Introduction to the FR42612L Cabinet
This section describes the functions, appearances, physical structures, ESD jacks, and technical specifications of FR42612L cabinets.
Functions
FR42612L cabinets conform to the IEC 60297-1 and are assembled cabinets for ease of expansion. The distance between front and rear mounting bars in the cabinets can be adjusted at a minimum step of 25 mm. An FR42612L cabinet has the following functions:
- Delivers space for accommodating and interconnecting components.
- Is equipped with castors to facilitate movement on a flat floor or on an incline less than or equal to 10 degrees.
- Protects components from pollution.
- Protects components from damage.
Appearance
The exterior of an FR42612L cabinet is in sand-textured black. Figure A-1 shows an FR42612L cabinet.
Physical Structure
An FR42612L cabinet consists of the rack, front door, rear door, side panels, top cover, and mounting bars, as shown in Figure A-2.

Power supply and power distribution |
An FR42612L cabinet supports two types of power distribution units (PDUs): single-phase 220 V 32 A PDU and three-phase 380 V 32 A PDU. Each cabinet must be equipped with two PDUs of the same type.
NOTE:
If single-phase power inputs are used, the total power consumption of all devices in a cabinet cannot exceed 6336 W.
|
- The operating temperature and relative humidity are measured 1.5 m above the ground and 0.4 m in front of the cabinet.
- The short term is defined as no more than 48 consecutive hours and 15 accumulative days per year.
