Removing SFP or SFP+ Transceiver Modules

Removing SFP or SFP+ Transceiver Modules
Procedure
Step 1 Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.
Step 2
Disconnect the cable from the SFP transceiver module. For reattachment, note which cable connector plug is
send (Tx) and which is receive (Rx).
Step 3
Insert a dust plug into the optical ports of the SFP transceiver module to keep the optical interfaces clean.
Step 4 If the module has a bale-clasp latch, pull the bale out and down to eject the module. If you cannot use your
finger to open the latch, use a small, flat-blade screwdriver or other long, narrow instrument to open it.
Step 5
Grasp the SFP transceiver module, and carefully remove it from the slot.
Step 6 Place the SFP transceiver module in an antistatic bag or other protective environment.

Verifying Switch Chassis Installation

Procedure
Step 1 Ensure that the unused power supply unit has a metal cover plate installed.
Step 2
Turn on 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 CLI.

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.

You can also run on-demand online diagnostics to perform a sanity check on the system hardware. Some
of these tests are disruptive and will impact traffic flow.You must follow the on-demand diagnostic
guidelines exactly to avoid false failures.
