62 Encore — Installation and Service Manual
Section 2 — Installation
The original Encore Control frame part number 6100884xx is noncon-
forming and requires the crossover cable (174821600). The newer Encore
Control frame part number 6101000xx is conforming and uses a standard
Patch (pin-to-pin) cable (174821700).
The length of the cables (20.32 cm, 8 in.)provided is the maximum length
supported for cabling from the Encore Control frame to the Y connector.
Each of the cables connecting an Encore System Controller to the Y con
-
nector must be the same length. Redundant connections need to be made
within an area ≤ to the length of the two cables. See
Figure 38.
Figure 38. Redundant Cabling
The two Encore System Controllers must have identical hardware and soft-
ware configurations. The most common placement of redundant System
controllers are side-by-side in one Encore Control frame. However, the
redundant System Controllers can be in different Encore Control frames as
long as they meet the cable length and configuration requirements.
The customer supplied cabling from the Y connector to the device is not
specified but here are a few guidelines;
• Use the shortest cabling practical for the installation,
• When using RJ-45 to D type serial adaptors, put the adaptor as close to
the device as possible, ideally connect the adaptor to the device, and
• Use Cat 5e Ethernet patch (pin-to-pin) cabling with RJ-45 connectors
from the Y connector to either the device or the adaptor on the device.
