Guidelines for Connecting Ports
You can use Quad Small Form-Factor Pluggable Plus (QSFP+), Small Form-Factor Pluggable Plus (SFP+),
SFP transceivers, or RJ-45 connectors to connect the ports on the I/O modules to other network devices.
To prevent damage to the fiber-optic cables that can separate from their cables, we recommend that you keep
the transceivers disconnected from their fiber-optic cables when installing the transceiver in the I/O module.
Before removing such a transceiver from the switch, remove the cable from the transceiver.
To maximize the effectiveness and life of your transceivers and optical cables, do the following:
•
Wear an ESD-preventative wrist strap that is connected to an earth ground whenever handling transceivers.
The switch is typically grounded during installation and provides an ESD port to which you can connect
your wrist strap.
•
Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions
can shorten its useful life.
•
Keep the transceivers and fiber-optic cables clean and dust free to maintain high signal accuracy and to
prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should
be kept below 0.35 dB.
◦
Clean these parts before installation to prevent dust from scratching the fiber-optic cable ends.
◦
Clean the connectors regularly; the required frequency of cleaning depends upon the environment.
In addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry
cleaning techniques can be effective; refer to your site's fiber-optic connection cleaning procedures.
◦
Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other
contamination.
