SFP transceivers are field-replaceable. You can use any combination of SFP transceivers that are
supported by the switch. The only restrictions are that SWL transceivers must be paired with SWL
transceivers, and LWL transceivers with LWL transceivers, and the cable must not exceed the stipulated
cable length for reliable communications.
For the list of supported SFP transceivers, see the
Cisco MDS 9000 Family Release Notes for Cisco MDS
NX-OS Releases
. For more information about a specific Cisco SFP transceiver, see the
Specifications” section on page 1-4
. SFP transceivers can be ordered separately or with the Cisco MDS
9148S Switch.

The flashing green light turns on automatically when an external loopback is detected that causes the interfaces to be isolated.
The flashing green light overrides the beacon mode configuration. The state of the LED is restored to reflect the beacon mode
configuration after the external loopback is removed.
