Figure 13. Install the Fan Module

CAUTION:

DO NOT mix airflow directions. All fans must use the same airflow

direction (I/O to PSU side or PSU to I/O side).

CAUTION:

Check the fans at six-month intervals and replace them as necessary. To

accurately determine replacement intervals, regularly monitor the speeds of the

cooling fans.

Installing the SFP+ and QSFP+ Optics

The S4048T-ON system has 48 RJ-45 ports and six quad small form-factor pluggable plus

(QSFP+) optical ports.

For a list of supported optics, see the S4048T-ON Specification Sheet at

www.dell.com/support/

CAUTION:

ESD damage can occur if the components are mishandled. Always wear

an ESD-preventive wrist or heel ground strap when handling the system and its

components.

WARNING:

When working with optical fibers, follow all the 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.

Position the optic so it is in the correct position. The optic has a key that prevents it

from being inserted incorrectly.

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