What is an MCC Card?

A Management Communications Controller (MCC) card is a processor circuit

card assembly (CCA) that administers and provides diagnostic connectivity to all

of the Digital Subscriber Line (DSL) cards in a HotWire 8600 or 8800 DSL Access

Multiplexer (DSLAM) chassis. It acts as a mid-level manager and works in

conjunction with a Simple Network Management Protocol (SNMP) network

management system, such as Paradyne’s DCE Manager for HP OpenView, via

its Local Area Network (LAN) port. It gathers operational status for each of the

DSL cards and HotWire Remote Termination Units (RTUs) and responds to the

SNMP requests (via PROXY ARP). It also supports a serial port for local or

remote terminal access.

!HANDLING PRECAUTIONS FOR

STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive components from damage

due to electrostatic discharge (ESD) during normal operation. When

performing installation procedures, however, take proper static control

precautions to prevent damage to equipment. If you are not sure of the

proper static control precautions, contact your nearest sales or service

representative.

Planning the MCC Card Installation

Review the following list to help plan for the installation.

Obtain the applicable cables; refer to the next section,

Cables You Need

Make sure the HotWire DSLAM chassis is installed and power is supplied to

the chassis.

Determine the type of network management you will be using to monitor and

maintain the DSL cards.

— Management via an SNMP network management system or to a remotely

connected asynchronous terminal via a telnet session over the

LAN-connected diagnostic network

— Local Network Management via a directly connected terminal console or

computer

— Remote Network Management with a remotely connected asynchronous

terminal or a remotely connected SNMP manager via a dial-up modem

8000-A2-GN11-10 June 1997

-After the MCC card is installed, there are configuration instructions that must

be performed before you can begin to use the MCC card for network

management. Refer to the

HotWire Digital Subscriber Line Access

Multiplexer (DSLAM) User’s Guide,

Document No. 8000-A2-GB20, for more

information.

Cables You Need

The following cables and connectors are used with this product:

HAn 8-pin modular CAT5 (UTP5) unshielded twisted-pair cable for connection

from the HotWire DSLAM Management MCC port to a 10BaseT hub

connector (connected to an SNMP management system network).

HA serial cable (provided with this product) for connection from the HotWire

DSLAM SERIAL port to a terminal, computer, or modem. In addition, you will

also need a:

— NULL modem adapter (customer provided) and a DB25 adapter and

cable (provided with this product) when connecting to a modem, or

— DB25 adapter (provided with this product) when connecting to a terminal

or computer for local network management. If your terminal or computer

has a 9-pin serial port, you may need a (female) DB9 to (male) DB25

adapter.

If you are connecting to . . . Use an 8-pin modular . . .

Local terminal console DB25 adapter and cable.

SNMP network management system via a

10BaseT hub connector Straight-through cable.

Modem for remote management DB25 adapter, cable, and NULL

MODEM adapter.

Installing the MCC Card

When using a . . . Install the MCC card into . . .

HotWire 8600 DSLAM chassis Slot 1 of the base chassis (i.e., the chassis set at

Stack Position #1).

HotWire 8800 DSLAM chassis Slot 19.

NOTE:

You will need to remove the filler plate before proceeding to install the MCC

card.

Do not discard filler plates. Each slot in the chassis must contain a circuit

card or a filler plate to maintain the required EMI shielding and to prevent air

leakage from the forced air cooling. Air leakage could result in overheating

which may cause the power to the circuit cards to be shut off. Store all

unused filler plates in a safe place. You may need to use the filler plates to

cover open slots in the chassis at a later time.

"Procedure

To install the MCC card:

1. Remove the filler plate from the appropriate slot.

2. Insert the MCC card into the appropriate slot:

—On a HotWire 8600 DSLAM base chassis, hold the MCC card

horizontally with component side facing up and insert it into the left and

right card guides of Slot 1. Set the Stack Position Switch to position #1.

3. Slide the MCC card into the slot. Gently, but firmly, push the card until it

properly seats in its mating connectors on the backplane.

CAUTION:

Do not force the MCC card into the slot. If it does not seat properly,

remove the card and re-install it. If it still does not seat properly, call for

service.

The MCC card performs a power-up self-test. All of the LEDs turn ON and

OFF briefly. When the self-test is completed successfully, the SYSTEM OK

LED indicator is ON (winking green).

4. Make sure the SYSTEM OK LED indicator on the MCC faceplate is ON

(green). If the LED is not ON, refer to the

Troubleshooting

chapter of the

appropriate HotWire DSLAM Installation Guide.

5. Secure the MCC card by fastening the screws on both ends of the faceplate.

6 8000-A2-GN11-10

June 1997

NOTE:

The MCC card may be replaced without disruption to user data (i.e., you can

remove and re-install the MCC card without powering down the chassis and

disrupting service to the other cards). To remove the MCC card from the

chassis, unfasten the screws on both ends of the faceplate. Then, simply

push the ejector handles outward and slide the card out.

When swapping the old MCC card with a new MCC card, it is important to

note that the HotWire DSLAM retains the Media Access Control (MAC)

address, also referred to as the physical address. This means that the new

MCC card will have the same MAC address as the old one.

Connecting to an SNMP Management System or to a

Remote Terminal via a Telnet Session

"Procedure

To connect the HotWire DSLAM chassis that contains the MCC card to an SNMP

management system or to a remote terminal via a telnet session over the

LAN-connected diagnostic network:

1. Plug the end of an 8-pin modular cable into the MANAGEMENT MCC port of

the HotWire DSLAM chassis.

2. Plug the other end of the cable into the 10BaseT hub connector to the SNMP

management system network or LAN-connected diagnostic network.

8000-A2-GN11-10 June 1997

Connecting to a Terminal or Computer for Local

Network Management

"Procedure

To connect the HotWire DSLAM chassis that contains the MCC card to a terminal

or computer:

1. Plug the 8-pin modular end of the CAT5 cable and DB25 adapter (provided

with this product) into the MANAGEMENT SERIAL port of the HotWire

DSLAM chassis.

2. Plug the other end of the cable (the DB25 interface side) into your terminal’s

(or computer’s) serial port. If your terminal or computer has a 9-pin serial

port, you may need a (female) DB9 to (male) DB25 adapter.

3. Configure your terminal or terminal emulator with the following settings:

— Baud Rate = 9600

— Data Bits = 8

— Parity = No Parity

— Stop Bits = 1

— Flow Control = XON/XOFF

— Terminal Type = vt100

Connecting to a Dial-Up Modem for Remote Network

Management

Before connecting the HotWire DSLAM chassis to a standard AT dial-up modem,

configure the modem with the following settings:

HSet the modem for auto answer. For example, ATS0=1.

HTurn off character echo. For example, ATE0.

HEnable result codes in originate mode only. For example, ATQ2.

HSet the modem to ignore Data Terminal Ready (DTR). For example, AT&D0.

"Procedure

To connect the HotWire DSLAM chassis that contains the MCC card to a

remotely connected asynchronous terminal or a remotely connected SNMP

manager via a dial-up modem:

1. Plug the 8-pin modular end of the CAT5 cable and DB25 adapter (provided

with this product) into the MGT SERIAL port of the HotWire DSLAM chassis.
