Proper Option 61C shut down procedure

[ReenaS]

What would be the proper way to power down a 61c? Would I begin with the individual cabinets and then main power breaker or vice versa?

i would turn off the processor selves fromthe front unless it's a dc switch, for a dc i would turn off all cab's fromthe back.. after cpu 0 and cpu 1 is off, if you need toyoucan shut down the ipe columns.. except for removing or moving a switch, i can't think of doing a power down. i always have the ipes powered up before the cpu.. then the cpus will see the network cards and do the down load.. if you power up the cpus 1st, you'll need to enxp all the xpe's thne enll the loops and bring up the pri's and amls, it is a pain if you need to bring up the conf dtr tds etc..

Just a word of warning here:

Be careful if you have older power supplies (NT6D41's for DC systems) in your shelves. We had to shut down, and follwed the manual exacty by shutting down the IPE shelves, then the cores, then the fans and main power feeds on the back of the columns. When we brought it back up, in the reverse order, we had 5 power supplies not come back. There is an issue with some of the switches on the old power supplies, and they fail when flipped.

If you have this issue, you can bypass the switch on the back side of the power supply faceplate for immediate resolution.

I would ONLY turn the system of using the switches on the back of the column.
