EY ISC Electronics
This morning all power to SUS, SEI, HEPI, Timing, TCS and ISC was turned off (including all IO chassis). 
- We then placed a DC Supply Sequencer D1200757 in ISC Rack C1. This ensures ±24VDC is present prior to ±18VDC. 
- All AC power cords were rerouted on top of the racks. 
- Front end computers and IO chassis were restarted by Richard.
- Power was restored to all electronics (except TCS)
- Looked at RF signals coming out of RF Amplifier for both the 71MHz (17.5dB)and 24MHz (19dB).
