Internal fans draw cooling air into the chassis and across internal components to maintain an acceptable
operating temperature. (See
Figure 59: Cisco ASR 1004 Router Rear View with AC Power Supplies, on page
183
.) The fans are located at the rear of the chassis. A two-hole grounding lug is located on the side of the
chassis. Two power supplies, either two AC power supplies or two
–
48 VDC power supplies, are accessed
from the rear of the router.
You have already unpacked your chassis and read all the site requirements for your new equipment.
Proceed with the installation.
Note
Do not combine AC and
