• Ensure that the equipment is properly grounded.
• Do not place objects on top of unit.
CAUTION: The E1200 AC shipping containers each weigh up to 400 pounds. The unpacked chassis and
pallet weigh approximately 200 pounds. Do not attempt to lift or move the chassis without the use of a hand
cart, pallet jack, or forklift.Lift the E1200 chassis either from the bottom or by the handles provided with the
front shipping cover. Lifting by the chassis shelves or fan tray openings will cause chassis damage. Do not
remove the protective front shipping cover until the chassis is secured in the equipment rack.
Rack Mounting
When you prepare your equipment rack, make sure the rack is bolted to the floor and/or braced to a wall
or ceiling.
When you install the chassis:
• Make sure that the rack is grounded to the grounding electrode. Each DC PEM must be grounded to the
rack or building ground bus. The equipment rack must be grounded to the same grounding electrode
used by the power service in your area. The ground path must be permanent.
• Install the E1200 chassis in the rack before you install internal components or make network and power
connections.
• In an empty rack, place the chassis in the lower half of the rack to ensure rack stability.
Cabinet Placement
The cabinet must meet the following criteria:
• Minimum cabinet size is 30 inches deep and 24 inches wide.
• Minimum air flow is 750 cubic feet per minute (CFM).
• Minimum of 3 inches between the closed doors and the front of the cable management panel, and a
minimum of 3 inches between the chassis rear and the rear of the cabinet with the cabinet door closed.
With the rear doors of the cabinet open, you will need a clearance of at least 20 inches from the rear to
access the chassis fan trays.
• Minimum of 20 inches clearance at the chassis front to access the air filter, power supplies, and cards.
Power
The E1200 requires 3 AC Power Supplies in a shelf (0, 1, 2 or 3, 4, 5) or 1 DC PEM to operate. For full
redundancy, you must have 6 AC Power Supplies (so that if one power supply fails in one shelf, the
system remains operational operates with the 3 power supplies in the other shelf) or a second 2 DC Power
Entry Module (2 total)
CAUTION: You cannot power the system with both types of power supply module installed. The system must
contain only one type of power module, either AC or DC.
