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.

-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.
Refer to Pin Assignments on page 8 for pinouts.

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.

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.
