BVPU Configuration

Note Maximum of five BVPUs for CTX670 and a maximum of two BVPUs for CTX100 because of FCC Part 15 Electromagnetic Capability (EMC) emissions restrictions.

BVPU controls, indicators, and interface connectors are shown in Figure 6-10and described in Table 6-7.

BVPU Installation

1.Insert the BVPU (component side facing right) into the appropriate slot and apply firm, even pressure to ensure proper mating of connectors.

2.Attach the 10BaseT Ethernet connection to the LAN connector.

3.Connect a PC equipped with Maintenance Console Software (MCS) to the serial port according to the drawing below. A serial connection is necessary to establish the IP address of the BVPU. Once the IP address is established, maintenance may be conducted over the Ethernet port.

4.After installing the BVPU, gently pull it outward. If the connectors are properly mated, a slight resistance is felt.
