It was finally time to hook up some phones and see if I could place a call.
The first part of the video shows the power-on procedure. Starting at the MCAM BSP, I turn on some breakers for minimal loading on the PSU, as well as the talk battery to the LCE because I want the filter cap to charge as the PSU come up. Afterwards, the first PSU gets turned on, but I don't do all three since I don't have enough load for their minimums yet.
Back at the BSP, I turn on the cooling unit. This provides enough load, so I fire up the other two PSUS.
While I'm up at the MSP, I turn on the two 10A breakers for the alarm battery supply. One is for the MCAM frame itself, the other feeds the 7ft frames. We see the alarm lamps at the end of the aisle and the FSPs come on at this point.
Next up is the breaker in the MCAM BSP that runs the cooling units for the MCNI and the DPCC. The DPCC cooling unit is shown starting up.
Next are the two breakers for MS 0. The recovery procedures manual says that the two right power converters should be started together, followed by the left -5V converter, and then the left +5V converter.
Then the breakers for ENET 0. The recovery manual states to first start the left converters together, followed by the right converters together.
Before I move on to the LGC, I need to turn on the breaker to the TME, and there turn on the breaker for the LGE cooling unit. The FSP of the LGE is shown as the cooling unit starts.
With the cooling unit started, I turn on the breaker at the MCAM first. In order to turn on the breaker at the LGE, I need to first turn on and hold the power converter in reset, and then flip the breaker in the FSP.
The breaker for the LCMs and RGs was next. Since the LCMs use a different style of power converter, all I had to do was turn on the breaker in the FSP for the LCA and the RG.
Lastly, the 3 breakers for the XA-Core were turned on, and the switch begins to boot.
With the XA-Core RTIF on the left, and a MAP terminal on the right, the switch bootup process is shown (sped up 32x with some pauses cut out, since it takes about 30 minutes)
Once the MAP terminal finally comes online, I log in and take care of setting the date and time. Then I move on to MAPCI.
I check the status of a few things on the message switch and the ENET to make sure it all came up properly, then I move to the PM section. I need to perform a LoadPM to get the LGC booted, followed by the LCM. Normally the switch would get around to this eventually on it's own, but by manually starting it I can speed it up. This process takes a while as megabytes of data are sent over a single 64k message switch link, so I sped up the video 32x.
As I looked through the list of working lines on the switch, it became apparent that most of the lines had been removed during the cutover process. As such, I would have to reconfigure some lines into the LCM I had turned on.
After unsuccessfully trying to make some new lines, I settled on finding some existing ones and moving them into the active LCM. Using the CLN command (Change LEN) in servord let me accomplish this.
I set to wiring up the two lines I had just configured in a temporary fashion, verifying I had dialtone along the way as I made connections. When I finish, I show the line cards which the phones will be connected to.
At that point, I'm ready to make the calls. I demonstrate one call in each direction.

The entire process from start to finish took about 3 hours in real time.
