Summit 200 Automatic Failover - Extreme Networks Summit 300-24 Hardware Installation Manual

Summit Switch Models
A Summit 200-24fx switch has 24 100BASEFX ports for communicating with end stations or other
devices over 100Mbps Ethernet.
The switch also has four Gigabit Ethernet uplink ports, of which only two can be used at any one time.
These combination ports are labeled 25 and 26 on the front panel of the Summit 200-24 or 200-24fx and
labeled 49 and 50 on the front panel of the Summit 200-48. Two of the ports are 10/100/1000BASE-T
ports using RJ-45 connectors. The other two ports are unpopulated receptacles for mini-SFP GBICs,
using optical fibers with LC connectors. All models of the Summit 200 support the use of 1000BASE-SX,
1000BASE-LX, or 1000BASE-ZX mini-GBICs.
The uplink ports can be used as the interconnect ports in a Summit switch stacked configuration. For
more information about configuring and operating a Summit switch stack, see the ExtremeWare Software
User Guide.
NOTE
Only mini-GBICs that have been certified by Extreme Networks (available from Extreme Networks)
should be inserted into the mini-GBIC receptacles on the Summit 200 series switch.

Summit 200 Automatic Failover

The Summit 200 switch supports an automatic failover from an active fiber port to a copper backup or
from an active copper port to a fiber port. If one of the uplink connections fails, the Summit 200 uplink
connection automatically fails over to the second connection. On the Summit 200-24 and 200-48
switches, the preferred medium is fiber and cannot be configured. On the Summit 200-24fx switch, the
switch determines whether the port uses the copper or fiber connection based on the order in which the
connectors are inserted into the switch.
On the Summit 200-24 and 200-24fx switches, ports 25 and 26 are the Gigabit Ethernet ports that have
the redundant PHY interfaces. On the Summit 200-48 switch, ports 49 and 50 have the redundant PHY
interfaces. Each port has one mini-GBIC and one copper 1000BASE-T connection.
To set up a redundant link on one of the uplink ports, connect the active fiber and 1000BASE-T links to
both the RJ-45 and mini-GBIC interfaces of that port.
Uplink Redundancy on the Summit 200-24 Switch and Summit 200-48 Switch
On the Summit 200-24 and 200-48 switches, Gigabit Ethernet uplink redundancy follows these rules:
• Only one interface on each port can be active at a time. For example, on port 25 of the Summit
200-24 switch, with both the mini-GBIC and 1000BASE-T interfaces connected, only one interface can
be activated. The other is inactive. If both interfaces are connected, the switch defaults to the fiber
interface (mini-GBIC) and deactivates the 1000BASE-T interface.
• If only one interface is connected, the switch activates the connected interface.
• To set up a redundant link on an uplink port, connect the active fiber and 1000BASE-T links to both
the RJ-45 and mini-GBIC interfaces of the port. The switch defaults to the fiber link. If the fiber link
fails during operation, the switch automatically activates the redundant 1000BASE-T link.
NOTE
When configuring the Summit 200-48 switch, all ports specified as mirrored ports and mirroring port, or
ACL ingress ports and egress port, must belong to the same port group. Port group 1 consists of ports
1 through 24 and port 49; port group 2 consists of ports 25 through 48 and port 50.
