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.

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 22.
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.

Port Connections
The Summit 200-48 switch has 48 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 49 and 50 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 200-48 switch supports the use of 1000BASE-SX, 1000BASE-LX, or 1000BASE-ZX mini-GBICs.

NOTE
For information on the mini-GBIC, see “Mini-GBIC Type and Hardware/Software Support” on page 22.
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.
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.
