Introduction to an FR42612L Cabinet
This section describes the function, exterior, physical structure, ESD jack, and technical specifications of an FR42612L cabinet.
Function
The FR42612L cabinet complies with IEC 60297-1 and is an assembled cabinet for ease of expansion. The distance between front and rear mounting bars in the cabinet can be adjusted at a minimum unit of 25 mm. The cabinet has the following functions:
- Delivers space for accommodating components that can be interconnected.
- Provides castors to facilitate movement on a flat floor or a gradient that slopes to less than or equal to 10 degrees.
- Protects components from dust.
- Prevents components from being damaged.
Appearance
The exterior of an FR42612L cabinet is in sand texture black. Figure 7-1 shows the appearance of an FR42612L cabinet.
Physical Structure
The FR42612L cabinet consists of the racks, front door, rear door, side panels, cover, and mounting bars. Figure 7-2 shows the structure of an FR42612L cabinet.

Power supply and power distribution |
An FR42612L cabinet supports two types of PDUs, namely, 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:
In single-phase power supply mode, the maximum power consumption of all devices in a cabinet cannot exceed 6336 W.
|
- Operating temperature and humidity are measured 1.5 m above the floor and 0.4 m in front of the device in the equipment room.
- Short-term operation means that the consecutive operating time does not exceed 48 hours, and the annual accumulative operating time does not exceed 15 days.
