Option 11C Mini Planning and Installation Guide
Commercial power requirements
The Option 11C Mini system is available with AC-power only.
The optimal installation of the AC-powered Option 11C Mini system
includes a direct connection to the electrical system in the building, provided
some requirements are met. Refer to AC-powered installation
later in this
chapter for detailed information. The Main Chassis and Chassis Expander can
share the same electrical breaker.
You can use an approved isolation transformer for AC-powered systems
when meeting the optimum requirements is not possible or is too expensive.
See “Alternative AC-powered installation” on page 58.
Refer to “Power consumption worksheets for the Option 11C Mini system”
on page 64 to determine the power consumption of the Option 11C Mini.
AC power installation for systems installed on a wall or table
Use a dedicated AC service panel with the Option 11C Mini system. Do not
connect equipment that is not related to the Option 11C Mini to this panel.
Keep all lighting, fans, motors, air conditioning equipment, and the like, as
“electrically separate” from the Option 11C Mini system as possible. The
Main Chassis and Chassis Expander can share the same AC breaker.
AC power installation for systems installed in a rack/cabinet
If other data communications equipment is in the same rack/cabinet as the
Option 11C Mini, power each piece of equipment from an isolated ground
outlet. The same service panel must service all outlets.
Power from each outlet must meet the input requirements of at least one
Option 11C Mini power supply, as listed in Tables 11 through 13. Check
power requirements for other system equipment. Install additional outlets if
you need to.
