or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST
NOT be metallically connected to interfaces which connect to the OSP or its wiring. These interfaces
are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in
GR-1089-CORE, Issue 5) and require isolation from the exposed OSP cabling. The addition of Primary
Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.
You can use the grounding lug to attach a wrist strap for ESD protection during servicing.
To prevent the system from overheating, do not operate it in an area that exceeds the maximum

Installation Guidelines

Before installing the switch, verify that these guidelines are met:
•
•
•
•
•
•
•
•
If the switch is installed in a closed or multi-rack assembly, the temperature around it might be greater than
Note
normal room temperature.

For Ethernet ports and 1000BASE-T SFP module ports, cable lengths from the switch to connected
devices can be up to 328 feet (100 meters).
For cable requirements for 1000BASE-T SFP module connections, see the "Cable Pin-outs" section on
figure B-7.
Operating environment is within the ranges listed in
Front-panel indicators can be easily read, and access to ports is sufficient for unrestricted cabling
AC power cord reaches from the power outlet to the connector.
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
Airflow around the switch and through the vents is unrestricted.
For an outside plant installation (cell site cabinet, hut etc.), it is required that the ME 1200 switch be
protected against airborne contaminants, dust, moisture, insects, pests, corrosive gases, polluted air or
other reactive elements present in the outside air. To achieve this level of protection, we recommend that
the unit be installed in a fully sealed enclosure or cabinet. Examples of such cabinets include IP65
cabinets with heat exchanger complying with Telecordia GR487. Temperature must be maintained
within –40ºC to 65ºC.
Before you connect the switch to a power source, note the power consumption specifications in
