The Remote Access Concentrator boots from the defined preferred load

host. If the preferred load host is not defined or does not respond, the

Remote Access Concentrator optionally broadcasts on the Ethernet and

loads from the first host that responds, if the Load Broadcast flag is set.

To initiateloading,theRemote Access Concentrator sendsa load request

message to the selected host. After receiving a response, the Remote

Access Concentrator loads its operational code to RAM. When loading

iscomplete,ittransferscontroltothenewly-loadedprogram.TheRemote

Access Concentrator displays a symbol on the service port terminal for

each data block received during the boot.

When the Remote Access Concentrator begins to boot, it displays the

load server host’s Internet address. If the unit does not boot successfully

after several attempts, it displays a boot attempt failed message; if the

unit has opened the boot fileand an error occurs during the boot process,

it displays a boot error report on the service port terminal and returns to

the ROM Monitor. The boot error report can help determine the cause of

the boot failure (see “Boot Error Report” on page 4-8).

During a boot, the service port terminal may display four possible status

symbols: “.” indicates received data blocks, “?” indicates unanswered

requests, “*” indicates transmission errors, and “! ~XXXX~” is a status

word from the Ethernet chip on the Annex indicating a serious problem

with the Ethernet connection (if this symbol appears in your boot

command display, contact technical support).
