3. Hold the screws and pull the QSM straight out of the chassis, as shown below.
4. Put the removed module into an antistatic bag or on a flat antistatic table.
5. Install a replacement module (see Installing a QSM).
Notes: If you do not want to install a new module, apply a blank plate over the slot
to avoid dust falling into the chassis. The installation method of blank plates is the
same as that of modules.
Replacing an IOM
The following section takes IOM-16SFP as an example to describe how to replace an IOM.
To replace an IOM, take the following steps:
1. Wear an electrostatic discharge (ESD) strap around your bare wrist and connect the strap to
an ESD point on the chassis. See ESD Prevention.
2. Remove all the cables connected to the module.
3. Use a cross screwdriver to loosen IOM screws until they pop out.
