Assignments
There are three Plexus 9000 chassis: part number 85-3000, 85-3004 with
Midplane II and 85-3007 with Midplane III. 85-3004 and 85-3007 have a
high-speed fan shelf (85-3005). Each chassis has 21 slots for modules.
The SPs are always installed in physical slots 9 and 13 and the SF modules
are installed in physical slots 10 and 12. The other 17 slots are for I/O
modules.
IOMs installed in chassis 85-3000 can be DS-1 or DS-3 (triple) IOMs and
if unprotected can be installed in any slot. If the IOMs are protected, the
DS-3 protection slot is I/O-9 (physical slot 11). A DS-1 protection slot is
I/O-7 (physical slot 7). The protection scheme of the 85-3000 chassis is
illustrated in

Figure 6.1-3. Protection for 85-3000 Chassis (P413-AA)
Unprotected IOMs installed in chassis 85-3004 with Midplane II and
chassis 85-3007 with Midplane III can be installed in any slot. If the
IOMs are protected, the DS-3 protection slot is I/O-5 (physical slot 5) and
I/O-13 (physical slot 17) as illustrated in
. I/O-5 provides
DS-3 protection for I/O-1 to I/O-4 and I/O-6 to I/O-8 (physical slots 1-4
and 6-8). I/O-13 (physical slot 17) provides DS-3 protection for I/O-9 to
12 and I/O-14 to 17 (physical slots 11, 14-16 and 18-21). A DS1
protection slot is I/O-7 (physical slot 9).
