Safety precautions and general hazards

The following general safety precautions must be observed during all phases of operation, service and repair of this equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture and intended use of the equipment. Codian assumes no liability for the customer's failure to comply with these requirements.

If the MSE 8000 is installed in a closed or multi-unit rack assembly, the ambient temperature may be greater than the room ambient temperature, therefore consideration should be given to installing the MSE 8000 in an environment compatible with the maximum rated ambient temperature specified in the Operating Environment section of this information.

The installation of the MSE 8000 in a rack should be such that the amount of air flow required for safe operation is not compromised.

Mounting of the MSE 8000 in a rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.

The MSE 8000 must be installed in a restricted location as defined by EN, IEC and UL60950. This is defined as an area intended for qualified or trained personnel only with access controlled by a locking mechanism such as a key.

The MSE 8000 when fully loaded with blades can exceed 100kg (220 pounds) in weight. The MSE 8000 weighs approximately 50kg (110 pounds) when empty of blades and fan trays. Two people using an appropriate lifting device are required to install the MSE 8000 system or remove it from a rack safely.

All operations for the installation can only be performed within a restricted location by trained service personal. The MSE 8000 has no user installed parts.

The MSE 8000 must be placed in the lowest available place within a rack to provide stability. If the rack provides stabilizers they must be used during installation.

The MSE 8000 uses front-to-rear cooling fans. To ensure adequate cooling, allow a minimum of 91.4cm (36 inches) in front and at the rear of the MSE 8000 system. Allow the same distance for installation and servicing. Do not block the fan intake or outlet. Ensure that the fan intake is not placed inline with the outlet from any other fan or convection cooled device.

Ensure that the rack has been installed in the building in accordance with the manufacturer's instructions and that it is strong enough to accommodate the weight of the MSE 8000 and any other units placed within it.

Before un-installing the unit from the rack, all blades must be removed from the chassis and all power connections must be removed from the MSE 8000.

You must install either a blade or a blanking blade in each of the ten slots in the chassis.

Each power cable is required to have its own circuit breaker.

All circuit breakers must be in the OFF position before installing or removing the power connections.

For power redundancy, each power feed should be powered from a separate power source.

Only specified hot swap operations are allowed with the power connected. For all other actions, you must either disconnect the power or have the circuit breakers in the off position. All circuit breakers must be OFF to remove power from the MSE 8000.

Warning! Hazardous moving parts. Keep fingers and other body parts away.

The MSE 8000 is capable of accepting -40.5V DC to -72V DC in abnormal conditions. It is highly recommended that only -48V DC to -60V DC is used.

Any DC power cable supplied with an AC power supply unit for the MSE 8000 is considered an internal cable to the MSE 8000 system.

The MSE 8000 powering scheme does not require a reference to earth from the negative or return lines. The conditions for powering the MSE 8000 are such that the negative terminal must have a more negative voltage than the return terminal, and that power inputs A and B must each provide identical powering schemes.

Fuses on the system blades and fan trays are not operator or service personnel replaceable parts.

Servicing the MSE 8000

Fuse identification is by the following markings on the system blades and fan trays. All MSE 8000 fuses are of identical type, Rated voltage 250 VAC, Rated Current 6.3A, Breaking Capacity 1500 A, Characteristic Quick Acting.

Blade fuses in negative and return lines in both Sources A and B indicated by J7, J8, J9 and J10 located on the power boards on each of the blades.

Fan tray fuses in negative and return lines in both Sources A and B indicated by J9, J10, J11 and J12 located on the power boards on each of the fan trays.

Note that the MSE 8000 fuses are not customer or service personnel replaceable parts.

The safety precautions listed below represent warnings of certain dangers of which Codian is aware. You, as the user of the product, should note these warnings and all other safety precautions necessary for the safe operation of the equipment in your operating environment.

Do not service or adjust alone

Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present.

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

Do not operate the unit with the cover removed. Operating the unit without the cover in place will invalidate the safety approvals and pose a risk of fire and electrical hazards.

Do not work on the DC power lines while the system is connected to power.

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

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

• The console, Ethernet and ISDN ports on the ISDN module are SELV interfaces. ISDN lines where they enter the building are usually classified as TNV. These lines should never be connected directly to the ISDN module. Use an isolating device such as a Network Termination Unit (NTU) or Channel Service Unit (CSU) between off-premise ISDN lines and the ports on the ISDN module

This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.

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
