Asanté IntraCore 36000 Series Managed Gigabit Switches 5
Chapter 1: Introduction
The IntraCore 36000 Series Managed Gigabit Ethernet Switches are high-performance network switches used to
reduce network congestion and application response times. The 24-port (IC36240) and 48-port (IC36480) have
10/100/1000BaseT ports and four combination ports used for sharing with SFP mini GBICs. The switches also have
an SNMP-based management agent embedded on the main board. This agent supports both in-band and out-of-
band access for managing the switch.
These switches have a broad range of features for Layer 2 switching delivering reliability and consistent performance
for network traffic. The switches improve network performance by segregating them into separate broadcast domains
with IEEE 802.1Q compliant VLANs and provide multimedia applications with multicast switching and CoS services.
The IC36240 is a 24-port switch with 20 10/100/1000BaseT ports and 4 combination ports with 10/100/1000BaseT
and SFP MiniGBICs.
The IC36480 is a 48-port switch with 44 10/100/1000BaseT ports and 4 combination ports with 10/100/1000BaseT
and SFP MiniGBICs.
1.1 Features
The IntraCore 36000 Series Managed Gigabit Ethernet Switches support the following features:
1.1.1 Connectivity
24 or 48 10/100/1000 BaseT for Gigabit Ethernet integration into LAN networks.
Auto-negotiation enables each RJ-45 port to automatically select the optimum communication mode, either half
or full duplex, depending on the capability of the attached device. You can also configure the port manually.
Note: A copper Gigabit Ethernet port must use auto-negotiation to determine which link partners will be the master
and slave. It is not possible to force a copper port to 1000 Mbps/full duplex. Any Gigabit device connected to the
switch using copper cabling must support auto-negotiation. A fiber port may use auto-negotiation or may be forced to
1000/full duplex.
Independent RJ-45 10/100/1000BaseT ports with Asanté Auto-Uplink MDI/MDI-X selection.
Unshielded (UTP) cable supported on all RJ-45 ports: Category 3, 4 or 5 for 10 Mbps connections, Category 5 or
5e for 100 Mbps connections, and Category 5 or better for 1000 Mbps connections.
IEEE 802.3 Ethernet, 802.3u Fast Ethernet, 802.3z and 802.3ab Gigabit Ethernet compliance ensures
compatibility with standards-based hubs, network cards and switches.

Asanté IntraCore 36000 Series Managed Gigabit Switches 7
1.2 Switch Architecture
The Gigabit Ethernet Switches use a wire-speed, non-blocking switching fabric. This permits simultaneous wire-
speed transport of multiple packets at low latency on all ports. These switches also feature full-duplex capability on all
ports, which effectively doubles the bandwidth of each connection.
The switches use store-and-forward switching to ensure maximum data integrity. With store-and-forward switching,
the entire packet is received into a buffer and checked for validity before the packet is forwarded.
1.3 Network Management Options
The IntraCore 36000 Series Managed Gigabit Ethernet Switches provide a management agent with both local and
remote management. You can configure or monitor the switch using the embedded management software or by
using SNMP applications. You can manage the switch by a direct connection to the RS-232 console port (out-of-
band), or a network connection (in-band) using Telnet, SSH or the on-board web agent.
1.4 Ports
The IC36240 and IC36480 ports use 10/1000/10000BaseT technology. These RJ-45 ports operate at 10 Mbps or 100
Mbps, half or full duplex, or at 1000 Mbps, full duplex. All ports on both switches support automatic MDI/MDI-X
operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches
or hubs.
Each of these ports supports auto-negotiation, allowing the optimum transmission mode (half or full duplex), and data
rate (10, 100 or 1000 Mbps) to be automatically set. If a device connected to one of these ports does not support
auto-negotiation, the communication mode of that port can be manually configured.
Note: A copper Gigabit Ethernet port must use auto-negotiation to determine which link partners will be the master
and slave. It is not possible to force a copper port to 1000 Mbps/full duplex.
Any Gigabit device connected to the switch using copper cabling must support auto-negotiation.
A fiber port may use auto-negotiation or may be forced to 1000/full duplex.
Each port also supports auto-negotiation of flow control, so the switches can automatically prevent port buffers from
becoming saturated.
1.5 SFP Slots
The Small Form Factor Pluggable (SFP) ports are shared with four RJ-45 ports (ports 21 through 24 in the IC36240
and ports 45 through 48 in the IC36480). In its default configuration, if an SFP transceiver (purchased separately) is
installed in a slot with a valid link on its port, the associated RJ-45 port is disabled and SFP has priority. You can
configure the device to force the use of an RJ-45 port or SFP slot.

