Slots and connectors are described on the following pages. Most modules occupy one slot. Some modules, such as CPUs and AC Power Supplies occupy two slots. PACSystems* RX3i System Manual Section 4 GFK-2314T Sept. 2019 Backplane 74 3.1.1.1 Universal Backplane TB1 Input Terminals The RX3i IC695 Power Supplies do not provide Isolated +24Vdc output power over the backplane. Terminals 7 and 8 can be used to connect an optional external source of Isolated +24Vdc, which is required for some IC693 and IC694 modules as listed in the table, Module Load Requirements, Section 4.2. These terminals accept individual wires from 14 to 22 AWG. If modules that require Isolated +24Vdc are installed in an Expansion Backplane instead, an external Isolated +24Vdc power supply is not required. Terminals 1 through 6 are not used. 1 – 6: not used 7: Isolated +24VDC In 8: Isolated Ground 0 1 TB 1 1 8 Slot 0: Connector for RX3i IC695 Power Supply only Figure 59: TB1 Terminal Detail 3.1.1.2 Slot 0 The leftmost slot in a Universal Backplane is slot 0. Only the backplane connector of IC695 Power Supplies can be installed in slot 0 (note: IC695 Power Supplies can be installed any slot). However, 2-slot wide modules that have right-justified connectors, such as the CPU310, can be plugged into slot 1and also cover slot 0. The CPU is referenced for configuration and application logic by the leftmost slot occupied by the entire module, not by the slot the physical connector is located in. For example, if the CPU has its physical connector inserted in slot 3, the module occupies slots 2 and 3 and the CPU is referenced as being located in slot 2. A double-wide CPU may therefore be located in slot 0 with its backplane connector inserted in slot 1. 3.1.1.3 Dual-Connector Slots PACSystems* RX3i System Manual Section 4 GFK-2314T Sept. 2019 Backplane 75 Dual-connector slots are identified as follows: CHS016: 0 through 15 CHS012: 0 through 11 CHS007: 0 through 5 They have two connectors, a connector for the RX3i PCI bus, and connector for the RX3i serial bus. Each of these slots can accept any type of compatible module: IC695 Power Supply, IC695 CPU, or IC695, IC694 and IC693 I/O or option modules. Provided the Hot Insertion and Removal procedure described in Section 2.6.4.1 is carefully followed, I/O and option modules in a Universal Backplane may be removed and replaced without powering-down. 10 Connector for PCI Bus Connector for Serial Bus Figure 60: RX3i Universal Backplane Dual Connector Slot for PCI Bus & Serial Bus PACSystems* RX3i System Manual Section 4 GFK-2314T Sept. 2019 Backplane 76 3.1.1.4 Expansion Slot (Slot 12 or Slot 16) The rightmost slot in a Universal Backplane has a different connector than the other slots. It can only be used for an RX3i Serial Expansion Module, IC695LRE001. An RX3i 2-slot module may not occupy this expansion slot. The 7-slot CHS007 rack does not provide an expansion slot, or support the LRE001 Serial Expansion Module. 11 12 E X P A N S I O N Figure 61: Expansion Slot Connector shown at Slot 12 3.1.1.5 Slot 6 of 7-Slot Rack PACSystems* RX3i System Manual Section 4 GFK-2314T Sept. 2019 Backplane 77 In the CHS007 seven-slot rack, slot 6 has one RX3i PCI connector and can accept only IC695 single-width I/O or option modules. 5 6 Figure 62: Slot 6 of IC695CHS007 3.1.2 Module Locations in a 12- or 16-Slot Universal Backplane ▪ IC695 Power Supply modules may be installed in any slot. DC Power Supplies IC695PSDx40 occupy one slot and AC Power Supplies IC695PSAx40 occupy two slots.
