DELQA MAINTENANCE AIDS
Maintenance Operation Protocol (MOP)
In normal mode, the DELQA implements MOP functions in response to -the following remote console messages from other nodes on the Ethernet.
• Request system ID message - The DELQA responds by transmitting its current system 10 message.
• Remote boot trigger instruction - The DELQA may respond to a trigger instruction only if option switch S4 is open to enable remote boot. The instruction can be implemented only if the host system has the appropriate boot ROM.
• Loopback request message - The DELQA will respond to a loopback request message.
The DELQA also transmits its current system 10 parameters automatically every 8 to 10 minutes.
For more information, refer to the DECnet maintenance operation protocol (MOP) functional specification.
IEEE 802.3 Network Support
In normal mode, the DELQA implements IEEE 802.3 logical link control messages when they are received on a null Link-layer Service Access Point (LSAP) within an 802.3 standard local area network.
These messages can be used to interrogate and test many link layer service points per node. Therefore, IEEE 802.3 logical link control messages, which are received on a non-NULL LSAp, are passed on the the host system as normal datagrams.
For details on this message format and protocol, refer to the ANSI/IEEE Draft International Standard 802.2 Logical Link Control.
DELUA INSTALLATION DELUA ETHERNET UNIBUS ADAPTOR
General Description
The DIGITAL Ethernet large-scale-integration UNIBUS adaptor (DELUA) is a data communications controller that is used to connnect UNIBUS-based processors to the Ethernet ntitwork or Ethernet-compatible networks.
Reference Documentation
Refer to the following manuals for more information on the DELUA adaptor.

Ethernet Installation Guide DELUA Adaptor Components List
The following list describes the parts supplied with each DELUA adaptor and how to unpack and inspect them.
• Static Discharge System Setup
Unpack a VELOSTATTM static discharge system, CD kit A2-W0299-10.
Unfold the VELOSTATTM mat.
Attach the 15-ft ground cable to the mat snap fastener.
Attach the 15-ft ground cable alligator clip to a good electrical ground point in the host computer.
Attach one end of the grounding strap to the wrist and the other end to a convenient of the mat.
• Unpacking and Inspection
CAUTION
The DELUA M7521 module and the UNA bulkhead assembly must be unpacked and inspected on a static discharge system mat.
Inspect the unopened DELUA shipping container and check it for dents, holes, or crushed corners.
Open and unpack the shipping container, and inventory the contents against the DELUA components parts diagram.
Inspect the DELUA module for shipping damage. Refer to the Site Prepara-tion/ Installation Guide for damage reporting.

DELUA INSTALLATION Device Placement
The DELUA adaptor requires a hex-height small peripheral controlfer (SPC) backplane slot. Any SPC backplane (DDll-B, Rev E or later) can accept the DELUA adaptor module.
To prevent adverse bus latency, the DELUA adaptor should be placed on the UNIBUS conductor before all devices that have a lower DMA transfer rate and before all UNIBUS repeaters.
Installation Procedure
The DELUA installation procedures are detailed in the installation flowchart (Figure 1). If additional information is required refer to the following documents.
