Platform ethernet (top)

The platform ethernet orginates in the.224 switch (at the bottom of the 10gb rack). it Currently has two outputs:

192.160.175.000 network

192.160.175.001 this is the .224 switch on the platform ethernet side..

gpib0 dewar monitoring on turret floor

192.160.175.010. gpib to ethernet in rfi box in rightmost blue rack on turret floor.
path. switch -> fiber -> pa9,10 behind pnt crate -> RP1.6 (repeater below c1 box) -> then RP1.5 -> C1.13,12C1.

gpib2: rfi hilltop monitor

192.160.175.012. gpib to ethernet in rfi shack (in osvaldo's box)
path: switch -> fiber -> da5 (in timing room) -> pa11,12 (check these) then to box under C1 (leftmost fiber)

platform1, is .001 on this net. You could plug into either the for repeaters before the gpib to ethernet to access it.

RP1: The repeater in the receiver room. (removed nov17)

RP1.rx5 -> B1.C1.13 -> B2.13 -> RP2.tx11 repeater in dome

RP1.tx5 -> B1.C1.12 -> B2.12 -> RP2.rx11 repeater in dome

RP1.tx4 -> B1.C5.7 -> TD8.

RP1.rx4 -> B1.C5.8 -> TD8.

RP1.tx3 -> B1.C5.9 -> TD4.

RP1.rx3 -> B1.C5.10 -> TD4.

RP1.tx2 -> B1.C5.11 -> TD12

RP1.rx2 -> B1.C5.12 -> TD12

RP2: The repeater in the dome:

Note: 12oct06: rp2 fails. we used a fiber barrel to jump port 11 input to port 12 input so the dewar monitoring would work. All the other ports won't work till we replace the repeater.

Notes.. PC6 doesn't have enough fibers for the platform ethernet to go to tertiary and the turret fixed
floor. We'll probably just run it to the tertiary. You can undo the jumper in B13 if you want it at the turret fixed floor.

Scramnet fiber routing.

The scramnet boards are a reflective memory system connected via fibers. It is a ring structure with a pair of cables entering and exiting each station (the order of the pair is
not important). The connection topology (at least on the fiber labels) are:

COR->DA->PNT->OBS->COR

obs was moved into the wapp room (my joanna's machine)

(before contrl/opr computer removed):

OPR->COR->DA->PNT->OBS->OPR

Datataking ethernet

The data ethernet for the vxworks datatking is a 10 Mbit ethernet coax (limited by the single board computer ethernet transceivers). The cabling order is:

switch under table that observer cpu sits on.

control, observer2, observer connect here as well as the bnc 10 mb cable

switch under observer -> cor -> pnt -> da -> pointing -> ??
