Re: Problems configuring a 170

First of all, appologies as my original message seems to be on here multiple 
times.

Thanks Phillip.  Now I can see that an extra IOP is needed in E07.  However, 
looking at the system builder a #2809 will allow the second #2729 in E03.  Am I 
wrong?




Hello Fred,



you need to have an additional card to control that second (or third) PCI-Bus.
This is called an MFIOP (Multi Function IOP, or simply IOP).
In a 170 system this is an FC 2809 or 2824 (this depends on the type of 
expansion you have, the 7101 has a 2809 as base controller in slot E10 and the 
7102 has a 2824 as a base in slot E10).
Both accept a second IOP in slot E07, which can be either a 2809 or a 2824.
The first IOP card in slot E10 controls slots E08, E09, E13 and E14, while the 
second one controls E02, E03, E11 and E12.
If you have a 2809 in E07, only one 2729 is allowed in the expansion box.
The 2824 is a high performance IOP, which allows for a second 2729 in a 
7101/7102 expansion. The slots for the two 2729 have to be E03 and E09 as you 
already know.

Hope this helps,
Philipp

I have a 170 #2291 with a #7101 expansion cage.  There is a #2729 Magnetic 
media controller in slot E09 which I have been using for a while and is OK.  
I have today added another #2729 in slot E03 but I cant get the system to 
recognise this.  I have moved the old card from E09 to E03 and put the new 
card in E09.  The new card is recognised and I can use the tape drive but the 
old card in E03 is still not configured.  Does anyone have any ideas how I 
can force this to be configured?
