Drive-Side SAS Expansion Port LEDs
The EF570 controller canister is equipped with two SAS expansion ports that are used to connect
expansion-drive shelves to the EF570 controller shelf. Figure 52 shows the SAS expansion port LEDs.
Figure 52) LEDs for drive expansion ports.
Table 21 defines each drive-side LED. The definitions for port EXP1 are repeated for port EXP2.
Table 21) Drive expansion port LED definitions.
At least one of the four PHYs in
the output port is working, but
another PHY cannot establish
the same link to the expansion
output connector.
Port is optimal (all PHYs in the
port are up).
EF570 Optional Host Interface Cards
The EF570 supports several host interface expansion options, including SAS, FC, iSCSI, and IB. This
section provides the detailed LED status definitions for all the HIC choices.
