Mounting rails are optional for this system. Be sure you have received the correct rail kit for
your server.

the full weight of the rack rests on them.
• In single rack installations, stabilizers should be attached to the rack. In multiple rack in-
stallations, the racks should be coupled together.
• Always make sure the rack is stable before extending a server or other component from
the rack.

SuperServer 7049P-TR(T) User's Manual

• You should extend only one server or component at a time; extending two or more simul-
taneously may cause the rack to become unstable.
• When initially installing the server to a rack, test that the rail locking tabs engage to prevent
the server from being overextended. Have a rack lift in place as a precaution in case the
test fails.
Server Precautions
• Review the electrical and general safety precautions in Appendix B.
• Determine the placement of each component in the rack before you install the rails.

• Use a regulating uninterruptible power supply (UPS) to protect the server from power
surges and voltage spikes and to keep your system operating in case of a power failure.
• Allow any drives and power supply modules to cool before touching them.
• When not servicing, always keep the front door of the rack and all covers/panels on the
servers closed to maintain proper cooling.
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating temperature of
the rack environment may be greater than the room's ambient temperature. Therefore,
consideration should be given to installing the equipment in an environment compatible with
the manufacturer’s maximum rated ambient temperature (TMRA).

operation is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not arise due
to uneven mechanical loading.

Chapter 2: Rack Mount Installation
19
Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply circuitry
and the effect that any possible overloading of circuits might have on overcurrent protection
and power supply wiring. Appropriate consideration of equipment nameplate ratings should
be used when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself should be
grounded. Particular attention should be given to power supply connections other than the
direct connections to the branch circuit (i.e. the use of power strips, etc.).

2.3 Chassis Preparation
The chassis is shipped with the tower top cover and feet installed. Both must be removed
for before installing the rails.
Removing the Tower Top Cover
1. Locate the chassis cover lock (blue lever) at the rear of the chassis cover.
2. Slide the chassis cover lock to the right and push chassis cover forward.
3. Lift the chassis top cover off the chassis.

Removing the Chassis Feet
1. Place the chassis on its side.
2. Remove the screw holding a chassis foot in place.
3. The foot lock is a tab located in the center of the foot. It prevents the foot from sliding.
