Power Up

The AC version of the MX2800 STS-1is provided with asix-footpower cord, terminated by athree-prongplug which connects to a grounded 120 VAC power receptacle.

Power to the AC version of the MX2800 STS-1must be provided from a grounded 120 VAC, 60 Hz receptacle.

The DC version of the MX2800 STS-1is provided with two4-positionmodular terminal lug connectors. These connectors make it easier to perform initial wiring and to connect and disconnect DC power when replacing rackmount units.

For more detailed information on power connections, refer to

Chapter 2. Installation and Operation

The following UL requirements must be met during installation of the MX2800 STS-1DC version:

1.Disconnect all power sources prior to servicing (unit may use multiple power sources).

2.Input: Minimum 48 VDC, 0.8 A

Minimum 120 VAC, 0.32 A

3.Connect to a reliably grounded -48VDC source which is electrically isolated from the AC source.

4.The branch circuit overcurrent protection shall be a fuse or circuit breaker rated minimum 48 VDC, maximum 20 A.

5.A readily accessible disconnect device that is suitably approved and rated, shall be incorporated in the field wiring.

6.The chassis should be connected to an earth ground using the ground stud located between the AC and DC power sources on the rear panel.

7.The unit shall be installed in accordance with the requirements of NEC NFPA 70.

8.The unit shall be installed in accordance with Articles 400 and 364.8 of the National Electrical Code NFPA 70 when installed outside of a Restricted Access Location (i.e. Central Office, behind a locked door, or service personnel area only).

9.Care should be taken not to upset the stability of the equipment rack after installation is complete.

To meet the UL requirements during installation, use copper conductors only.

RACKMOUNT INSTALLATION

The MX2800 STS-1can be mounted into a standard19-inchor23-inchequipment rack. Follow these steps to mount your unit into a rack:

1.Prepare the MX2800 STS-1mounting ears by scraping the paint away from the mounting ears’ portion that makes contact with the rack and the portion where the screw mounts into the side of the MX2800STS-1.

2.Install the mounting flanges on each side of the MX2800 STS-1at one of the three available positions.

Be sure to install the flanges with the screws provided.

3.After the flanges have been installed, position the MX2800 STS-1at the correct location within the rack and secure the mounting flanges to the mounting rails of the rack.

4.Make all network, DTE, and power connections to the rear of the unit. See Power Up on page 2-2 for more information on making the DC power connection.

5.Using the 8-positionmodular toDB-9female connector and the8-positionmodular to8-positionmodular cable, connect a

VT 100 terminal device to the CRAFT port on the front panel of the unit.

Two MX2800 STS-1smay be stacked with no spacing between units. ADTRAN recommends 1U (1.75") of separation above and below the two stacked units. This spacing allows the unit to dissipate heat. The design of the MX2800STS-1uses the chassis to distribute heat generated by the unit's internal cards. This design allows the unit to operate without a cooling fan, which increases its overall reliability.

Connecting the Breakout Panel

The optional breakout panel (P/N 1200291L1) connects to the MX2800 STS-1via theIN andOUT Champ connectors located on the back of the unit, and provides 28 RJ connectors for the individual T1s/E1s. Shipment includes twosix-foot,64-pinto64-pinAmp cables which allow direct cabling to the

MX2800 STS-1.Connect the breakout panel’sIN Champ connector to the MX2800STS-1’sIN Champ connector and the breakout panel’sOUT Champ connector to the MX2800STS-1’sOUT Champ connector (seeFigure 2-2).

Chapter 2. Installation and Operation

LAN Port

The LAN port is an8-pinmodular connector that provides a 10BaseT ethernet LAN interface. ThisLAN interface is used for SNMP and Telnet control.

Connect the LAN port to intra-buildingwiring only.

Modem Port

The MODEM port is an8-pinmodular jack that provides a telephone line (POTS) connection for the internal V.34 modem.

The MX2800 STS-1can be configured as adial-inhost and also as adial-out-on-Trapdevice (meaning the unit dials out to a specified host to report error conditions).

Information regarding the built-inmodem applies to the following list of numbers: 4200659L1, L2, L3, and L4.

Noncritical and Critical Alarm Connectors

The alarm connectors connect to the three contacts of a Form C type relay on the main board of the MX2800 STS-1.This relay is activated any time the MX2800STS-1detects an alarm condition on theSTS-1network interface. BothNC (normally closed) andNO (normally open) contacts are provided.

Connect alarms to one of the three-positionmodular terminal lug connectors (provided). These connectors make it easier to perform initial wiring and to connect and disconnect alarms when replacing

rackmount units. Once a modular connector is wired, push it firmly into the rear panel NONCRITICAL orCRITICAL connector.

The alarm functions can be enabled or disabled through the ALARM RELAYS section of theCONFIGURATION menu (see the sectionAlarm Relays on page 3-18).

Network Interfaces

The network interfaces are full-duplexcircuits provided by four BNC coaxial cable connections (two for each controller card). The receive data from the network is connected to the RX (IN) connectors, while the transmit data from the MX2800STS-1is connected to the TX (OUT) connectors.

Network interfaces must be connected using coaxial cables that have the shields grounded at both ends.

DSX-1/E1Interfaces

The DSX-1/E1interfaces are64-pinAmp connectors. These interfaces provide Tx and Rx connections between the unit and equipment such aswire-wrappatch panels,punch-downpanels, or breakout panels.

Connect the DSX-1/E1interfaces tointra-buildingwiring only.

Power Connection

The DC and AC power connections are described earlier in this chapter on page 2-2.

The CRAFT port, an8-pinmodular jack, provides connection to aVT-100EIA-232compatible interface using the supplied8-pinmodular toDB-9female connector and the8-pinto8-pinmodular cable.

Establishing Terminal Connection

To connect the MX2800 STS-1to aVT-100terminal, follow the steps below:

1.Configure the VT-100terminal for 9600, 19200, 38400, or 57600 baud,8-bitcharacters, no parity, and one stop bit (xxxx, 8N1).

2.Using the terminal interface cable adapter provided by ADTRAN, connect the DTE port of a terminal to the 8-pinmodular jack labeledCRAFT on the MX2800STS-1front panel.

3.Initialize the terminal session.

4.Press Enter repeatedly until the password prompt appears.

5.Enter the password. The factory default password is adtran (alllower-case).TheMAIN MENU appears (seeFigure 2-5 on page 2-11).
