1. Place the ESD mat on the floor where you will be working and put on the ESD strap. Make
sure the ESD strap is touching your skin and that the other end is connected to a verified
ground.
2. Choose which side of the switch you want even with the rack vertical support. Either the side
with the power supply units or the side with the IB connectors can be even with one of the
vertical rack supports. Short switches have the OPN character -B and are 1.716" (1U) H x
17.17" W x16.84" D 43.6mm X 436.2mm X 427.7mm. Standard switches have the OPN
character -S and are 1.716" (1U) H x 17.17" W x24.71" D 43.6mm X 436.2mm X 627.7 mm.
Things to consider before choosing where to mount the rails and rail slides.
• Air flow
• Configuration of already installed equipment
• Cable bending radius
The distance between the rack and the door can be as little as 4 cm on one side of the rack and as
much as 18 cm on the other side of the rack. Keep in mind that there can be as many as 36 cables con-
nected to the switch.
• Do you want the connector side recessed in the rack to allow for a larger cable bending
radius?
• Will the connector side be recessed past other equipment in the rack and will this be prob-
lematic?
