Expanded (Multi-Chassis) Systems
Expanded Apex Plus systems require RG-59 or RG-6 coax Master Clock
connections in addition to the InfiniBand cables. Master Clock cabling is
shown for all systems in the following figures:
• 512 inputs ( Figure 9 on page 41 ),
• 1024 inputs ( Figure 10 on page 42 ),
• 1536 inputs ( Figure 11 on page 43 ), and
• 2048 inputs ( Figure 12 on page 44 ).
Refer to Table 2 on page 40 for cabling information.
As shown on Figure 5 on page 35 , each group of four Expansion (Infini-
Band) connectors, and each group of four Master Clock BNC connectors
correspond to one MX-34000 Matrix board. The three Master Clock Out
connectors are functionally identical, i.e., they can be connected to any
chassis.
Notes
1. Redundant InfiniBand and Master Clock cables (not shown in the
drawings) can be added if each chassis is equipped with a secondary
matrix board. In this case the Expansion B connectors would be used.
2. Only one CX-34000 Control Crosspoint board is required per system,
regardless of expansion.
3. Fiber Extenders cannot be used with the Apex Plus router.
4. If you are thinking of expanding the Apex router beyond the 1024
configuration, planning for expansion should be done before
purchasing. The Apex and Apex plus frames are different. For example,
the Apex symmetrical frame cannot be later expanded to a 2048x2048
configuration.
