Power Down and Up Procedures for HIRES
I. Powering DOWN HIRES
-
Log on to honolii as user hireseng.
-
Check the 3.8-l dewar level:
nuu{hireseng}22: ln2
DWRN2LV = 100.521973 percent full
RESN2LV = 77.074471 percent full
TEMPDET = -120.123032 degrees (C)
Initiate a fill if DWRN2LV is less than 50% of capacity. This is most easily
done from the menu entry
HIRES Control Menu -> Initiate HIRES Dewar Fill.
-
Disable the alarm cron jobs running under the kics account on waialea.
This can be left to later if the power down is an emergency. Contact
the HIRES support astronomer if help is needed with this step.
-
Log on to 'hccdcrate'; use the menu entry Engineering -> Tip CCD Crate
or:
punaluu{lriseng}: telnet tserver1 3011
or
nuu{hireseng}: telnet hccdcrate
Disable power to the CCD at the VxWorks prompt: Call the HIRES support
astronomer for the login and the password if you do not know it.

-
Turn off the
CCD power supply switch
(the covered light switch under the
UPS on the right-side shelves in the HIRES Electronics Enclosure).
-
Turn off power to the main rack in the electronics enclosure. The power
switch is the large toggle switch behind the hinged rear cover on the rack.
-
Turn off power to the Varian ion pump power supply, located on the shelf
above the UPS.
II. Powering UP HIRES:
-
Turn on CCD power (the light switch; see above).
-
Turn on rack power (the rack toggle switch; see above).
-
Turn on ion pump power (on the shelf; see above).
-
Set the ion pump current gauge scale to 50 uA full-scale, and push the
reset button down for 2 seconds to start the device. Verify that the gauge
reading is dropping into this range, and that the light goes off; it may
be necessary to start in a higher range. The operating current is less
than 1 uA, so bring the scale down to 5 uA full-scale ultimately.
-
Check dewar levels via keywords ('ln2'). Try and read a raw encoder value
(s 'xdraw').
-
Re-enable the alarm cron jobs running on waialea.
