It must reside in the expansion connector on the right end of a Universal Backplane. 2.6.7.1 Module Installation L1 N PE L N/PE L1 PE L2 PACSystems* RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 69 This module may NOT be hot-inserted in the backplane; power must be removed before installing or removing the Bus Transmitter Module. Figure 55: LRE001 Front View Insert the Serial Bus Transmitter Module straight into its slot as displayed in Figure 56 below. This module does not have the same pivoting and latching mechanisms as other RX3i modules. Tighten the two captive screws in the corners of the module. Recommended torque is 0.5 Nm (4.4 in-lb) maximum. Figure 56: LRE001 Attachment Using Captive Screws 2.6.7.2 Expansion Cable Installation Subsequent backplanes in the system are linked by expansion cables as described in Section 5:. The expansion cable may not be attached or removed while the expansion rack has power applied.
