Guidelines for Connecting Ports

You can use C Form-factor Pluggable (CFP), Quad Small Form-Factor Pluggable (QSFP+, QSFP28, or
QSFP-DD), or Small Form-Factor Pluggable (SFP, SFP+ or SFP28) transceivers or RJ-45 connectors to
connect the ports on the line cards to other network devices.
For information about the transceivers currently being used with the switch, use the show inventory all
command.
Prevent damage to the fiber-optic cables that can separate from their cables. Keep the transceivers disconnected
from their fiber-optic cables when installing the transceiver in the line card. 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.
• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions
• Keep the transceivers and fiber-optic cables clean and dust free to maintain high signal accuracy and to

prevent damage to the connectors. Contamination causes increased attenuation (loss of light), 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.
