Rack-Mounting the 8270-600
This section describes rack-mounting the 8270-600. For information on
rack-mounting the 8270-800, see “Rack-Mounting the 8270-800” on page 2-7.
If you choose to rack-mount, you can use any EIA standard 19-inch rack. The rack
can be open or closed. However, if you use a closed rack, special provisions must
be made in order to ensure sufficient airflow through the machine. Decorative
covers on the front of the rack that impede airflow to the machine must be removed
or modified to allow sufficient airflow. Similarly, unvented rear covers that prevent
sufficient airflow out of the machine, or cause a back-pressure buildup due to other
machines discharging air, are prohibited.
The rack-mounting procedure tells you how to mount both the 8270-600 chassis
and the cable management bracket. The 8270-600 occupies three standard EIA
rack units. The 8270-600 cable management bracket can attach to any of the four
rack-mount screws depending how you want to route your cables.
Step 1. Using four rack-mount screws, mount the 8270-600 as shown in
Figure 2-4 on page 2-7.
Attention: When lifting the 8270-600 chassis, lift it using the outside
surfaces only.
Step 2. If the cable management bracket is to be used, mount it, using one of the
four rack-mounting screws.
