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.
Gigabit Ethernet Port Failover Speed
The Summit 200-48 switch Gigabit Ethernet port failover from the fiber link to the copper link takes 3-4
seconds. The Summit 200-48 switch Gigabit Ethernet port failover from the copper link to the fiber link
takes 1-2 seconds.
Summit 200-48 Switch Uplink Redundancy
Gigabit Ethernet uplink redundancy on the Summit 200-48 switch follows these rules:
• Ports 49 and 50 are Gigabit Ethernet ports that have redundant PHY interfaces, one mini-GBIC and
one 1000BASE-T connection for each port.
• Each of the uplink Gigabit Ethernet ports (49 and 50) can use either the mini-GBIC or
the1000BASE-T interface, but not both simultaneously.
• Only one interface on each port can be active at a time. For example, on port 49, 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 port 49, connect the active fibre and 1000BASE-T links to both the
RJ-45 and mini-GBIC interfaces of port 49. The switch defaults to the fiber link. If the fiber link fails
during operation, the switch automatically activates the redundant 1000BASE-T link.
NOTE
To support automatic failover between the fiber and copper ports, you must use an Extreme mini-GBIC
connector.
Full-Duplex
The Summit 200-48 switch provides full-duplex support for all ports. Full-duplex allows frames to be
transmitted and received simultaneously and, in effect, doubles the bandwidth available on a link. All
10/100 Mbps ports on the Summit 200-48 switch autonegotiate for half- or full-duplex operation.
