panels in a single daisy chain. The maximum length of each SPP/SFE daisy
ch
ain segment between panels is 3’ (1m). Terminate the drain wire on the
ground termination points on the rear of the SPP/SFE
•
If the redundant daisy chain is desired
, connect the “OUT” of each of the last
panels in the daisy chain. Max length of this cable
is 25’ (11m). Redundant
daisy chain connections can only be made between panels served by the same
DCP or MCP.
•
Another termination option is to terminate the Control Bus Cable using S110 P4
plugs (for connections to SPPs or between SPPs). Leave enough drain wire out
the back of the P4 plug to connect it to the ground termination point.
If using the MCP RJ45s and SPP S110 Blocks to Terminate Control Bus Cables…
•
Only use the RJ45s on the front of the MCP. Do not use the S310s on the rear
of the panel. You can use the supplied S310 stuffer caps to cover the unused
S310 to prevent connections to these ports.
•
Plug in RJ45 plug end of the Control Bus Cable into RJ45 outlet on the front of
the MCP
•
Terminate other end of the Control Bus cable to the “IN” S110 port on the first
Patch panel in the daisy chain. Use T568A wiring scheme. Terminate drain wire
to ground termination point. Maximum cable length is 50’ (14m)
•
Terminate cable to “OUT” S110 block of the first panel in the daisy chain.
Terminate th
e other end of this cable to “IN” S110 block on the second Patch
panel in the daisy chain. The max length of this cable is 3’ (1m). Terminate the
drain wire on the ground termination point
•
Continue this daisy chain termination method for remaining panels (max 5
panels per single daisy chain, up to 10 for the redundant daisy chain)
•
If the redundant daisy chain is desired
, connect the “OUT” S110 blocks of each
of the last panels in the daisy chain. Max length of this cable is 25’ (7.6m)
If using the MCP RJ45s an Angled Panel or Fiber Enclosure RJ45 Bus
Connections
•
Use a shielded patch cord to connect the MCP RJ45 port to the IN port of the
panel
•
Do not reuse the S310 ports on the back of the MCP
•
Daisy chain an additional 4 panels (Connect OUT port from one panel to IN port
on the next panel)
•
If the redundant daisy chain is desired, connect the OUT port of the last panel in
a group to the OUT port of the last panel in the next group
Rule for Termination of Control Bus Cable in a Large Patch Zone:
