According to my "Sun 3/50 Desktop Workstation Hardware Installation Manual"
part #800-1355-05 Revision A of 31 January 1986 pg. 18:

	Attach the keyboard, mouse, ...

	CAUTION: Make sure that you have not connected the workstation to a 
		 power source at this point; connecting or disconnecting the 
		 keyboard with power on may damage keyboard circuitry.

Perhaps Jordan was implying that you should halt, and power down your Sun 
before detaching the keyboard and locking it in your desk.
Sorry for the digression X-folk, I'm redirecting followups to comp.sys.sun.