Setup Guide8
Chapter 2: Network Planning
A network switch allows simultaneous transmission of multiple packets using segmented architecture.
When network performance is reduced due to congestion at the network access point (for example, the network card
for a high-volume file server), the device experiencing congestion (a server, power user or hub) can be attached
directly to a switched port. Using full-duplex mode doubles the bandwidth of the segment to maximize throughput.
In networks based on repeater (hub) technology, the maximum distance between devices is limited. For Ethernet,
there may be up to four hubs between any pair of stations; for Fast Ethernet, the maximum is two. The switch
removes the distance limitiations by subdividing the network into smaller more manageable segments and linking
them to the larger network.
A switch can be configured in any Ethernet, Fast Ethernet or Gigabit Ethernet network to increase bandwidth using
conventional cabling and network cards.
2.1 Switch Applications
The IntraCore 36000 Series Managed Gigabit Ethernet Switches are designed to segment your network and provide
a wide range of options in setting up network connections and linking VLANs. The switch can operate as a stand-
alone network or in combination with other IntraCore switches in the backbone.
2.1.1 Collapsed Backbone
The IntraCore 36000 Series Managed Gigabit Ethernet Switches are designed for use in growing networks and
networks with legacy equipment. They are used in the following environments:
Mixed Ethernet
Fast Ethernet
Gigabit Ethernet
You can build on these basic configurations or by adding direct full-duplex connections to workstations or servers. For
future expansion, the switches can be connected to another hub or switch using one of the Gigabit Ethernet ports
built into the front panel or a Gigabit Ethernet port on a plug-in SFP transceiver.
As the following figure shows, the 24-port Gigabit Ethernet Switch operating as a collapsed backbone for a small
LAN. It is providing dedicated100 Mbps full-duplex connections to workstations and 1000 Mbps full-duplex
connections to power users and servers.

2.1.2 Network Aggregation Plan
With 24 or 48 parallel bridging ports (i.e., 24 or 48 distinct collision domains), the Gigabit Ethernet Switch can
collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput.
The following illustration shows that the 10/100/1000BaseT ports on the 24-port Gigabit Ethernet Switch are providing
1000 Mbps connectivity for up to 24 segments through Layer 2 switches. In addition, the switch is also connecting
several servers at 1000 Mbps.
2.1.3 Remote Connection with Fiber Cable
Fiber optic technology provides longer cabling distances than any other media type. A 1000BaseSX (MMF) link can
connect to a site up to 550 meters away, a 1000BaseLX (SMF) link up to 5 km, and a 1000BaseLH link up to 70 km.
This allows a Gigabit Ethernet Switch to serve as a collapsed backbone, providing direct connectivity for a
widespread LAN.
A 1000BaseSX SFP transceiver can be used for a high-speed connection between floors in the same building, and a
1000BaseLX SFP can be used to connect to other buildings in a campus setting. For long-haul connections, a
1000BaseLH SFP transceiver can be used to reach another site up to 70 km away.
The following figure illustrates the 24-port Gigabit Ethernet Switch connecting multiple segments with fiber cable.

2.1.4 VLAN Connections
VLANs are used to organize any group of nodes into separate broadcast domains. VLANs confine broadcast traffic to
the originating group and eliminate broadcast storms in large networks. They provide a secure and efficient network.
VLANs are based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it
belongs. Untagged VLANs can be used for small networks attached to a single switch. Tagged VLANs should be
used for larger networks, and all the VLANs assigned to the inter-switch links.
Using multiple spanning trees allows VLAN groups to maintain a stable path among all VLAN members. This reduces
the overall amount of protocol traffic crossing the network and provides a shorter reconfiguration time if any link in the
spanning tree fails.

