Chapter 2 Provisioning

Chapter 2 Console Provisioning

2.1 Introduction

This chapter will go into the details of the specific provisioning and operation of the FRM220-NMC. Broken into

two chapters, this chapter outlines the procedures and functions when using the serial console for configuration.

The next chapter will outline the operation when using a network connection, including the Web based

management. For initial operation, until the TCP/IP settings are completed, a terminal connection to the Console

port is typically required.

All of the features and controls described in this chapter require the FRM220 chassis to have the NMC

(Network Management Controller) installed. The Management System is a collection of three control modes for the

FRM220. The simplest and most basic mode is "Console Mode". The terminal or console mode is a local control

which requires an VT100 based terminal and an RS-232 connection to the RS-232 console port of the NMC card.

Provisioning and monitoring are performed through a series of menus and menu selection items. All changes made

to cards through console mode are executed immediately or when escaping a menu and do not require any

separate 'save' operations. From the console mode, the initial network configuration can be accomplished. This will

allow remote network configuration to proceed from Telnet connection (remote console), web browser or any

network management software after compiling the enterprise MIB-II compliant file for FRM220-NMC. A MIB

browser provides another simple platform for the user to setup using the SNMP protocol remotely.

Prior to any initial use of the LAN interface on the NMC card, the configuration settings for networking must be

performed. These include the NMC IP address and subnet mask, the network's default gateway, the IP address of

any TFTP server that may be used to update the NMC firmware, and lastly the IP addresses of the management

workstations that will be managing the system via SNMP protocol. The front panel of the NMC card provides the

connections and indicators.

The DB9 Female connector is an RS-232 DCE connector designed to connect directly to a terminal or a PC

running terminal emulation software.

The 'ACT' LED will flash once per second when the NMC has successfully booted and is running. The 'STK'

LED will always be lit on the master chassis. If multiple chassis are cascaded, the slave NMC cards will have the

'STK' (stack) LED lit if the stack connection is normal. 'STK' LED will be off if the link to upstream chassis is broken.

The LAN connector is an RJ-45 designed for direct connection to either a HUB or DTE device (auto-MDIX

supported). The interface supports 10/100Base Ethernet auto negotiation. The 'LNK' LED will light to indicate the

Ethernet has a successful link and flash when there is activity on the Ethernet. The '100' LED will light to indicate

the Ethernet connection speed is 100M and will be off if the connected speed is 10M.

A unique feature of the NMC, the system can restore all the previous

settings in case some unexpected event

occurs such as the sudden power loss. After power is restored all the settings will be restored to each line card and

remote units that apply.
