Installation Considerations
The Cisco 12008 offers the following mounting options:
•A 2-post, telco-style rack
•A 4-post, full-height equipment rack
•Shelf-top mounting
•Freestanding system
The installation procedures presented in this chapter pertain only to the first two of these
mounting options.
Before attempting to install your Cisco 12008, you should determine the mounting option
that you intend to use. It is assumed that you have already moved the shipping pallet
containing the router to the intended installation area.
Ensure that you have selected and prepared a compatible location for installing the router.
Consider the following:
•Will the selected location interfere with the flow of ambient cooling air through the
router?
You must ensure at least 6 inches (15.2 cm) of clearance in the front and back of the
router enclosure for the air intake and exhaust vents.
•Does the selected location provide a temperature-controlled, air-conditioned, and dust-
free operating environment?
•Are the power cables and power supplies to be used with your router compatible with
the source power available in the selected location?
Check the labels on the faceplate of the router’s power supply(ies) and ensure that the
source power available at the site is compatible.
•Is the proper source voltage (AC or DC) available at the site?
•Do you intend to install the router in a telco-style rack or a 4-post equipment rack?
•Have you allowed sufficient access and clearance around the router enclosure to meet
maintenance requirements?
