128 Trinix NXT — Installation and Service Manual
Section 3 — Hardware Installation
Install the supplied “IFC” cables:
1. Connect the long cable from the FRAME IFC connection on the power
supply frame to the PS IFC connection on the main frame.
• The FRAME IFC connection is located in the lower right side of the
power supply frame (
Figure 68 on page 141 ).
2. Connect the short cable from the FAN IFC connection on the center
right side of the main frame to the FAN IFC connection in the fan
module section, which is above the Input and Output connectors.
• For an illustration of the location of the IFC connections, see
Figure 68 .
Note The IFC cables cannot be swapped. To prevent this, the cable for the Fan IFC
cable has a different connection than the Power IFC cable
Power Supplies for Asymmetrical Frames
Power supplies for TRX-NXT-128x256, TRX-NXT-256x512, and TRX-NXT-
512x1024 Routing switches are mounted in a separate chassis that requires
attaching the power supply cable to the DC Input connector on the Routing
switcher frame.
• The power supply frame can be mounted above or below the TRX-
NXT-128x256, TRX-NXT-256x512 Routing switcher frames.
• Do not obstruct air flow to the top or bottom of the TRX-NXT-
512x1024 frame. A 2 RU space should be kept free under the fan.
Note For more information about Power Supply connections with Asymmetric
frames, see Trinix Asymmetrical Power Supply Configurations
on page 227 .
Connecting and Configuring the Reference Settings
Follow these steps to connect and configure reference signals:
1. Connect the appropriate house reference signals.
Depending on the system, up to four independent sync references can
be used.
The SR-33000 Sync Reference / OPM board, the NR-33000 NIC/Sync/
OPM board, or (in TRX-NXT-512x512 units) the SR-33500 Sync Refer-
ence board can be used to lock the system to a Reference sync.
