We have a multi-machine highly-available ArcGIS Enterprise deployment, deployed on premises. When our infrastructure team does server patching and needs to restart all of the machines, what is the proper shutdown/restart order to avoid issues?

Preferably, the dependent machines would be shutdown while restarting the file server (or at least the services stopped for those components), then brought back up after the file server becomes available on the network again.
Yes, that order makes perfect sense; in reality steps 1, 2, and 3 in shutdown can be combined as well as 3 and 4 in startup. Otherwise hosted services may take a bit to regain access to the relational data store.
In terms of Portal for ArcGIS, you want to make sure you shutdown the standby to avoid failover (if doing things manually) or stagger the restart times between primary and standby if scheduling automatically. This will keep things from becoming split-brained as the machines start-up; primary will be recorded in the HA configuration file so start-up should be consistent when it comes back online.
But I'm unsure what the whole procedure should be. Do all of the components need to be shutdown, and then only started after the file server has been fully restarted? Or can the components be left running, and then just restarted after the file server is restarted?
You need to worry more about shutdown process with the MediaAgent if it hosts DDBs as the DDB can be corrupted if the MediaAgent is not shut down properly:

A shutdown happens when Congress fails to pass some type of funding legislation that is signed into law by the president. Lawmakers are supposed to pass 12 different spending bills to fund agencies across the government, but the process is time-consuming. They often resort to passing a temporary extension, called a continuing resolution or CR, to allow the government to keep operating.
Lawmakers warned that a shutdown could rattle financial markets. Goldman Sachs estimated that a shutdown would reduce economic growth by 0.2% every week it lasted, but growth would then bounce back after the government reopens.
The Supreme Court would be unaffected by a short shutdown because it can draw on a pot of money provided by court fees, including charges for filing lawsuits and other documents, court spokeswoman Patricia McCabe said.
Funding for the three special counsels appointed by Attorney General Merrick Garland would not be affected by a government shutdown because they are paid for through a permanent, indefinite appropriation, an area that has been exempted from shutdowns in the past.
The longest government shutdown happened between 2018 and 2019 when then-President Trump and congressional Democrats entered a standoff over his demand for funding for a border wall. The disruption lasted 35 days, through the holiday season, but was also only a partial government shutdown because Congress had passed some appropriations bills to fund parts of the government.
The purpose of the shutdown division is to manage utility interruption notifications along with coordinating communication to facilities coordinators affected by emergency, planned and emerging shutdowns of utility systems as well as notifications of fire alarm testing and crane lifts.
The Shutdown Staff maintains a list of building Facility Contacts, as well as OPP employees to be notified of shutdowns. The customers are notified based on a need to know basis for the building. The OPP employees are notified in an effort to coordinate their work during this same time frame.
In the event of an EMERGENCY utility shutdown that could result in danger or to prevent further damage and perform repairs, contact one of the shutdown staff immediately. The hours and contact information are below.
Stopped Funding to Border Communities and Interior Cities: DHS provided over $770 million this year to support border & interior communities to cover costs associated with sheltering migrants in their cities. Recipients may be unable to draw down on a portion of the funds, and no new awards will be made under a shutdown.
Normally you can indeed simply shutdown a box without any problems. Just to make sure, I would connect via SSH to the box and use 'request restart system" to make sure everything was written to the harddrive. The box will do a reboot and then I would poweroff it.
It runs through the basics of the EVM and BQ Studio. One of the manipulation that the guy says to do is to apply a voltage at the PACK pin, or press the S1 switch (with batteries connected) in order to wake the IC up from shutdown. Is it the only way to wake the IC up? There is not much about the state of the IC when it boots from scratch in the TDS.
I am designing a wireless product that will eventually be stored and transported. The user will not have access to the batteries, so they are always connected. It is a 2S LiFePO4 configuration that can be charged via a charger. That said, I want to make sure the battery will not discharge in the fuel gauge when the product is stored or transported, so I implemented a magnetic switch to toggle between the operational and storing modes. So with that switch, I would like to connect the PACK+ to the load, as well as waking up the fuel gauge from shutdown.
I don't need the OV protection since my charger takes care of that. Also my batteries have integrated OV and UV protections. So the CT52AN is the magnetic switch that latches when a magnet comes near (putting the product in operation mode). The PACK pin is connected to VC2 pin through the 5 ohm resistor so that the BQ wakes up. When the user swipes the magnet again, the switch latches off and the BQ goes back to shutdown. My question is: is it a problem to have a voltage on VC1 when the IC is in shutdown? Will there be a lot of leakage through VC1?
When the chip is in shutdown mode and VC1 is at 3.2V (VC2 not connected), i get less than 1uA going inside. So thats OK with me. That is the state I want to be in when I am in shipping and storing mode. So I basically disconnect the 2P port of the battery pack and after there is only 1P connected to VC1. I also noticed that if VC2 is connected to PACK at this point, current will leak from VC1 to PACK from the internal mosfet's body diode. That current is over 500uA, so I need to avoid that. I need to disconnect VC2 from PACK when shpping and storing the product. I'll look after that.
How about shutting the system off? Well, the PXI code can, on exit, reboot itself. Just before that, it could send a TTL signal to the Power Strip that says "Shut off the power in 5 seconds" (or however long it takes to finish the shutdown and restart the boot process).
With a possible government shutdown less than a week away, defense leaders say the nation will remain protected. But service members may end up doing that defense work without being paid. Elsewhere, training operations could be curtailed, which will affect long-term readiness. Efforts to support Ukraine may also be hampered.
"A shutdown ... puts the government on a complete standstill," said Deputy Pentagon Press Secretary Sabrina Singh during a discussion today with the Pentagon press corps. "[But] the U.S. military is going to continue to do its job and protect our national security interests and ... those of our allies and partners as well."
In Europe, efforts under "Operation Atlantic Resolve" provide increased troop rotations and equipment to the European theater to help maintain security there. Pentagon officials have said they expect to be able to maintain much of that effort through a government shutdown. But there will still be some effects felt, Singh said.
When it comes to supporting Ukraine, Singh said already approved funding means the U.S. could still offer more equipment and support as needed. But a government shutdown could affect the department's ability to actually draw down that equipment from stocks and get it to Ukraine.
