Warnings and Cautions

Note Read the installation instructions in "Installing and Configuring the Management Engine 1100 Series" before you connect the system to its power source because you must be extremely careful when installing electrical devices. Failure to read and follow these guidelines could lead to an unsuccessful installation and possible damage to the system and components.

You should observe the following safety guidelines when working with any equipment that connects to electrical power or telephone wiring. They can help you avoid injuring yourself and damaging the ME1100 Series.

The following warnings and cautions are provided to help you prevent damage to the devices or injury to yourself:

Warning The safety cover is an integral part of the product. Do not operate the unit without the safety cover installed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards.

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.

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

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 This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Warning Before working on a system that has an On/Off switch, turn OFF the power and unplug the power cord.

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:

Locate the emergency power-off switch for the room in which you are working. If an electrical accident occurs, you can act quickly to turn off the system.
Disconnect all power by powering off the system and unplugging the power cord before:
- Installing or removing a chassis
- Working near power supplies
Do not work alone if potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit; always check the circuit.
Look carefully for possible hazards in your work area, such as moist floors, underground power extension cables, frayed power cords, and missing safety grounds
If an electrical accident occurs:
- Use caution: do not become a victim yourself.
- Power off the system.
- If possible, send another person to get medical aid. Otherwise, assess the victim's condition, then call for help.
- Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.
Disconnect all power and external cables before installing or removing a chassis.
Never install equipment that appears damaged.
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Always use caution when installing or modifying telephone lines.
Never perform any action that creates a potential hazard to people or makes the equipment unsafe.

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.

Always follow ESD-prevention procedures when removing and replacing components. Verify that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, making sure that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to safely ground ESD voltages. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.
Periodically check the resistance value of the antistatic strap, which should be between 1 and 10 Mohms.

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:

Bad plant wiring can result in radio frequency interference (RFI).
Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the system, and can even create an electrical hazard by conducting power surges through lines and into the system.

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:

Prevent exposure to voltages and currents inside the chassis.
Help contain electromagnetic interference (EMI) that might disrupt other equipment.
Direct the flow of cooling air through the chassis.

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.

Always follow the ESD-prevention procedures described in the section "Preventing Damage from Electrostatic Discharge" to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.
Make sure the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively within it. An open chassis allows air leaks, which could interrupt and redirect the flow of cooling air from internal components.
Electrical equipment generates hear. Ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures without adequate circulation. Make sure that the room in which you operate has adequate air circulation.

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.

Choose a site with a dry, clean, well-ventilated and air-conditioned area.
Choose a site that maintains an ambient temperature of 32 to 104 degrees F (0 to 40 degreesC).

Grounding the System

Creating a Safe Environment

Follow these guidelines to create a safe operating environment:

Keep tools and chassis components off the floor and away from foot traffic.
Clear the area of possible hazards, such as moist floors, ungrounded power extension cables, and missing safety grounds.
Keep the area around the chassis free from dust and foreign conductive material (such as metal flakes from nearby construction activity).

AC Power

The system is designed for connection to TN power systems. A TN power system is a power distribution system with one point connected directly to earth (ground). The exposed conductive parts of the installation are connected to that point by protective earth conductors.
Ensure that the plug-socket combination is accessible at all times, because it serves as the main disconnecting device.

The ME1100 Series has the following power requirements:

Universal input: 100-127/200-240 VAC
Frequency: 50-60HZ
Maximum power: 65 watts

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.

Ethernet Standards

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

An RJ-45 to RJ-45 straight-through cable to connect the ME1100 Series to a hub
An RJ-45 to RJ-45 crossover cable to connect the ME1100 Series to another device

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.

Rollover Cable

You can identify a rollover cable by comparing the two modular ends of the cable (Figure 2-1). Holding the cables in your hand, side-by-side, with the tab at the back, the wire connected to the pin on the outside of the left connector (pin 1) should be the same color as the pin on the outside of the right connector (pin 8).

Rack-Mounting the System

A rack-mount kit is included for mounting the ME1100 Series in a standard 19-inch equipment rack with two unobstructed outer posts. This kit cannot be used with other racks, such as a telco-type equipment rack, or those with obstructions (such as a power strip) that could impair access to the hard disk and power supplies. Allow sufficient clearance around the rack for system maintenance.

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Ensuring Proper Airflow

Follow these guidelines to ensure proper airflow:

Install the system in an open rack whenever possible. If installation in an enclosed rack is unavoidable, ensure that the rack has adequate ventilation.
Maintain ambient airflow to ensure normal operation. If the airflow is blocked or restricted, or if the intake air is too warm, an overtemperature condition can occur.
Allow at least 6 inches (15.24 cm) of clearance around the ventilation openings of the chassis.
Avoid placing the system in an overly congested rack or directly next to another equipment rack. Heat exhaust from other equipment can enter the inlet air vents and cause an overtemperature condition.
Equipment near the bottom of a rack might generate excessive heat that is drawn upward and into the intake ports of the equipment above. The warm air can cause an overtemperature condition in the equipment above.
Ensure that cables from other equipment do not obstruct the airflow through the chassis or impair access to the power supplies or cards. Route cables away from field-replaceable components to avoid disconnecting cables unnecessarily for equipment maintenance or upgrades.

Stabilizing the System

Follow these guidelines to stabilize the equipment rack:

Install any stabilizers that came with your equipment rack before mounting or servicing the system in the rack.
Load the rack from the bottom to the top, with the heaviest system at the bottom.
Do not stack the system on top of any other equipment. If the system falls, it can cause severe bodily injury and damage the equipment.
If you are using an equipment shelf, ensure that the shelf is constructed to support the weight and dimensions of the chassis.
If you are using a telco rack, ensure that the weight of the chassis does not make the rack unstable. Secure the telco rack with ceiling brackets if the rack is populated with heavy equipment.
Bolt the rack to the floor for stability.

Lifting the System

Follow these guidelines when lifting the system:

Disconnect all power and external cables before lifting the system.
Ensure that your footing is solid and the weight of the system is evenly distributed between your feet.
Lift the system slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the knees, not at the waist.
