Replacing a CMCC Module (Tellabs 7345 Switch only)
6.14 Replace a CMCC module by performing the following steps:
__ 1. Perform the steps in the Module Replacement Pre-Checklist,
page 2-92.
__ 2. Use an antistatic wriststrap connected to the shelf to ensure you are
adequately grounded while installing or servicing the system. Do this
to avoid damaging components sensitive to static electricity. Connect
the antistatic wriststrap to the shelf as shown in Figure 6.1, page 2-94.
__ 3. Ensure the Power/Status LED is not flashing green. If the LED is
flashing, wait for it to stop before continuing.
Warning:
The Tellabs 7345 Switch will be reset if this procedure is not followed.
