The RX7i rack can be used for all RX7i CPU and I/O configurations, including Series 90-70 I/O and VME modules. The RX7i rack accommodates two module types:
■ RX7i and Series 90-70 modules, which use a detachable field wiring terminal board. Each I/O module accepts up to forty AWG #14 (2.10 mm2) wires. The wire bundle is routed out to he bottom of the terminal board cavity, where a cleat is provided for a tie wrap to secure the bundle to the terminal board housing.
■ VME modules, which have varying methods of connecting to field devices.
Backplane connectors are spaced on 0.8" (20.3mm) centers to accommodate single-width and double-width RX7i and non-GE Fanuc VME modules.
The RX7i rack:
■ Supports a maximum of 17 single-width modules, which require 0.8" (20.3mm) spacing.
■ Accepts RX7i modules, VME modules, and some Series 90-70 modules. For a list of supported modules, refer to pages 2-13.
■ Provides slot sensing for Series 90-70 rack-type I/O modules. No jumpers or DIP switches on the I/O modules are required for addressing these modules. ■ Provides J2 backplane connectors to allow high-speed VME transfers of up to 64 data bits per cycle.
■ Accepts plug-in RX7i AC power supplies.
■ Supports power supply for higher current configurations.
■ Supports an optional cooling fan assembly (required for IC698CPE020/CRE020, IC698PSA350, or any of the single-width IC697Vxx modules).
■ Provides a 6-pin RJ-11 connector for connecting an I2 C serial cable.
The rack accepts a power supply in slot 0 and a CPU with Ethernet daughterboard in slots 1 and 2. The remaining slots can be used for one of the following I/O combinations:
■ fifteen single-width modules (with no double-width modules installed),
■ eight double-width modules, or
■ a combination of double-width and single-width modules.

Overall rack dimensions are 11.15" H x 19" W x 7.25" D (283mm x 483mm x 184mm). Slots are 0.8" (20.3mm) wide except the power supply slot, which is 2.4" (60.96) wide.
