Cisco Nexus 9332D-GX2B - Setting Up an Optional Management Connection; Maintaining Transceivers and Optical Cables

Step 2 Insert the RJ-45 connector on the interface cable found in the accessory kit into the RS-232 port on the switch and insert
the DB-9 connector on the other end of the cable to the serial port on the console device.
What to do next
You can now perform the initial configuration for the switch (see the Cisco ACI Getting Started Guide).
Setting Up an Optional Management Connection
You can optionally set up an out-of-band management connection for monitoring and troubleshooting purposes.
To do this, depending on your switch, you connect either the RJ-45 management port or the SFP management
port on the switch to an external hub, switch, or router.
Before you begin
To prevent an IP address conflict, you must complete the initial configuration for the switch and establish an
IP address before you create the management connection.
Step 1 Connect the interface cable to a management port on the switch.
Step 2 Connect the other end of the cable to an external hub, switch, or router.
Maintaining Transceivers and Optical Cables
Transceivers and fiber-optic cables must be kept clean and dust free to maintain high signal accuracy and
prevent damage to the connectors. Contamination increases attenuation (loss of light) and should be below
0.35 dB.
Consider the following maintenance guidelines:
• Transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventative wrist strap that is
connected to the grounded chassis.
• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions
can shorten its useful life.
• Keep all optical connections covered when not in use. Clean them before using to prevent dust from
scratching the fiber-optic cable ends.
• Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other
contamination.
• 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 the fiber-optic connection cleaning procedures for your site.
• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a
microscope to determine if damage has occurred.
