Snap-on plastic cable guides with T-shaped dividers and openings that align with each RMU space on the rack shall be attached to the front side of each rack next to the vertical cable managers to provide by-RMU cable management for cables entering/exiting the rack.
3.
A U-shaped cable management jumper tray shall be attached to the top of each rack to provide a side-to-side/rack-to-rack pathway for cables. The trough shall be 6” (150 mm) wide and 5.2” (132 mm) deep; shall align with the front-facing vertical cable mangers and shall have a formed radius to support cables where cables enter/exit the trough. Omit Item 3 if ladder rack will be attached directly to the top of the rack.
4.
Finish shall be epoxy-polyester hybrid powder coat in the color as specified below. Plastic edge protectors, spin-open latches and snap-on cable guides are black.

Attach a single-gang electrical outlet box to the base of each rack to provide a location for an electrical power connection for equipment on the rack. Refer to the electrical plan for wiring requirements.
2.
Each rack shall have a minimum of one vertical power strip attached to the side of the rack or the rear of the vertical cable manager to distribute power to equipment. The installer shall provide mounting hardware to attach the power strip to the keyhole slots on the rack or vertical cable manager.
3.
Power strips shall be single-phase, single-inlet, 20-outlet vertical power strips rated for 125/250 VAC and 16 A. The power strips shall have a built-in current meter with digital display, one IEC-320 C-20 power inlet and (20) IEC-320 C-13 power outlets, no circuit breakers and no surge protection.

PART 3 – EXECUTION 3.1
INSTALLATION A. Free Standing Relay Racks 1.
Verify that equipment mounting rails are sized properly for rack-mount equipment before attaching the rack to the floor.
2.
All racks must be attached to the floor in four places using appropriate seismic-rated floor mounting anchors and additional bracing as required by building codes and the recommendations of a licensed structural engineer.
271116-5
Communications Racks
Note: Seismic installations require additional bracing of racks, cabinets and overhead cable runways to building structure as advised by and certified by a licensed structural engineer. 3.
Racks shall be grounded to the TGB using appropriate hardware provided by the contractor. The ground will meet local code requirements and will be approved by the Authority Having Jurisdiction (AHJ).
4.
Ladder rack may be attached to the top of the rack to deliver cables to the rack. The rack shall not be drilled to attach ladder rack. Use appropriate hardware from the ladder rack manufacturer.
5.
The equipment load shall be evenly distributed and uniform on the rack. Place large and heavy equipment towards the bottom of the rack. Secure all equipment to the rack with equipment mounting screws.
