Figure 3-9 Connecting the RXE-100 to the x440
With single-node configurations (that is only one x440 node in a two, four or
eight-way configuration), only one RXE-100 can be connected using one
Remote I/O cable as shown in Figure 3-9. In this configuration, all 12 slots in
the RXE-100 are available to the system. The use of two cables (for example,
for redundancy or performance) is currently not supported.
The RXE-100 ships with a 3.5 m Remote I/O cable to connect the unit to the
x440. This cable is long enough when the devices are in the same rack as
each other. For installation in an adjacent rack, use the optional 8m Remote
I/O cable kit.
In the 16-way configuration (that is two x440 nodes), only one RXE-100 can
be connected as shown in Figure 3-10 on page 82. Three Remote I/O cables
are used — two to connect the x440s to the RXE-100 and one to connect the
two x440s together.
