Full duplex operation in both 10/100 modes • Auto negotiation capability on all ports The CP945FP-12 and RM945FP-12 are fully integrated 12-port Ethernet switches with front panel I/O, designed to support the low-cost requirements of unmanaged switch applications. DDC No. Rx-URMH 122 Rev A...
Switch, Front Input/Output 1.1 Key Features As with all CompactPCI products from RAMiX, the CP945FP-12 module offers Hot Swap insertion capability for higher reliability and rapid service. The RM945FP-12 is a standalone switch and will work independently of any operating system. On power-up, the switch will automatically boot up and begin switching in Layer 2 mode without any input from the operator or host central processing unit (CPU).
Hardware Reference Manual CP945FP-12 CompactPCI, RM945FP-12 VME, & RM948 With Embedded Layer 2 Switch, Front Input/Output 2 Theory Of Operation The switch architecture is illustrated in the block diagram below. Total port count is achieved by combining two ZarlinkMDS 108 8 port fabrics via their uplink.

DB25 to RJ45 connector, see details in section 3 Handling and Installation. In default configuration, the CP945FP-12 and RM945FP-12 switches deliver a fully auto-configuring interconnect. Each port will negotiate speed and duplex with the connected interface. Once a link has been established, incoming packets are examined and the source MAC address added to the table associated with that port.

The contents of the SROM can be altered using a standard parallel port and PC. Contact RAMiX to receive a copy of the programming tool (for Windows 95/98 and NT). There is no charge for this program.
3.4 Cable Adapter Pin Outs Both the CP945FP-12 and RM945FP-12 are designed for use with a female RJ45 to male DB25 cable adapter. The cable adapter, RAMiX part number 06-0714025, is illustrated below, and can be wired using the DB25-1 and DB25-2 cable pin outs shown below.
4 Front Panel Connectors and Indicators 4.1 CP945FP-12 and RM945FP-12 The CP945FP-12 and RM945FP-12 use an identical front panel—face and side illustrations below not to actual size. The RJ45 connectors have 10/100BaseTX network connections. They are wired per industry specification.
