Installing the Switch
Verifying Switch Chassis Installation
Procedure
Step 1
Verify that all empty module slots have blank faceplates installed and that the screws holding the plates in
place are tight. The blank faceplates optimize the air flow through the chassis and contain electromagnetic
interference.
Warning
Step 2
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.
Additional system diagnostic tests are 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. Refer to the "Online Diagnostics" section on page 3-19 for further information.
Tip
Online Diagnostics
The switch running Cisco IOS has many levels of online diagnostic capabilities. The online diagnostics are
divided into four categories:
• Bootup—Bootup diagnostics automatically run during bootup, module OIR, or switchover to a backup
• Background health—Monitoring diagnostic tests are continuously run by the system to monitor system
• On-demand online diagnostics—On-demand online diagnostics can be used to run any test from the
• Scheduled diagnostics—Scheduled diagnostics can be used to run any of the above tests at user-designated
For complete information on the online diagnostic tests and how to run them, refer to the software configuration
guide.

Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages and currents inside the chassis; they contain electromagnetic interference
(EMI) that might disrupt other equipment; and they direct the flow of cooling air through the
chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are
in place. Statement 1029
When prestaging systems in a nonproduction environment, we recommend that you run all diagnostic
tests, including the disruptive tests, to prescreen the systems for any failures.

Some of these tests are disruptive and will impact traffic flow.You must follow the on-demand diagnostic
