Summit 200-24 Switch Physical Features
The Summit 200-24 switch is a compact enclosure (see Figure 1) one rack unit in height (1.75 inches or
44.45 mm) that provides 24 autosensing 10BASE-T/100BASE-TX ports using RJ-45 connectors. It also
provides two 10/100/1000BASE-T Gigabit Ethernet uplink ports using RJ-45 connectors and two optical
ports that also allow Gigabit Ethernet uplink connections through Extreme 1000BASE-SX, 1000BASE-LX,
or 1000BASE-ZX Small Form Factor pluggable (SFP) Gigabit Interface Connectors (GBICs)—also known
as mini-GBICs—using LC optical fiber connectors.

NOTE
See “Summit 200-24 Switch LEDs” on page 18 for more details.
Console Port
Use the console port (9-pin, “D” type connector) for connecting a terminal and carrying out local
management.
Port Connections
The Summit 200-24 switch has 24 10BASE-T/100BASE-TX ports using RJ-45 connectors for
communicating with end stations and other devices over 10/100Mbps Ethernet.
The switch also has four Gigabit Ethernet uplink ports. These ports are labeled 25 and 26 on the front
panel of the switch. 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. The
Summit 200-24 switch supports the use of 1000BASE-SX, 1000BASE-LX, or 1000BASE-ZX mini-GBICs.
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.
Only two of the four Gigabit Ethernet uplink ports can be active at one time. For example, you can use
both 1000BASE-T ports, both mini-GBIC ports, or a combination of one 1000BASE-T port and one
mini-GBIC.
NOTE
For information on the mini-GBIC, see “Mini-GBIC Type and Hardware/Software Support” on page 23.
Summit 200-24 Switch Uplink Redundancy
Gigabit Ethernet uplink redundancy on the Summit 200-24 switch follows these rules:
•Ports 25 and 26 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 (25 and 26) can use either the mini-GBIC or the
1000BASE-T interface, but not both simultaneously.
•Only one interface on each port can be active at a time. For example, on port 25, 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 25, connect the active fibre and 1000BASE-T links to both the
RJ-45 and mini-GBIC interfaces of port 25. The switch defaults to the fiber link. If the fiber link fails
during operation, the switch automatically activates the redundant 1000BASE-T link.

Summit 200 Series Switch Overview
NOTE
To support automatic failover between the fiber and copper ports, you must use an Extreme mini-GBIC
connector.
Full-Duplex
The Summit 200-24 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 200-24 switch autonegotiate for half- or full-duplex operation.
