Warning Read the installation instructions before you connect the system to its power source.


Warning The device is designed to work with TN power systems.


Warning The ports labeled "10BaseT", "100BaseTX", and "10/100" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Avoid connecting these circuits to telephone network voltage (TNV) circuits.


Warning There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.

Working with Electricity

Follow these guidelines when working on electrical equipment:

Preventing Damage from Electrostatic Discharge

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs when electronic components are handled improperly and can result in complete or intermittent failures.

Preventing EMI

When you run wires for any significant distance in an electromagnetic field, electromagnetic interference (EMI) can occur between the field and the signals on the wires.

Note that:

To predict and remedy strong EMI, consult RFI experts.

Covering Empty Slots

Ensure that all cards, faceplates, and covers are in place. Blank faceplates and cover panels are used to:

Preparing Your Site for Installation

Make sure your site is prepared properly before beginning installation.

Environmental

When planning your site layout and equipment locations, keep in mind the precautions described in this section to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or unusually high errors with your existing equipment, these precautions will help you isolate the cause of failures and prevent future problems.

Use the following precautions when planning the operating environment for your ME1100 Series.

Choosing a Site For Installation


Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.

Grounding the System


Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

Creating a Safe Environment

Follow these guidelines to create a safe operating environment:

AC Power

The ME1100 Series has the following power requirements:


Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Make sure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. and 240 VAC, 10A international are used on the phase conductors (all current-carrying conductors).


Warning The device is designed to work with TN power systems.

Cabling

Use the cables in the accessory kit to connect the ME1100 Series console port to a console or computer that is running a console program. In addition to the console cable, you must supply your own standard Ethernet cable to connect the ME1100 Series to your network. This section details the pinout information for these cables, so that you can purchase the correct cable for your network connection, and replace the console cable and adapters if that becomes necessary.

A structured wiring system provides a standardized way to wire a building for all types of networks for the ME1100 Series appliance to be installed. The main distribution frame links all the building's interior wiring and provides an interface connection to circuits coming from outside sources such as the local telephone company. Wiring hubs (peripherals for cabling installations) provide the connection logic unique to Fast Ethernet cables that the ME1100 Series uses. Unshielded twisted pair (UTP) copper wire is used to connect the ME1100 Series and distributes the network connections to wall jacks near each piece of network equipment.


Warning The ports labeled "10BaseT", "100BaseTX", and "10/100" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Avoid connecting these circuits to telephone network voltage (TNV) circuits.

Ethernet Standards

To connect the ME1100 Series to your network, you must use one of the following Fast Ethernet cables:

The Ethernet configuration using unshielded twisted pair (UTP) wire is known as 10BaseT because it uses 10 megabit per second (Mbps) signaling speed, direct current, or baseband, signaling, and twisted pair wire.This configuration includes a central wiring hub with special circuitry to isolate malfunctioning segments of the network. UTP wire uses an RJ-45 connector at each end of the wire. New signaling schemes such as 100BaseT and gigabit Ethernet use the same UTP cabling with upgraded hubs and adapters.

Use a CAT 5 UTP cable at minimum to connect to a 100BaseT network. Use a CAT 3 UTP cable at minimum to connect to a 10BaseT network.

Table 2-1 shows the pinouts for a straight-through 100BaseT cable.

Console Cable and Adapter

The EIA/TIA-232 console port on the ME1100 Series is configured as data terminal equipment (DTE) and uses a DB-9 connector. A console cable kit is provided with your ME1100 Series to connect an ASCII terminal or a PC running terminal emulation software to the console port. The kit contains an RJ-45 to RJ-45 rollover cable and two RJ-45 to DB-9 female DTE adapters.

You can attach the two RJ-45 to DB-9 adapters to the RJ-45 to RJ-45 rollover to create a DB-9 to DB-9 null-modem cable.

Table 2-3 shows the pinouts for this configuration.
