4. Pull the rack bracket forward and insert the front rack ears on the back bracket
into holes on the front side of the front post. Push forward on the ears until the
latch snaps and locks into place. Ensure the front ears are placed into the
corresponding holes as the back ears, so that the rack bracket is level. To remove,
pull the finger tab inward with your finger and slide the ears forward.
5. Repeat steps 2 and 3 with the other chassis bracket on the opposite side of the
rack, in mirrored orientation. Ensure that the brackets are level with respect to
each other.
6. Slide the chassis and brackets onto the rack brackets from the front. Ensure the
“U” channels on the chassis bracket engage the flanges on the rack bracket.
7. Slide the chassis all the way onto the rack brackets until flush with the front of the rack.
8. Fully tighten the thumb screws with a Phillips head screwdriver.
9. Attach the AC power cord(s) packaged and supplied with the chassis and route it
to the back panel power connector(s) and then to a surge-protected power source
such as an uninterruptible power supply. Use the cable retention clamp on the
chassis to avoid inadvertently disconnecting the power.
The cabling and module installation notes from the previous section, “Standard
Chassis Mounting Hardware” on page 21, apply to this procedure.
Chassis Power Requirements
The Power & Cooling Requirements Spreadsheets on the ClearCube Support site provide
tools and detailed information about chassis power and cooling requirements. See “Power
and Cooling Requirements” on page 13 for an overview of the spreadsheets and for
instructions about downloading them.
Chassis Power Receptacles, Redundant Power, and
Power Cords
The R4300 chassis has two power receptacles that provide redundant power sources.
For redundant AC inputs and increased reliability, each power receptacle must be
connected to a separate branch power circuit. If only one power cord is connected to
the R4300 chassis, it is powered only by one circuit.
Use the AC power cord packaged and supplied with your chassis. For systems shipped
to countries that utilize a 100-130-volt power system, the included power cord is rated
at 15 amps. Systems shipped to countries with 208-240-volt power systems are
packaged with power cords rated at 10 amps.
NOTE
Older model chassis (R4200 and lower) used 10-amp-rated
power cords—these cords are NOT approved for use with
current model chassis on 100-130-volt power systems.
