Meaning me as the moron...
I was trying to activate somebodies 11/23-RL02 system
this morning and had fun cabling it up, etc.
But I was not able to get the RL02 up.
I was able to:
Find all the power switches including the master.
Read the booting sequence from the terse manual.
Ensure that the RL02 was cabled to the CPU, and terminated.
Get the VT100 to run the bootstrap up to the disk load point.
Seat the pack and it's cover and re-close the drive.
See the load light come on.
Depress the load switch: The light goes off immediately.
Hear 15 seconds quiet of revving up.
The load light stays off.
We did Not see:
The load light ever flash or come back on.
The Ready light never comes on.
First thing : check the bulbs in the RL02 switches. The caps just pull
off, then the bulbs pull out (wedge-ended all-glass bulbs). If I need to
tell you how to test them, you haven't a hope of finding logic problems in
the '11 or drives :-)
In particular, make sure the fault lamp bulb is OK. I want to be sure the
drive isn't indicating a fault. In fact you might try powering down and
disconnecting the controller cable from the RL02. Then power up. The
drive fault lamp should come on (loss of the drive clock). If not, then
we ened to find out why not.
It sounds like the heads aren't loading. There is a mechanical lock on
the positioned to lock the heads for shipping. Make sure it's not
locked!. Then stick a pack in and take off the drive logic access cover
(4 captive screws on top, unhook it from under the drive cartridge access
door). Hookl the cover onto the back edge of the drive, then lift the R/W
module (in the middle), hook that on the side of its hole without
unplgging anything. You can now see the positioner and heads. Power up,
hit the load switch, and see if the heads move at all.
