Expanded (Multi-Chassis) Systems
Standard Apex Models
With a standard Apex chassis, 256 x 256 frames can be connected to form
512 x 512, 768 x 768, or 1024 x 1024 systems. The frames are connected by
four-meter (13 ft.) InfiniBand cables.
Note The InfiniBand cables cannot be longer than four meters (13 feet).
Figure 6 on page 38 shows a fully expanded (1024 x 1024) system with 6
InfiniBand expansion cables. Smaller systems will require fewer cables (see
Table 1 on page 38 ); the connector numbering scheme remains the same as
that shown for the large system. As shown in Figure 5 , each group of four
InfiniBand Expansion connectors correspond to one MX-34000 Matrix
board.
Expanded Apex systems with more than one chassis require RG-59 or RG-6
Master Clock connections in addition to the InfiniBand cables. The three
Master Clock Out connectors are functionally identical, i.e., they can be
connected to any chassis. See
Figure 7 on page 38 . As shown on Figure 5 on
page 35 , each group of four Master Clock BNC connectors corresponds to
a Matrix board.
If two or more frames of a multi-frame standard Apex system must be
located more than four meters apart, 2 each model APX-FBR-EXT Apex
Fiber Extenders must be ordered for each remote chassis. Refer to Fiber
Extenders (Standard Apex Only)
on page 45 .
Apex Plus Models
If a 2048 x 2048 system is required (or later expansion to that size is antici-
pated), the Apex Plus frame type is used. Apex Plus frames have either
input boards only or output boards only. For a 2048 x 2048 system, eight
Apex Plus frames would be needed: four with 512 inputs each, and four
with 512 outputs each. Systems may be asymmetrical if desired (having an
unequal number of inputs and outputs).
The illustration in Figure 8 shows a fully expanded (2048 x 2048) system
with 16 InfiniBand cables (optional redundant cables are not shown).
Smaller systems will require fewer cables; the connector numbering
scheme remains the same as that shown for the large system.
Note The InfiniBand cables cannot be longer than four meters (13 feet).
