Chapter 3: Setup and Installation
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
over-current protection and power supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern. See the
power calculation tables in
Appendix A .
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 (such as the use of power strips and so
on).
NOTE: It is recommended that you seek the advice and assistance of a licensed electrician
that can advise you on best practices for ensuring that the electrical supply and the rack are
joined to a
Common Bonding Network .
Professional documents on grounding techniques include:
• ANSI/TIA-942 – Telecommunications Infrastructure Standard for Data Centers
• J-STD-607-A-2002 – Commercial Building Grounding (Earthing) and Bonding
Requirements for Telecommunications
• IEEE Std 1100™-2005 (IEEE Emerald Book) – IEEE Recommended Practice for
Powering and Grounding Electronic Equipment
Installing the System Into a Rack
This section provides information on installing the 8U SuperBlade into a rack. There are
a variety of rack units on the market, meaning the procedure may differ slightly. Refer to
the Enclosure Template that was included with the system for help.
Rack Mounting Hardware
The following is a list of rack mounting hardware you will need for rack setup and
installation:
• Two rail assemblies (one for each side of the enclosure)
• Two handles
• Four roundhead screws for fastening the enclosure ears to the rack
• Eight flathead screws and washers for mounting the rails to the rack
