3U Bay 3U Bay
3U Bay 3U Bay
A22
(3rd) (4th)
(2nd) (1st)
Vertically adjacent bays can be electrically and logically configured so that one CS-
bus can service two bays with up to eight channels. The following configurations
are possible:
•
Four CS-buses servicing four bays of four channels each
•
One CS-bus servicing eight channels in vertically adjacent bays and two CS-
buses servicing two bays of four channels each
•
Two CS-buses servicing two sets of vertically adjacent bays of eight channels
each
See Table 5–3 for channel loading.

configurations Consists of adjacent 3U bays converted to 6U use:
3U Bay 3U Bay
6U Bay
A23
(2nd) (3rd)
(1st)
In the configuration shown, two 3U paths service the two upper bays and one 6U
path services the lower bay. The 3U-to-6U conversion can be in either the upper or
lower bays, or both. The following configurations are possible:
•
Two CS-buses servicing two bays of four 3U channels each and one CS-bus
servicing one converted bay of four 6U channels
•
Two CS-buses servicing two bays of four 6U channels each
See Table 5–3 for channel loading.
Channel loading Each CS-bus can handle up to eight channel loads. The above configurations may
be limited to fewer channels than indicated, depending on the channel loading. See
"Assigning Channel Loads" in Section 5.
Filler boards Unused 6U locations must contain a filler board. The RM5-6UF option provides one
6U filler board for this purpose and included with CSB3-E6U option.
