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.
Supported SFP and SFP+ Transceivers
The following types of SFP transceivers are available from Cisco Systems and are supported on the
Cisco MDS 9100 Series:
•
•
•
•
Switches running Cisco MDS SAN-OS Release 1.1(1a) or later and MDS NX-OS Release 4.1(1b) or
Note
later support combination Fibre Channel/Gigabit Ethernet SFP transceivers.
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.
SFP tranceivers can also be used in extended distances, but it would depend on the allocation of available
Buffer-To-Buffer (B2B) credits on specific ports in the switch. For more information on Buffer-to-Buffer
(B2B) credits, see the Configuring Interface Buffers chapter in the Cisco MDS 9000 Family NX-OS
Interfaces Configuration Guide.
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
9100 Series.
