4. Locate three people to assist in moving the 5U enclosure in its plastic bag onto the mechanical lift, using an appropriate
safe lifting technique to perform the following actions:
a. Position one person at the front to grip the front belt strap securely by both loops, not by any portion of the front or
rear panel areas.
b. Position one person at each rear corner to grip both rear belt straps by the loops on that side.
c. Simultaneously lift the 5U enclosure, using appropriate safe lifting technique while moving it to a static-protected
location, and then to the mechanical lift for mounting to the rack cabinet.
5. Slide off the plastic bag to access the chassis while making sure the chassis is centered on the lift.
6. Complete the following actions to prepare the 5U enclosure chassis for installation:
a. Facing the front of the chassis, grasp the right rack flange cover, gently work the cover free, and set it aside in a safe
location.
b. Grasp the left rack flange cover, gently work the cover free, and set it aside in a safe location.
Install the 5U rackmount rail kit
The 5U enclosure requires rackmount hardware for installation into a standard 1.0m or 1.2m rack and occupies 5 EIA units of
rack space (22.22cm or 8.75 inches) per unit. The rail kit contains a left and right rail designed and tested to handle the 5U
enclosure and provide for installation of multiple enclosures without loss of rack space. Product function and user safety hinge
on their proper installation. The following task assumes your rack posts have square mounting holes.
You must take all appropriate rack cabinet safety precautions before mounting the 5U enclosure into a rack.
CAUTION Observe all the following directives:
Always place the rack cabinet on a flat, leveled surface. Do not install an expansion enclosure into a rack cabinet until you
l
verify the rack cabinet is level.
Follow prescribed leveling procedures from the rack cabinet manufacturer.
l
Never install or remove from the rack cabinet more than one expansion enclosure at a time. This helps prevent the rack
l
cabinet from tipping or falling.
Verify the rack cabinet meets all safety requirements when configured with expansion enclosures.
l
Verify connections comply with all electrical requirements.
l
Verify the system complies with all temperature and exhaust requirements.
l
To adhere to safety precautions when mounting the 5U enclosure into a rack cabinet:
1. Read and observe all warning and caution labels on the 5U enclosure.
2. Verify the rack cabinet is on a flat, leveled surface because any incline or unevenness stresses the rack cabinet and the 5U
enclosure. A 5U enclosure in an uneven rack cabinet resists smooth movement on the rails and possibly distorts the 5U
enclosure.
3. Verify the rack cabinet design supports the total weight of 5U enclosures and has stabilizing features to prevent the rack
cabinet from tipping or being pushed over during installation or normal use.
4. Do not lift the 5U enclosure without a mechanical lift. No single person should ever lift a 5U enclosure without assistance.
5. Mount 5U enclosures into the rack cabinet from the bottom to the top during installation.
