Page 54 of 456 Preparing for installationNN43021-310 Standard 02.01 December 20076 Sending and receiving cables must be of equal lengths and as short aspossible.7 In order to optimize network FIJI cabling, mount the NTD35 networkmodules in pairs in the same column, one module on top of the other inthe middle tiers. The modules must be stacked in one contiguousequipment bay. The longest FIJI cable (NTRC48FA) is 8 m (26 ft),which is the maximum distance of the furthest network module from theCore/Net modules.8 The IPE modules can be located separately from the CPU and networkbay, by up to the maximum network cable length of 13.5 m (45 ft).9 Core/network modules can also be on top of each other in the first andsecond tier in multi-group systems.Cable routing guidelinesA system layout, preconfigured at the factory, is included in the software boxwith each system shipment. Before you route cables, refer to the “to-from”cable connections in the system layout. Note that there are a variety of cablelengths. Make sure you install the designated cable for each connection.Because the cable troughs (see Figure 12 on page 55) and spaces on the sidesof each module are within the EMI shielding of the system, unshielded cablescan be routed in those areas. The corner vertical channels in the rear of themodule are outside of the EMI shield. Cables routed in the vertical channelsmust be shielded, and must enter and exit the EMI-shielded area through I/Opanels and adapters.
