1.4 Hardware Components
ES4710BD consists of the chassis, power supply system, ventilation system, system board, etc.
1.4.1 Chassis
The ES4710BD uses a 19-inch Rack Mountable Chassis, with the standard dimensions of 436mm(W)
x 797(H) x 478mm(D).
The chassis consists of functional block, thermal block, and power supply
block. The function module block is a board rack, which is the supporting structure for ES4710BD
system boards (10 boards max). Ten wiring clips are provided in the upper and lower parts of the
board rack respectively, for the positioning of all kinds of cables. In addition, there are two ESD
Wrist Strap Connectors on the board rack, located on the left side of the upper and lower rack
respectively. The thermal block is located on the upper part of the board rack, allowing three fan
trays (2 axial fans for each fan tray). Dust gauze is provided under the board rack for filtering air
circulation through the rack. The power block under the dust gauze provides power to the system,
supporting up to three power modules. The power modules insert into the power slots from the front,
with the distribution box at the back of the rack for maintenance. Closely beside the distribution box,
