Unpacking and Installing the SilkWorm 12000 in the
Rack
This section provides instructions for unpacking the SilkWorm 12000, site planning, installing the switch
in an EIA rack, and tips on cable management.
The SilkWorm 12000 Rack Mount Kit is designed for use in a standard 19 inch EIA rack that has rack
rails with the "square" type of holes.

Unpacking the Switch

Due to the weight and size of the SilkWorm 12000, it is important to plan where to unpack it and how to
transport it. For example, it might be easier to unpack it in the shipping room and use a cart or mobile
hydraulic lift to bring it to the rack, or to transport to the rack while it is still in the packing crate, using a
pallet jack, and then unpack it. The crate on a pallet jack will fit through doorways wider than 36 inches.
To minimize the amount of vibration during transportation, bring the packing crate as close as possible to
the final destination before unpacking the switch.
To unpack the switch and prepare it for installation:
1. Remove the outer shell or shipping case.
2. Remove the static bag.
3. Unscrew the shipping screws from the pallet.
4. Remove the front door and cable management tray to prevent breakage while the switch is installed
in the rack, and set aside.

Site Planning

The SilkWorm 12000 requires two dedicated branch circuits, each protected by a circuit breaker in
accordance with local electrical codes, and terminated with a receptacle appropriate to the power cord.
Only use power outlets that were installed by a licensed electrician. Verify that the supply circuit, line
fusing, and wire size are adequate according to the electrical rating on the switch nameplate. The voltage
required is 200 to 240 VAC (in the USA the available voltage is usually 208 or 240 VAC, the receptacles
are usually NEMA L6-20R, and the branch circuit breakers are usually rated at 20 amps each).
•
Placing the switch on the floor is not recommended because this would prevent using the cable
management tray and would make cable routing unnecessarily difficult.
•
To ensure adequate cooling, install the switch with the port side of the switch facing the aisle into
which exhaust air is released (usually the "service" aisle). This prevents the switch fans from pulling
in heated exhaust air, since the air enters through the vents in the back of the chassis and exits from
the vent in the top of the front of the chassis.
•
The air intake and exhaust vents require a minimum of two inches of airspace.
