Optics installation

WARNING: When working with optical fibers, follow all warning labels and always wear eye protection. Never

look directly into the end of a terminated or unterminated fiber or connector as it may cause eye damage.

1. Position the optic so it is in the correct position.

The optic has a key that prevents it from being inserted incorrectly.

2. Insert the optic into the port until it gently snaps into place.

NOTE: When you cable the ports, be sure not to interfere with the airflow from the small vent holes above and below

the ports.

Switch power-up

Supply power to the S4200-ON Series (S4248FB-ON and S4248FBL-ON) switch after you mount it in a rack or cabinet.

Reinspect your switch before power up. Verify the following:

● The equipment is properly secured to the rack. Dell EMC recommends properly grounding the switch.

● The ambient temperature around the unit, which may be higher than the room temperature, is within the limits specified for

the S4200-ON Series, see Specifications.

● There is sufficient airflow around the unit.

● The input circuits are correctly sized for the loads and that you use sufficient overcurrent protection devices.

● All protective covers are in place.

● Blank panels are installed if you do not install optional modules.

CAUTION: Do not power up the switch if you did not install a fan module.

NOTE: A US AC power cable is included for powering up an AC power supply. You must order all other power cables

separately.

NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap

when handling the switch and its components.

Power up sequence

When the switch powers up, the fans immediately come on at high speed. The fan speed slows as the switch continues to boot

up.

After switch installation

To configure your switch, after you have securely installed and powered on the S4200-ON Series (S4248FB-ON and

S4248FBL-ON) switch, see your open network installation environment (ONIE)-compatible operating system documentation

at www.onie.org. For more information about working with the ONIE environment, see your switch documentation at
