left Control key, then
press the [Pause] key (often labeled [Pause (Break)] on PC keyboards or
[F15 (Pause)] on Mac keyboards). This command is valid even if issued from a Sun
keyboard. Do not send [Stop] to a PC or Mac compatible CPU; this could have
unpredictable results.
4.3.11 D ISPLAY L ABEL
One of the ServSwitch Ultra’s graphic-overlay functions is to display the on-screen
“label” window that contains the number and assigned name of the currently selected
CPU (see Section 5.4.3). If this label is not on screen, you can use this command to
cause the Switch to display the label for the length of time you have configured for
the label’s “fadeout interval” (see Section 5.4.3.D), or, if fadeout is disabled, for
five seconds. (If fadeout is set to 255, the label will be displayed at all times.)
Conversely, if the label is being displayed and you want it to go away, issuing the
Display Label command while the label is on screen will cause it to disappear.
To issue the Display Label command, press and release the left Control key, then
type [D].
