so that the switch can link to other switches. These ports are also commonly referred to as mini 10GigaBit
Interface Converter ports. The term SFP+ is used in this guide.
• The SFP+ ports are compatible with the following Cisco SFP 1G optical modules MGBSX1,
MGBLH1, MGBT1, as well as other brands.
• The Cisco SFP+ 10G optical modules that are supported in the Cisco switches are: SFP-10G-SR,
SFP-10G-LR, SFP-10G-SR-S, and SFP-10G-LR-S.
• The Cisco SFP+ Copper Cable modules that are supported in the Cisco switches are:
SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M.
• The SFP+ port is a combination port, shared with one other RJ-45 port. When the SFP+ is active,
the adjacent RJ-45 port is disabled.
• The LEDs of the corresponding RJ-45 port flash green to respond to the SFP interface traffic.

performing self-tests, or acquiring an IP address. If the LED flashes Amber, the switch has detected a
hardware failure, a firmware failure, and/or a configuration file error.
• Flash = LED going off and then on again.
• According to unit ID of the unit. This means
• Unit 1 (if not active unit) - system LED will flash 1 time
• Unit 2 (if not active unit) - system LED will flash 2 times
• Unit 3 - system LED will flash 3 times
• Unit 4 -system LED will flash 4 times;
• The duration of each flash (LED off time) will be as follows:
• LED off time (in each flash) ~ 0.5 seconds.
• "Interim" LED on (between 2 LED offs) ~ 0.5 seconds
