Cisco Systems Cisco uBR10012 manual Using Power Strips with a Rack-Mount Installation

Chapter 2 Preparing for Installation

Site Requirements

•If you are also using the optional AC-input power shelf, it should be installed immediately below the Cisco uBR10012 chassis for power cabling convenience. However, install the AC-input power shelf after you install the chassis.

•Ensure that the router is connected to earth ground during normal use.

•Frame ground should be tied to the single building point ground, or the closest return point to building ground.

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Using Power Strips with a Rack-Mount Installation

Some equipment racks provide a power strip along the length of one of the mounting strips. If your rack has a power strip, consider the position of the strip when planning fastener points to ensure that you can slide cards straight out of their respective slots. If the power strip does impair a rack-mount installation, remove the power strip before installing the chassis in the rack, and then replace it after the chassis is installed. See the “General Rack Installation Guidelines” section on page 3-3for additional information about rack-mounting your system.
