Installing SFP+ Transceivers in the AT-VNC10S Adapter
Here are the guidelines to installing and cabling SFP+ transceivers in the 
AT-VNC10S adapter:
 SFP+ transceivers can be hot-swapped while the adapter is powered 
on. However, you should always disconnect the fiber optic cables first 
before removing a transceiver.
 You should install the transceiver before connecting the fiber optic 
cable.
 Fiber optic transceivers are dust sensitive. Always keep the plug in the 
optical bores when a fiber optic cable is not installed, or when you 
store the transceiver. When you do remove the plug, keep it for future 
use.
 Unnecessary removal and insertion of a transceiver can lead to 
premature failure.
 The connector on the fiber topic cable should fit snugly into the port on 
the adapter, and the tab should lock the connector into place.
 Do not remove the dust cover from a fiber optic port until you are ready 
to connect a fiber optic cable. Dust contamination can adversely affect 
the operation of a fiber optic port.
Warning
A transceiver can be damaged by static electricity. Be sure to 
observe all standard electrostatic discharge (ESD) precautions, 
such as wearing an antistatic wrist strap, to avoid damaging the 
device.
Warning
The fiber optic ports contain a Class 1 laser device. When the ports 
are disconnected, always cover them with the provided plug. 
Exposed ports may cause skin or eye damage.  L4
Note
The cable specifications for the SFP+ transceivers are found in the 
installation guides that ship with the devices.
Note
For information about cleaning a fiber optic connector on the 
AT-VNC10S adapter, see Appendix B “Cleaning Fiber Optic 
Connectors” on page 173.
