1186.0. "Clock cable is blocking drive access" by KAOT01::C_MUTCH (Canadian Customer Service Support) Fri Apr 25 1997 11:56

 Question, 

  Does anyone know if it is possible to re-route the clock ribbon cable in the
back of an 8200.  One of our customers' is complaining that it blocks access to
the 2nd internal disk drive, making it impossible to pull out without removing
the cable and thereby making it necessary to power down the system. 
(see diagram below) 

 He wants to remove these drives on a regular basis to perform disk to disk
backups on another system.  Told him to this is not a good plan but anyway...
the design of this box seems to have overlooked the placement of these drives.


(I knew someone would eventually complain about this cable route)

Regards, 

Chris

Chris,

I'm surprised nobody has replied to this note.  I complained about 
this ribbon cable when I had a "TurboLaser Customer Audit Team" down 
at an insurance company site in Hartford.  It made little sense to 
have a disk drive slot available if you can't get to it.

The next 8200 that arrived on site had the cable re-routed and the 
disk drive was accessible.

My next question is: Is there an ECO that covers this cable reroute? 
Obviously, the build orders to manufacturing have changed.  Can the 
field get some details on the parts/rework required to implement this 
change?

Hello,

I'm not sure that why there were NO reply from Engineering.

>My next question is: Is there an ECO that covers this cable reroute? 

Yes, there is an ECO to recess PCB header for this cable.

You can replace whole center plane assy(70-31086-01) with ECOed parts 
and send it for ECO. I post an ECO documentation in next entry.

Hope this helps.
