Fred,you are right, I misread my systembuilder handbook. Two 2809 should do for two 2729s.
You should buy them for around 50 US$ used / refurbished. Philipp midrange.list@xxxxxxxxxx schrieb:
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 Fred Mitchell schrieb: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?-- This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing list To post a message email: MIDRANGE-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/midrange-l or email: MIDRANGE-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/midrange-l.
