Page 15: Ventilation And Heat Dissipation
Through convection, the heated air rises to the exhaust. By either simple convection, or a combination with an optional extractor fan, the heated air exhausts though the vented top cap, illustrated in Figure 6. Keysight Instrument Rack E7950A-1.3m E3661B-1.6m E3662B-2.0... -
Page 16: Cable Access
Standard Racks The following parts are included with every Keysight instrument rack. The top of the rack incorporates a ventilation path through the roof of the rack and the convection current heat exit for the heat generated by the installed equipment. -

Figure 7 Vertical Mounting Columns Each product or device installed requires one or more EIA unit increments. One standard EIA rack mount increment is equal to 44.45 mm (1.75 in). Keysight Instrument Rack E7950A-1.3m E3661B-1.6m E3662B-2.0... -
Page 18: Support Rails
The rails are screwed to the vertical columns. See Figure 7 for an illustration of a System II rail. System II rails are used with any instrument that conforms to Keysight System II product specifications, and are the standard support rail. Only after securing a pair of rails with screws can equipment be installed. -
Page 19: Anti-Tip Stabilizer
Anti-tip Stabilizer Standard on each Keysight rack is a retractable anti-tip stabilizer mechanism. Located at the bottom center of the rack, it provides temporary additional stability when installing or removing equipment components. The anti-tip stabilizer should also be used when slide-mounted components are in their extended position. -
Page 20: Filler Panels
The anti-tip assembly is not a substitute for ballast. Monitor Mount Kit An optional monitor mounting kit is available. Support Rails Two optional support rail types are available. VXI Rail VXI rails are used with Keysight VXI mainframe equipment. Keysight Instrument Rack E7950A-1.3m E3661B-1.6m E3662B-2.0... -
Page 21: Non-Keysight Rail
Non-Keysight Rail Non-Keysight rails are used with any non-Keysight products that mount at the bottom of the EIA envelope. The Non-Keysight rails extend lower into the EIA envelope than the standard and the VXI rails. Keysight Instrument Rack E7950A-1.3m E3661B-1.6m E3662B-2.0... -
Page 22: Set Up
Floor Space and Loading Observe floor loading requirements (especially raised floors) and ensure adequate space before moving your Keysight rack, and all safety items while moving. At maximum gross weight, the floor must be able to support 677-kg/ sq cm (2000 lb./sq in). -
Page 23: Cooling
Components generating the most heat should be placed closest to the top to avoid heating the equipment above it as the generated heat rises in the convection current. Figure 10 shows projected temperature with and without the extractor fan. Keysight Instrument Rack E7950A-1.3m E3661B-1.6m E3662B-2.0... -
Page 24: Weight And Balance
When a trained service personnel serviceable only product is extended, the use of the rack stabilizer assembly is required, but counterweight ballast is not. See Figure Keysight Instrument Rack E7950A-1.3m E3661B-1.6m E3662B-2.0... -
Page 25: Work Surface/Keyboard
To reduce the risk of rack instability when using a work surface as illustrated in Figure 12, use the following worksheet to determine the need for additional counterweight ballast. If there are no work surfaces or keyboard mounting kits in the rack, this worksheet can be ignored.

Evaluate the left side of the equation. 100,000 + 3,162,277.66 = 10 x/10 3,262,277.6 = 10 x/10 Take the log of both sides of the equation (return to dB units). log (3,262,277.66) dB = x/10 dB Keysight Instrument Rack E7950A-1.3m E3661B-1.6m E3662B-2.0... -
Page 28: Estimating Total Noise
For example, the combination of a 50 dB noise and a 54 dB noise has a difference of 4 dB. Using Figure 13, 4 dB difference results in adding 1.4 dB to the higher noise, resulting in an estimated 55.4 dB total noise. Keysight Instrument Rack E7950A-1.3m E3661B-1.6m E3662B-2.0... -
