7210 SAS-D CHASSIS INSTALLATION GUIDE Installing the Chassis
Issue: 08 3HE 10087 AAAA TQZZA Edition 01 29
When a 7210 SAS-D is installed in an outside plant, such as a cell site, hut, cabinet,
or outside plant enclosure, it must be installed in an environment where, except
during installation and servicing, the compartment is sealed or properly filtered.
The product must be protected from ingress of contaminants such as outside air,
conductive pollution, volatile or corrosive elements (for example, salt-laden air),
hygroscopic dust, insects, pests, or vermin.
The humidity levels in the cabinet must be controlled to ensure a relative humidity
level between 15% and 85% (non-condensing) with short-term levels of 5% to 95%
(non-condensing). (Short-term is a period of less than 96 consecutive hours and a
total of no more than 15 days per year. This is equivalent to 360 hours per year, with
short-term periods occurring no more than 15 times per year.) The dew point
threshold in the cabinet must not be crossed.
Protection is typically achieved by deploying the product in a cabinet that is sealed
and is provided either with air-to-air heat exchangers or with air-conditioning and/or
heaters as required for the local climate. If the cabinet is the type that allows outside
air to ventilate the cabinet, it must have Hydrophobic Membrane filters, at the air inlet
and air exit, with all other parts properly sealed against outside contaminants and
moisture.
Typically, cabinets that comply with Telcordia GR-487, Generic Requirements for
Electronic Equipment Cabinets, provide this level of protection.
The ambient air temperature must be within the specifications defined in section 7.1.
For proper thermal performance, the following conditions must be met:
• For seismic applications, the rack must be a Telect Global Seismic Frame
(GS series).
• The rail mounting holes in the equipment rack must align with the mounting
holes on the chassis mounting brackets.
Required tools and hardware:
• #2 Phillips screwdriver
• Flathead screwdriver
• Anti-static bags, mats, and packaging
• ESD wrist strap
