Service port surge protection

Common mode: ±6 kV

Power supply surge protection

Using 580 W AC or 1000 W AC power modules: ±6 kV in differential mode, ±6 kV in common mode

Using 650 W DC power modules: ±2 kV in differential mode, ±4 kV in common mode

Dimensions (H x W x D)

Basic dimensions (excluding the parts protruding from the body): 44.4 mm x 442.0 mm x 425.0 mm (1.75 in. x 17.4 in. x 16.73 in.)

Maximum dimensions (the depth is the distance from ports on the front panel to the handle on the rear panel): 44.4 mm x 442.0 mm x 451.3 mm (1.75 in. x 17.4 in. x 17.77 in.)

When 1150 W power modules are installed, they stretch out from the chassis. Therefore, the total depth of the switch changes to 541.1 mm (21.3 in.).
