ASSEMBLY
1. Install top width cross brace and bottom horizontal foot
A. Lay upright channels on rack mount face with open sides of the channel facing each other.
B. Locate thru holes at the top of the channel and align with top width cross brace holes on
inside of channel. (For 19" mounting, use outer set of holes; for 23" mounting, use inner set
of holes). Install with (2) 3/8" hex head bolts, FINGER TIGHTEN.
C. Locate thru holes at the bottom of the channel; for toe out conguration mount bottom
horizontal foot on outside of channel, for toe in conguration mount on inside. Install (2) 3/8”
hex head bolts, (4) 3/8” external tooth lock washers into (1) 3/8” nut plate on each channel.
FINGER TIGHTEN.
2. Stand rack upright. Repeat steps 1.B. & 1.C. for the opposite side of rack.
3. Determine the orientation of center waterfall brackets :
A. Orient center waterfall bracket with radius toward outside of rack when : cables run on the
inside of channel and exit the top of the rack without Ladder Rack Brackets (4PLRBV48)
B. Orient center waterfall bracket with radius toward center of rack when : cables and bundles
run outside of the channel or when using Ladder Rack Brackets (4PLRBV48)
4. Install center waterfall bracket on inside of rack fastened with (1) #12-24 screw through both front
and rear horizontal slots on top cross brace. Install second center waterfall bracket in the same way.
5. Final tightening
Rack is self-squaring: Ensure pins in horizontal top and bottom members align with thru hole slots in
vertical uprights. Tighten all bolts using a 9/16” socket or wrench (24 ft-lb torque is recommended).
6. Slide center waterfall brackets to desired locations and tighten with screwdriver.
7. Install front and rear top waterfall trough with ¼-20 Carriage bolts and 7/16” socket or wrench.
Round dome should be on top.
8. Installing CM-23 & CM-24 1/4 turn “D” Rings
A. Racks come with (2) kits of (10) CM-24 1/4 turn “D” rings. On each 1/4 turn “D” ring there are
(2) square protrusions. Insert either square (depending on your desired orientation) into the
any 3/8" square receiving hole on the rack and turn the 1/4 turn “D” ring 45° to lock into
place. This rack also accepts Optional CM-23 1.5" x 3.5" 1/4 turn “D” rings and install in
the same fashion.
B. Slide center waterfall brackets to desired locations and tighten with screwdriver.
9. Racks come with (2) kits of (10) CM-24 1/4 turn “D” rings. On each 1/4 turn “D” ring there are (2)
square protrusions. Insert either square (depending on your desired orientation) into the any 3/8"
square receiving hole on the rack and turn the 1/4 turn “D” ring 45° to lock into place. This rack also
accepts Optional CM-23 1.5" x 3.5" 1/4 turn “D” rings and install in the same fashion.
10. When mounting to a cement oor, recommended mounting hardware is Great Lakes Seismic

POWER AND GROUNDING OF ALL RACKS
When using PDUs, each PDU should be connected to a committed branch circuit that is rated
for the continuous load of all the equipment connected. When not using a PDU, each piece of
equipment should be connected to a dedicated branch circuit.
PROTECTIVE EARTHING/GROUNDING
A main protective earthing stud is provided.
WARNING:
To avoid injury to persons or loss of life, ground rack individually to the dedicated branch circuit
earthing ground.
CONNECTING MAIN PROTECTIVE EARTHING STUD TO THE DEDICATED BRANCH CIRCUIT
EARTHING GROUND CONDUCTOR
Connect the dedicated branch circuit earthing ground conductor to the main protective earthing
stud located on the support frame using a listed ring or closed-loop terminal.
PARTS NOT BONDED TO PROTECTIVE EARTHING TERMINAL
The following parts are not eectively bonded to the protective earthing terminal: Center Waterfall
Bracket on the CMR Racks. If these parts need to be bonded to the protective earthing terminal, do
so in accordance with Article 250 of the National Electric Code.
Although equipment may physically t into a Great Lakes rack, with or without brackets,
customers must also review and comply with the equipment manufacturer’s installation and other
requirements. For more information, please contact your Great Lakes representative or call
1-866-879-4522.
When any equipment or accessory is installed in a Great Lakes product, the installation procedures,
recommendations and product warranty requirements of the equipment manufacturer must be
followed. Great Lakes will not be responsible for any losses or claims arising from a customer’s
installation of electrical, electronic or other third party products in any Great Lakes racks, unless
caused solely by a written conguration prepared by Great Lakes for that customer or by a
conguration provided by Great Lakes’ website, any conguration relies on complete and accurate
information from the customer.
Product specications are subject to change without prior notice.

SAFETY CONSIDERATIONS
WARNING: Improper handling and use of the racks could result in equipment damage, serious
injury, or possible death.
Only trained service personnel should be used to remove the enclosure from the pallet. Also, be
sure you have a sucient number of service personnel. Do not attempt to move enclosures by
yourself.
LOADING EQUIPMENT
WARNING: Only install equipment after the CMR/CMRX Racks have been properly secured. Do not
move the rack assembly while loaded. To maintain a uniform distribution of the mechanical load in
the rack, load the heaviest equipment rst, at the bottom of the rack and load the lighter units at the
top.
Only UL® Listed ITE (Information Technology Equipment) units should be installed inside the rack.
Be sure to read and follow all individual manufacturer equipment manuals for safety and installation
instructions.
Proper spacing is required when installing electrical equipment to avoid electrical shock. Maintain
minimum spacing between the accessories and components and the computer enclosure assembly
for safe operation of the equipment when installed in accordance with the National Electric Code
ANSI/NFPA 70-1999.
The ambient temperature operating range for the racks and accessories is +50 to +95° F (+10 to
+35° C). The non-operating temperature is -4 to +140° F (-20 to +60° C).
