Verifying the Switch Chassis Installation

Verifying the Switch Chassis Installation

To verify the switch chassis installation, perform these steps:
Procedure
Step 1 Verify that the ejector levers of each module are fully closed (parallel to the faceplate) to ensure that the
supervisor engine and all the switching modules are fully seated in the backplane connectors.
Step 2 Check the captive installation screws of each module, and tighten any loose captive installation screws.
Step 3 Verify that all empty module slots and power supply bays have blanks installed properly. The blanks optimize
the air flow through the chassis and contain EMI.
Warning
Step 4 Turn on the power supply switches to power up the system. During the power-up sequence, the system performs
a series of bootup diagnostic tests.
What to do next
In case of a problem with any of the hardware components, refer to the
Additional system diagnostic tests are also available. These tests allow you to perform a complete sanity check
on the system prior to inserting the system into your network and to monitor the health of the system while
the system is running.
Tip When prestaging systems in a nonproduction environment, we recommend that you run all the diagnostic
tests, including the disruptive tests, to prescreen the systems for failures, if any.

Blank faceplates and cover panels serve three important functions— They prevent exposure to
hazardous voltages and currents inside the chassis; they contain EMI that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do not operate the system
until all cards, face plates, front covers, and rear covers are in place. Statement 1029
