Downline Load Does Not Start

The following sequence of messages appears on the console terminal at various time
intervals:

Local –953– [IP] Attempting to locate load host, [ETHERNET]
Local –953– [MOP] Attempting to locate load host, [ISO8802]
Local –953– [MOP] Attempting to locate load host, [ETHERNET]
Local –951– network access server will retry operation in n seconds

Problem

Load hosts not responding to the DECserver 700 downline load request within the
allotted timeout period.

Correction: Copy the error message exactly as it appears on the console terminal
display and notify the network manager. For more information, refer to the Network
Access Server Problem Solving
 manual.

7.7 Seven-Segment Display Codes

The following page lists and describes the codes that will be displayed during the
server internal self-test when the DECserver 700 goes through a power up and ini-
tialization.