2.2 Configuration Considerations
When planning your network, consider the following:
1. Full-duplex operation only applies to point-to-point access (for example, when a switch is attached to a
workstation, server or another switch). When the switch is connected to a hub, both devices must operate in
half-duplex mode.
2. Avoid using flow control on a port connected to a hub. This type of connection may cause dropped or
jammed signals and may degrade overall performance for the segment attached to the hub.
3. Consider power budget constraints when calculating the maximum cable length for your environment.
2.2.1 Optional Redundant Power Unit
The switches support an optional Redundant Power Unit (RPU) that can supply power to the switch in the event of
failure of the internal power supply.
2.2.2 Power Supply Receptacles
There is one power receptacle on the rear panel of each switch. The standard power receptacle is for the AC power
cord. The receptacle labeled “RPU” is for the optional Redundant Power Unit (RPU).
The following illustration shows the receptacle for the IC36240.

3.3 Site Requirements
Consider the following site requirements for proper installation.
3.3.1 Environmental Requirements
Choose a clean, dry, dust-free area location. Avoid direct sunlight, heat sources, or areas with high levels of
electromagnetic interference. Failure to observe these limits may cause damage to the switch and may void the
warranty.
3.3.2 Power
Make sure the power source adheres to the following guidelines:
Outlet: Properly grounded, located near the switch, and easily accessible
Power: Auto Switching 90-260 VAC
Frequency range: 50/60 Hz
3.3.3 Cooling and Airflow
The IC36000 switches use internal fans for air-cooling. Do not restrict airflow by covering or obstructing air vents on
the sides of the switch.
Operating Temperature: 32° to 104° F (0° to 40° C)
Relative Humidity: 10% to 90% non-condensing
3.3.4 Rack Mounting
Before mounting the switch in a rack, follow these general precautions:
Size: Make sure there is adequete space, including clearence and airflow, in the rack to accommodate the
size of the unit.
IC36240: 17.1 x 10.1 x 1.6 inches (434 x 257 x 41 mm)
IC36480: 17.5 x 14.0 x 2.6 inches (445 x 356 x 66 mm)
Temperature: The temperature within a rack assembly may be higher than the ambient room temperature.
Check that the rack-environment temperature is within the specified operating temperature range and remains
below 104°F (40°C).
Clearance: Be sure that no obstructions, such as other equipment or cables, block airflow to or from the vents of
the switch. Be sure there is adequate clearance for servicing the switch.
Mechanical Loading: Do not place any equipment on top of a rackmounted unit.
Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded.
Grounding: Rackmounted equipment should be properly grounded. Particular attention should be given to
supply connections other than direct connections to the mains.

Setup Guide14
3.4 Preparing for Installation
Switches can be mounted in a standard 19-inch equipment rack or on a flat surface. Follow these general precautions
when planning your equipment locations and connections.
The site needs the following:
Centrally located to the devices you want to link
Near a power outlet
Constant temperature within 32° to 104°F (0° to 40°C) and its humidity within 10% to 90%, non-condensing
Adequate space (approximately two inches) on all sides for proper air flow
Accessible for installing, cabling and maintaining the devices
Clearly visible status LEDs
Additional precautions:
Keep the front of the chassis free from obstruction and away from the exhaust air of other equipment. Electrical
equipment generates heat and the ambient room temperature should be enough to cool the equipment to
required operating temperatures.
Make sure twisted-pair cable is always routed away from power lines, fluorescent lighting fixtures and other
sources of electrical interference (for example, radios and transmitters).
Make sure that the unit is connected to a separate grounded power outlet that provides 100 to 240 VAC, 50 to 60 Hz,
is within 2.44 m (8 feet) of each device and is powered from an independent circuit breaker. As with any equipment,
using a filter or surge suppressor is recommended.

