  • Page 85 • Chapter 5 - Memory Expansion Module (XVME-956/101) 5.5.3 Battery Replacement To maintain backup current to the devices, a good battery must be connected to J4 or J5 at all times. You can change one battery at a time. Figure 5-4 shows the J4 connector. (See Figure 5-1 for the location of the J5 connector).

The XVME-956/411 supports 10BaseT (Twisted pair) and 10Base2 (Thin-BNC) Ethernet, plus has an AUI connector for connection to external transceivers.

Default Jumper Configuration Function Default Jumper Position TERMINATION DISABLED DOWN BUS SIZE AUTO LEFT Termination The 10Base2 input (BNC) can be terminated on the XVME-956/411 card. This eliminates the need for the TEE fitting + BNC terminator at the end of the line, and is very convenient for simple two or three node nets.
