WP12510 FRS34002
I have installed the four Geist Watchdog 1250 rack mount units in the CDS computer racks at MX, MY, EX and EY.
At the end stations these units are mounted close to the top of the CDS front-end computer racks, forward facing (see attached photo of EY). The end station computer racks are located in the first room you enter from outside.
At the mid stations these units are mounted in the VEA computer rack, located roughly in the center of the VEA. All the internal roll-up doors are open, essentially making the whole building one very large room.
EPICS IOCs were created to read out these units, and their channels were added to the DAQ yesterday.
I have added an environment section to the CDS overview (see attachment) which provides visual alerts if any out-building sensor is out-of-bounds.
The LEDs show light_level (L), sound_level (S), temperature (T) and humidity (H).
In the example shown, the EX lights are on.
Providing the Geist units with a network connection to the ADMIN-LAN:
At the midstations, the ADMIN-LAN is provided by a fiber-to-ethernet converter box, originally directly connected to the PEM front-end computer IPMI port. This is now sent to a 4-port ethernet hub, which feeds the IPMI port and the Geist unit.
At EY it was possible to reconfigure sw-ey-stk(2) to give ADMIN 4 more ports, and remove 2 each from SLOW and FE. This required moving all four SLOW cables 4 ports to the right, which was done quickly with no impact to HWS, BRS, HEPI-PUMP.
At EX it was not possible to do the same, so here two unused SLOW ports (15,16) were reallocated the ADMIN.
To complete the install I removed the MY rack doors (front and rear) to make them the same as MX and improve front-end computer cooling (see trend).
