 +===== Startup / Shutdown Procedure =====
 +
 +**Attention:** This section describes how to power off the APS/Eta lab systems in the event of an emergency. Please follow the directions as closely as possible to ensure a correct, safe shutdown.
 +
 +==== Controlled Shutdown ====
 +
 +When the power goes off, or another reason arises to shutdown the network, the following order of shutdowns should be observed unless there is a sense of urgency where the battery power may run out soon, then skip the workstations and shut down the servers first. No harm will occur to the workstations.
 +
 +=== Workstations ===
 +
 +In no particular order:
 +
 +  * enki
 +  * anubis
 +  * horus
 +  * ea
 +  * bast
 +  * set
 +  * imhotep
 +
 +=== Servers ===
 +
 +The servers should be shutdown in the following order:
 +
 +  - amonra
 +  - isis
 +  - osiris
 +
 +=== Shutdown Instructions ===
 +
 +If the computer is a workstation, it can be shutdown by powering on the monitor and selecting the 'Shutdown' option in the user interface. The machine will probably show either a graphical or text based shutdown. At the conclusion of shutdown, the machine will either power itself off or inform you to do so.
 +
 +**Note:** The following also works on workstations.
 +
 +If the computer is a server, you will have to login as the `root` user or, alternatively, you can login as yourself and use the //su// command. After you become root, run the following command: ''shutdown 0''. The machine will show a text-based shutdown as it stops all services. At the conclusion, it will either power itself off or prompt you to do so.
 +
 +==== Fast Shutdown Instructions ====
 +
 +If the computers, for whatever reason, need to be shutdown quickly, observe the following procedure:
 +
 +  - Find the keyboard for the computer.
 +  - Hit the keys Ctrl-Alt-Print Screen-S at the same time.
 +  - Hit the keys Ctrl-Alt-Print Screen-U at the same time.
 +  - Hit the keys Ctrl-Alt-Print Screen-O at the same time.
 +
 +If the computer does not start shutting down after a few seconds:
 + 5. Hit the keys Ctrl-Alt-Print Screen-L at the same time.
 +
 +==== Bring up the Network ====
 +
 +Start the computers in the following order.
 +
 +  - osiris (wait for it to finish before continuing)
 +  - isis
 +  - amonra (see note below)
 +  - ea
 +  - set
 +  - imhotep
 +  - enki
 +  - anubis
 +
 +**Amonra** requires a monitor to be plugged into it to complete its bootup. Once it has restarted, the monitor can be reconnected to imhotep.
 +
 +==== Contact ====
 +
 +If there is a problem during either the shutdown or restarting of the network, please contact Matt Mix:
