Summit 400-48t Switch Physical Featu res
The Summit 400-48t switch is a compact enclosure (see Figure 1) one rack unit in height (1 .73 inches or
44.0 mm) that provides 48 autosensing 10/100/1000BASE-T ports using RJ-45 connectors. The switch
also has four fiber ports that allow Gigabit Ethernet uplin k connections through Extreme 1000BASE-SX,
1000BASE-LX, or 1000BASE-ZX SFP mini-GBICs using LC connectors. The four fiber ports and the first
four of the 10/100/1000BASE-T ports are designed as shared, or combination ports for uplink
redundancy. When sharing ports, only the fiber port or on ly the copper port can be active at the same
time. For more information on cablin g and configuring this fea ture, see “Uplink Redundancy” o n
page 27.
Summit 400-48t Switch Front View
Figure 1 shows the Summit 400-48t switch front view.
Figure 1: Summit 400-48t switc h front view
The front panel consists of:
LEDs—For a description of the LEDs and their behavior, see “Summit 400-48t Switch LEDs” on page 23.
Fiber uplink ports—For more information about these four ports, see “Min i-GBIC Type and Support”
on page 24.
10/100/1000BASE-T ports—For more information about these 48 ports, see “Port C onnections” on
page 27.
Console Port—Use the console port (9-pin, “D” type connector) to attach a term inal and ac cess the CL I
through a serial connection. Use the console port to carry out local management.

Summit 400-48t Switch Overview and In stallation
Summit 400-48t Switch Rear View
Figure 2 shows the rear view of the Summ it 400-48t switch.
Figure 2: Summit 400-48t switch rear view
The rear panel consists of:
• An option slot for the dual 10 G igabit uplinks
To install this option, see “Instal ling Optional Feat ures” on page 39.
• The management port
The 10/100/1000BASE-T Ethernet management port communicates directly with the CPU of the
switch, bypassing the switch. Connect an Ethernet cable directly from a laptop into the management
port to view and locally manag e the switch configurations.
Do not assign an in-b and IP address to th e managem ent port VL AN. The ma nagement p ort VLAN is
an out-of-band VLAN, so if it is assigned an in-band IP address (an address where the source and
destination are in the same subnet), the switch treats it as a normal VLAN and attempts to route
traffic through it.
Extreme Networks does not recommend that you use the management po rt to route traffic to any
front panel port on the switch. The managem ent port is designed only for sw itch management
purposes.
There are two LEDs for the management port, located in the bottom corners of the port. The LED on
the bottom right turns solid green when a cable is inserted and the port detects a link. The LED on
the bottom left blinks green when there is transmission activity on the link.
• A compact flash slot
This slot is currently not supported but is reserved for future use.
• Two high-performance stacking ports
These ports are currently not supported but are reserved for future software features.
• Vents for the internal po wer supply fan.
• The connector for the optional Extreme External Power Supply System.
For further information abou t this feature, see “Installing Opti onal Features” on page 39.
• AC Power Socket
The Summit 400-48t switch automatically adjusts to the supply voltage. The power supply operates
from 100 VAC to 240 VAC.

Total optical system budget for the LX mini-GBIC is 13.5 dB. Measure cable plant losses with a 1310 nm
light source and verify this to be within budget. When calculating the maximum distance attainable
using optical cable with a specified loss per kilo meter (for example 0.25 dB/km) Extreme Networks
recommends that 3 dB of the total budget be reserved for losses induced by cable splices, connectors,
and operating margin. Thus, 10.5 dB remains av ailable for cable induced attenuatio n. There is no
minimum attenuation or minimum cable length restriction.

Port Connections
The Summit 400 -48t switch ha s 48 copper 10 /100/1000BA SE-T ports using RJ-45 conn ectors for
communicating with end statio ns and other devices over 1 0/100/1000 Mbps Ethe rnet.
The switch provides full-duplex support for all ports. Full- duplex allows frames to be transmitted and
received simultaneously and, in effect, doubles th e bandwidth available on a link. All 10/100/100 0
Mbps ports on the Summit 4 00-48t switch auton egotiate for half- or f ull-duplex operation.
Uplink Redundancy
The four fiber ports and the first four of the 10/100/1000BASE-T ports are designed as combination
ports for uplink redundancy. When sharing ports, only the fiber port or only the copper port can be
active at the same time. If copper port 1 goes down while transmittin g packets, fiber port 1X activates
and becomes the primary link. Se e Figure 4 for a diagram of these com bination ports.

Summit 400-48t Switch Overview and In stallation
The switch determines whether the port is the primary or redundant port based upon the order in
which the cables are inserted into the switch. When the switch senses that cables are in both the fiber
and corresponding copper port, the switch enables the uplink redundancy feature. For example, if you
insert mini-GBICs into ports 1X and 3X first, and then connect copper ports 1 and 3, the switch assigns
ports 1 and 3 as redundant ports.
Figure 4: Redundancy cabling
You can override the configurati on and behavior of these ports through the CLI. Us ing the CLI, you can
set a preference for either fiber or copper. You can also turn off port redundancy using the force option.
If a combination port fails to link, determine whether the force option is in effect. For more information
about using the CLI to set redundancy priority, see “Configuring Ports” on page 81.
The Summit 400-48 switch G igabit Ethernet port failover from the fiber link to t he copper link takes 4-5
seconds. The Summit 400-48t sw itch Gigabit Eth ernet port failover from the copper link to the fiber l ink
takes 2-3 seconds.
NOTE
To support automatic failove r between the fiber and co pper ports, you must use a n Extreme mini-GBIC
connector.
Software Overview
Virtual LANs (VLANs)
ExtremeWare has a VLAN feature that enables y ou to construct your broadcast domains without being
restricted by physical connections. A VLAN is a group of location- and topolog y-independent devices
that communicate as if they were on the same physical local area network (LAN).
Implementing VLANs on your network has the following three advantages:
• VLANs help to control broadcast traffic. If a device in VLAN Marketing transmits a broadcast frame,
only VLAN Marketing devices receive the frame.
• VLANs provide extra security. Devices in VLAN Marketing can only communicate with devices on
VLAN Sales using routing services.
• VLANs ease the change and movem ent of devices on netw orks.

ExtremeWare 7.2e Installation and User Guide 29
For more information on VLANs, see Cha pter 5.
Spanning Tree Protocol
The switch supports the IEEE 80 2.1D Spanning Tree Protocol (STP), which is a bridge-based mechanism
for providing fault tolerance on networks. STP ena bles you to implement parallel paths for network
traffic, and ensure that:
• Redundant paths are disabled when the main paths are operational.
• Redundant paths are enabled if the main traffic paths fail.
A single spanning tree can span m ultiple VLANs.
For more information on STP, see Chapter 11.
Quality of Service
ExtremeWa re has Policy-Based Quality of Service (QoS) features that enable yo u to specify service levels
for different traffic groups. By default, all traffic is assigned the normal QoS policy profile. If needed,
you can create other QoS policies and apply them to different traffic types so that they have different
guaranteed minimum bandwidth, maximum bandwidth, and priority. For more informa tion on Quality
of Service, see Chapter 7.
Unicast Routing
The switch can route IP traffic between the VLANs that are configured as virtual router interfaces. Both
dynamic and static IP routes are maintained in the routing table. Th e following routing protocols are
supported:
• RIP version 1
• RIP version 2
• OSPF version 2
For more information on IP unic ast routing, see Chapter 12.
IP Multicast Routin g
The switch can use IP multicasti ng to allow a single IP ho st to transmit a packet to a group of IP hosts.
ExtremeWare supports mul ticast routes that are learned by way of the Protocol Independent Multicast
(sparse mode). For more information on IP multicast routing, see Chapter 14.
Load Sharing
Load sharing allows you to increase bandwidth and resiliency by usi ng a group of ports to carry traffic
in parallel between systems. The load sh aring algorithm allows the sw itch to use multiple ports as a
single logical port. For example, VLANs see the load -sharing group as a single virtual po rt. The
algorithm also guarantees packet sequencing between clients. For more information on load sharin g, see
Chapter 4.

Summit 400-48t Switch Overview and In stallation
ESRP-Aware Switches
Extreme switches that are not running ESRP, but are connected on a network that has other Extreme
switches running ESRP are ESRP-aware. When ESRP-aware switches are attached to ESRP-enabled
switches, the ESRP-aware switches reliably perform fail -over and fail-back scenarios in t he prescribed
recovery times. No configuration of th is feature is necessary.
NOTE
If you disable EDP on the switch, the switch is no lon ger ESRP-aware.
If Extreme switches running ESRP are connected to layer 2 switches that are not manufactured by
Extreme Networks (or Extreme switches that are not running ExtremeWare 4.0 or later), the fail-over
times seen for traffic local to the segment may appear longer, depending on the application involved
and the FDB timer used by the other vendor ’s layer 2 switch. As such, ESRP can be used with layer 2
switches from other vendors, but the recovery times vary.
The VLANs associated with the ports connecting an ESRP-aware switch to an ESRP-enabled switch
must be configured using an 802.1Q tag on the con necting port, or, if only a single VLAN is involved, as
untagged.
To display ESRP-aware information, us e the following command:
show esrp-aware [vlan <vlan name>]
The display includes the group number, MAC address for the master of the group, and age of the
information.
Software Licensing
Some Extreme Networks products have capabilities that are enabled by usin g a license key. Keys are
typically unique to the switch, and a re not transferable. Keys are stored in NVRAM and, once entered,
persist through re boots, softwa re upgrad es, and reconfiguration s. The following sections describe the
features that are associated with license keys.
Router Licensing
Some switches support software licensing for different levels of router functionality. In the
Summit 400-48t, routing protocol support is separated into two sets: Edge and Advanced Edge. Edge is
a subset of Advanced Edge.
Edge Functionality
Edge functionality requires no license key. Extreme switches that ship with an Edge license, do not
require a license key. Edge functionality includes all sw itching functions, and al so includes all a vailable
layer 3 QoS, access list, and ESRP functions. L3 routing functions include support for:
• IP routing using RIP version 1 and/ or RIP version 2
• IP routing between directly attached VLANs
• IP routing using static routes
• ESRP-aware
