As a connection is made, check the Link LED on the switch corresponding to
the port to be sure that the connection is valid.
The 1000BASE-SX, 1000BASE-LX, 1000BASE-LH fiber optic ports operate at 1
Gbps, full duplex, with auto-negotiation of flow control. The maximum length for
fiber optic cable operating at Gigabit speed will depend on the fiber type as listed
under
"1000 Mbps Gigabit Ethernet Collision Domain" on page 67 .
The 100BASE-FX fiber optic ports operate at 100 Mbps, full duplex, with auto-
negotiation of flow control. The maximum length for fiber cable operating at 100
Mbps is listed under
"100 Mbps Fast Ethernet Collision Domain" on page 68 .

ONNECTIONS
An optional 10 Gigabit transceiver (XFP, or SFP+) can be used for a backbone
connection between switches. Single-mode fiber ports require 9/125 micron
single-mode fiber optic cable. Multimode fiber optic ports require 50/125 or
62.5/125 micron multimode fiber optic cable. Each fiber optic cable must have
an LC connector attached at both ends.
1.
Remove and keep the port’s protective cover. When not connected to a fiber
cable, the cover should be replaced to protect the optics.
2.
Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber cables will impair the quality of the
light transmitted through the cable and lead to degraded performance on
the port.

ARNING
:
These switches use lasers to transmit signals over fiber optic
cable. The lasers are compliant with the requirements of a Class 1
Laser Product and are inherently eye safe in normal operation.
However, you should never look directly at a transmit port when it is
powered on.

ARNING
:
When selecting a fiber device, considering safety, please
make sure that it can function at a temperature that is not less than the
recommended maximum operational temperature of the product. You
must also use an approved Laser Class 1 transceiver.
