Motorola CPCI-6020 manual Hot Swap Support, High Availability Support, On-Board LEDs

Functional Description On-Board LEDs

4.10.8On-Board LEDs

The CPCI-6020 provides two LEDs visible on the front panel for status of CPU and Board Fail (BDFL).

zThe green CPU LED is lit when the DBB# signal of processor bus is active (hardware controlled).

zThe yellow FAIL LED is lit when the Harrier BDFL bit in the Miscellaneous Control and Status register is active (software controlled).

Refer to the Harrier Application Specific Integrated Circuit (ASIC) Programmer’s Reference Guide for details of the BDFL bit.

4.10.9Harrier Power Up Configuration Header

An 8-pin header provides the means to change some of the Harrier power up configuration settings. Refer to Chapter 3, Controls, LEDs, and Connectors for configuration settings controlled by this header. A shunt must be installed to change a setting. The default configuration setting (with the shunt not installed) is also given in that chapter.

4.11Hot Swap Support

The CPCI-6020 provides hardware to support the physical connection process and the hardware connection process of the full hot swap system model defined in the CompactPCI Hot Swap Specification. This hardware supports the hot swap of peripheral boards in standardized (non-high availability) chassis. Hot swapping of the CPCI-6020, the system controller, itself is not defined in the CompactPCI specifications. A description of CPCI-6020 support for system slot hot swapping is in the following high availability support section.

4.12High Availability Support

The CPCI-6020 includes support for system slot hot swap in Motorola’s chassis. This includes high availability (HA) features defined in the CompactPCI Hot Swap Specification as well as Motorola’s added extensions.

Standardized features include implementation of the BD_SEL#, HEALTHY# and PCI_RST# signals. Motorola extensions are described in the following sections.

4.12.1HSC Bridge Board Interface

The CPCI-6020 interfaces with a local bridge card which resides on the remote CompactPCI Bus. The bridge card is named local because it bridges down, in a hierarchical sense, from this CPCI-6020 local domain to the remote bus. Similarly there is a remote CPU card with a remote bridge card which bridges down to, and resides on, this local CompactPCI Bus.
