Cisco Nexus 7000 Series Manual de instrucciones de instalación
When you replace the power supplies, remember to engage all of the safety features on each supply.
The power supplies feature the following three safety interlock features:
•
A safety interlock on/off switch (see Figure 6) prevents the power supply from being removed
from the chassis when the power supply switch is in the on (|) position. When the switch is on, a
metal tab extends into a slot in the chassis. When the switch is turned off (O), the tab retracts into
the power supply housing and clears the slot.
•
A captive installation screw at the top of the power supply front panel provides electrical
grounding and prevents the power supply from vibrating or sliding out of the bay and dislodging
from the power connectors in the backplane.
•
A cable retention clip prevents the power supply power cord from being accidentally pulled out
of the power supply socket.
For a complete description of the power supply, refer to the Cisco 7000 Hardware Installation and
Maintenance or Cisco 7507 Hardware Installation and Maintenance publications.

Equipment Rack Considerations

This kit is suitable for mounting the chassis in most 19-inch 2-post, 4-post, or Telco-type racks that
conform to the EIA-310-C standard. The brackets, which support the chassis, cantilever off two rack
posts. You can mount the chassis with either end approximately flush with the two rack posts, or, in
Telco-type installations, you can center-mount the chassis. Before proceeding, review the guidelines
in this section and ensure that you have planned your installation carefully to avoid hazards such as
top-heavy or unbalanced racks, or cables or equipment that obstruct traffic paths or access to
equipment.
Before using a particular rack, check for obstructions (such as a power strip) that could impair access
to the processor modules or power supplies at the interface processor end, or to the chassis panels
that provide access to the internal field replaceable units (FRUs) at the non-interface processor end
of the chassis. Figure 7 shows the chassis footprint and outer dimensions, and the clearance required
to remove or install FRUs.
