Withina segment bank, the specific segment to which a Model 5399

Remote Access Concentrator module is connectedis determined by

setting the segment selectionD IP switch on the module. For more

information,see “Se tting the Backplane Ethernet Segment” on page 2-3.

System 5000 Service Port Management

The service port,loc atedon the front panel of the chassis, provides a

switched serial communication link between the service port and any

module in the hub, including the supervisory module. By connecting a

terminalto this port, you can change the configuration parametervalues

for the Remote Access Concentratorinstalled in the hub.

Formore information, see “Connecting a Service Port Terminal”onpage

2-14,“Remote Access Concentrator Para meters” on page 2-18,and

“Installingthe Model 5399 Remote Access Concentrator” on page 2-3.

Firmware and Software

Firmware TheModel 5399 Remote Access Concentrator’sROM contains firmware

for performing power-upself-tests and loading operational code. A

non-volatileEEPROM stores the configuration parameters.

The Remote Access Concentrator can boot from theboot image in its

Flash memory or can boot an image received from a boot server on the

network.

ROM Monitor The ROM monitor isan interactive command interpreter that is used to

define basicconfiguration parameter values. All of the information that

theModel 5399Remote AccessConcentrator needsto bootan operational

image is defined using the ROM monitor and its command set. ROM

Monitor commands are issued from a terminal connected to the service

porton thehub chassis.When theRemote AccessConcentrator completes

itsself tests, the service port terminal displays the ROM monitor prompt.

Using the ROM Monitor commands (see Chapter 3), you can:
