Connect to CrewNet
Connect your CrewCom system's devices via their available CrewNet RJ-45 Copper or duplex LC Fiber ports.
Important!
Device port connections must match your CCF's system diagram in order to operate. Pliant
recommends making all cable connections from the CU to other CrewCom devices prior to powering
on the system. However, CrewCom devices (such as RTs) that are already present in the CCF may be
connected or replaced while the system is operating. When hot-swapping devices, Pliant
recommends waiting at least 10 seconds between disconnecting and reconnecting the device.
How to Connect CrewNet to Hubs
When your system includes a Copper or Fiber Hub, it should also be connected to CrewNet via its available CrewNet
ports.
CrewNet Connectivity
RJ-45 Copper Ports
- Use the supplied 6.6 ft. (2 m) Cat 5e cable, or your own Cat 5e (or greater) cable (up to 330 ft.
(100 m) in length). Any CrewCom device connected to CrewNet via a Cat 5e (or greater) cable will receive Power Over
CrewNet (PoC) via the CrewNet port. (See
"Power Over CrewNet" on page 15
for more information.) In some
situations, there may be too many connected devices or the cable lengths may be too long for the PoC to adequately
power all devices, and this will be indicated with the NET PWR LED lighting red. To ensure best performance,
especially with larger CrewCom configurations and longer cable lengths, Pliant recommends utilizing the supplied
48VDC power supply (PPS-48V-02) to locally power each Hub. However, powering a Copper Hub and the devices
connected to it via PoC may be advantageous in some smaller configurations. See
"Power Over CrewNet" on page 15
for more information.
Fiber (Optical) Ports
- For a fiber CrewNet port, a Single Mode Fiber cable (duplex LC connector) will be required (up
to 32,800 ft. (10,000 m) in length). Any CrewCom device connected to CrewNet via fiber port must receive power via a
Pliant 48VDC power supply (PPS-48V-02 included with Hub; sold separately with all other devices).
