Removing or installing the external SAS port
Learn how to remove or install an external serial-attached Small Computer System Interface (SAS) port
from or in the server.
Note:
Refill the external SAS port slot with either another external SAS port or a filler. Filling the empty
slot ensures proper air flow for cooling and maintains an optimal electromagnetic interference (EMI)
compliance.
