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.
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.
