Unpacking And Inspecting A New Switch - Cisco Nexus 7706 Hardware Installation Manual

Unpacking and Inspecting a New Switch

Step 2
If the rack has bonded construction, connect it to the earth ground. This action enables you to easily ground the switch
and its components and to ground your electrostatic discharge (ESD) wrist strap to prevent damaging discharges when
you handle ungrounded components before installing them.
Step 3
If you need access to the source power at the rack, include either AC power receptacles or a DC power interface unit
(PIU) with the amperage required by the switch that you are installing. For amperage and other circuit requirements, see
Electrical Circuit Requirements for Cisco Nexus 7000 and 7700
If you are using DC power, be sure that the DC power supply is grounded and that there is direct access to the facility
DC power or indirect access though a power interface unit (PIU). You must connect the DC power supply to the earth
ground before you connect it to the facility DC power.
Take care when connecting units to the supply circuit so that wiring is not overloaded.
Warning
Statement 1018
If you are using the combined power mode or power-supply redundancy, you need only one power source. If
Note
you are using input-source redundancy or full redundancy, you need two power sources.
Unpacking and Inspecting a New Switch
Before you install a new chassis, you need to unpack and inspect it to be sure that you have all the items that
you ordered and verify that the switch was not damaged during shipment. If anything is damaged or missing,
contact your customer representative immediately.
When you handle the chassis or its components, you must follow ESD protocol at all times to prevent
Caution
ESD damage. This protocol includes but is not limited to wearing an ESD wrist strap that you connect to
the earth ground.
Do not discard the shipping container when you unpack the switch. Flatten the shipping cartons and store
Tip
them with the pallet used for the system. If you need to move or ship the system in the future, you will
need these containers.
Step 1 Compare the shipment to the equipment list that is provided by your customer service representative and verify that you
have received all of the ordered items.
The shipment should include boxes for the following:
• System chassis, which includes the following installed components:
◦ 1 or 2 supervisor modules
◦ 1 to 4 I/O modules
◦ Up to 6 fabric modules
◦ 3 fan trays
◦ 1 to 4 power supply units
