Precautions
Follow these precautionary steps:
• When selecting a fiber network facility, make sure the type of the connector and the fiber matches
the adopted fiber port.
• Be sure to install the dust cover if the fiber port is not connected to a fiber connector.
• Some invisible rays may be emitted from the fiber port if the fiber port is not connected to a fiber
connector or the dust cover is removed. Therefore, never stare at the fiber port directly.
• Never bend or curve a fiber when connecting it.
Installing a transceiver module
The installation of an XFP, SFP, and SFP+ module is similar. The following uses an SFP module as an
example.
CAUTION:
Do not touch the golden finger of an SFP module during installation.
To install an SFP module:
1. Put on an ESD-preventive wrist strap, and make sure it has close skin contact, and is well
grounded.
2. Take the SFP module out of the package. Close the clasp by pushing it up over the SFP+ module,
and then gently insert the SFP+ module into the interface slot until it clicks into place, as shown
in Figure 56 .
