Before you install your Cisco 12012, your installation site should already be prepared.
Ensure that you have planned a compatible location for the Cisco 12012 and that you have
considered the following:
•
The location does not block the cooling air intake (front of the system) and exhaust vents
(rear of system). There must be at least 6 inches (15.8 cm) of clearance in the rack for
the air intake and exhaust vents.
•
The location is a temperature-controlled, air-conditioned, dust-free area.
•
You have checked the power cables and power supplies for compatibility with your
power service; check the labels on the equipment and ensure that the power service at
your site is suitable for the Cisco 12012.
•
The proper source voltage (AC or DC) receptacles have been provided.
•
Maintain at least 24 inches (61 cm) of clearance in front of the frame for working with
line cards, blower modules, power supplies, or attaching network interface cables or
