PMF CRU Pathways Within One Enclosure
PMF CRU Pathways Within One Enclosure
The router in a PMF CRU provides pathways to slots 51 and 53 (X fabric) or slots 52
and 54 (Y fabric). It also provides a pathway to the PMF CRU in the opposite fabric as
well as other destinations of no concern to this discussion. The examples in this
section are of the X fabric.
The SEB router (not shown) in slot 51 connects the PMF CRU to all ports on the SEB.
The heavy lines in this figure shows pathways from the router in PMF CRU 50:
•
Through SEB 51 to the Group 52 IOMF CRU
•
Through SEB 51 to Group
•
To slot 53
PMF CRU Pathways Within One Enclosure: One PMF CRU
Removed
When you remove a PMF CRU from an enclosure, the SEBs or adapters in that
enclosure can no longer communicate with a router that should be in slots 50 or 55.
The heavy lines in this figure shows that with the PMF CRU in slot 50 removed, slot 53
cannot communicate with:
•
Group 52 (and the other I/O enclosures)
•
Group 01
