Maxc OperationsAppendix107MAXC Room Power Down/Up Procedureby Ron WeaverOCTOBER 1980(Revised April 24, 1984)Filed on [Indigo]MaxcOpsPowerDownUp.BravoAbstract: This procedure itemizes the chronological steps necessary to systematically shutdown the power in the Maxc room when a known power outage is scheduled.EMERGENCY shutdown procedure (for fire or smoke) may be found in Appendix A.A version of this procedure will appear in the Maxc Operations manual.XEROXPALO ALTO RESEARCH CENTER3333 Coyote Hill Road / Palo Alto / California 94304 fpi>qF&p W;r!

Prior to ShutdownIn order to give users adequate notice and to protect files on disk, Tenex should ordinarily bestopped in the following manner.Forty-eight hours prior to the scheduled power outage send a message to the NCC Coordinatorand the Arpanet liaison at SCI via their Arpanet mailboxes CONTROL@BBNC and Green@SCI-ICS stating the period the power will be off and that the IMP will be affected. If the scheduledpower outage is to take place in less than 48 hours then the NCC Coordinator may be reacheddirect by phone: (617) 661-0100. The controller may wish you to call him just prior to taking thesystem down so you can set some switches on the IMP panel.As long as possible before the scheduled downtime (preferably 24 hours or more), notify usersby (optionally) putting a notice in the login message, setting the system downtime cell and recordinga telephone message.

System ShutdownGeneral Methodology:(1) Shut down software systems cleanly(2) Safeguard rotary storage by spinning down all disk drives(3) Get all other power off in the simplest manner possible so that restart can be accomplished without an excessive current surge.MaxcThe system will automatically start notifying users of the impending downtimebeginning one hour before it is to occur. When the zero hour arrives, all jobs willbe forcibly logged out except any job logged in on the Maxc controlling terminal,new logins will be prevented, and "Shutdown Complete" will type out on the Maxcconsole. If there are now no jobs logged in, Tenex will shortly hit a BUGCHK(EDDT breakpoint) at SWHLT1, at which point Tenex is properly halted.If there is a job logged in on the Maxc controlling terminal, it will be necesary tohalt Tenex manually. To do this (for which you must be a wheel):@ENABLE!QUIT.Halt Tenex.Wait for the EDDT preakpoint at SWHLT1. A message such as "$8B>>CHKADRBUGCHK/ SWHLT1" should be printed out.Once the Maxc2 system have halted you may proceed by stopping the rest of thesystems in the Maxc room.AlpineBoot Dorado.

Removing System PowerMaxc Disk DrivesTurn off Front switch first, then the switch in the rear.NOTE 2:An alternate procedure, (which is not advised due to the fact that somecircuit breakers may be in the off state prior to shutdown for some reason,and the difficulty in correctly identifying all of them may lead to errorswhen restoring power) instead of turning off the switch in the rear of eachdisk drive, is to wait until everything else in this section has been done andthen throw all the circuit breakers on the Maxc, Maxc-A and Maxc-B CircuitBreaker Panels, noting carefully the ones which are already off.MaxcPress middle blank button then type3301PM.With the left mouse button successively select the menu items "Power Off" and"Both".NOTE 4:(The message "Processor locked on" will appear.