3.7.1 Hot Swapping Feature
The hot-swapping feature lets you install and replace the SFP transceivers while the system is operating; you do not
need to disable the software or shut down the system power.
Caution: When replacing an SFP transceiver, you must always disconnect the network cable before removing a
transceiver.
3.8 Applying Power
The system’s front panel LED display allows you to monitor the status of the switch. For LED information specific to
the switch’s model, see the “Interpreting LEDs” section in Chapter 4.
The back panel contains a 12 VDC jack for redundant power (optional) and the primary power socket.
Follow these steps to connect the switch.

Setup Guide18
1. Use the supplied power cord and plug the female end directly into the receptacle located at the back of the
device.
100-240V~,50-60HZ 2A
2. Plug the other end of the cord into a properly grounded electrical outlet.
3. Check the front-panel LEDs as the device is powered on to be sure the Power LED is lit. If not lit, check that the
power cable is correctly plugged in.
4. Connect the optional redundant power supply to the switch and to an AC power source by following the
instructions for the unit.
Warning: For International use: if you use power other than AC, you must use power cords that meet the appropriate
standards for the power you are using.
Note: If the power does not come on, refer to “Troubleshooting” information in Appendix A.
3.9 Ethernet Cabling
Based on the existing equipment in your network you need the following cables.
To ensure proper operation when installing the switch into a network, make sure that the current cables are suitable
with either 10BaseT, 100BaseTX or 1000BaseT operation. Check the following criteria against the current installation
of your network:
Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables with RJ-45 connectors; Category
3 or better for 10BaseT, Category 5 or better for 100BaseTX, and Category 5e or better for 1000BaseT
Protection from radio frequency interference emissions
Electrical surge suppression
Separation of electrical wires (switch related or other) and electromagnetic fields from data-based network wiring
Safe connections with no damaged cables, connectors or shields
RJ-45 Connector

When attaching a workstation to the switch, a standard straight through CAT5 cable may be used. No crossover
cable is needed on the MDI/MDI-X ports.
3.10 Connecting to the Console Port
The DB-9 serial port located on the front panel is used to connect to the switch for out-of-band console configuration.
The on-board configuration program can be accessed from a terminal or a PC running a terminal emulation program.
The pin assignments used to connect to the serial port are provided in the following tables.
3.10.1 Wiring Map for Serial Cable
The following table describes the serial cable wiring information.
Switch’s 9-Pin Serial Port Null Modem PC’s 9-Pin DTE Port
2 RXD (receive data) Å3 TXD (transmit data)
3 TXD Æ2 RXD (receive data)
5 SGND (signal ground) --- 5 SGND (signal ground)
The serial port configuration requirements are as follows:
Default Baud rate—auto-sensing (9.6 to 115K)
Character Size—8 Characters
Parity—None
Stop bit—One
Data bits—8

Chapter 4: Connecting Network Devices
The switch is designed to interconnect multiple segments (or collision domains). It can be connected devices using
optional SFP transceivers to network cards in PCs and servers, to hubs, routers or other switches.
4.1 Twisted-Pair Devices
Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. Use Category 5, 5e
or 6 cable for 1000BaseT connections, Category 5 for 100BaseTX connections, and Category 3, 4 or 5 for 10BaseT
connections.
4.1.1 Cable Guidelines
The RJ-45 ports on these switches support automatic MDI/MDI-X pinout configuration, so you can use standard
straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers or hubs).
See “Appendix C” for further information on cabling.
Caution: Do not plug a phone jack connector into an RJ-45 port. Doing this will damage the switch. Use only
twisted-pair cables with RJ-45 connectors that conform to FCC standards.
4.1.2 Connecting to PCs, Servers, Hubs and Switches
1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.
2. When device is a PC card and the switch is in the wiring closet, attach the other end of the cable segment to a
modular wall outlet that is connected to the wiring closet. (See “Connectivity Guidelines” later in this chapter.)
Otherwise, attach the other end to an available port on the switch.
3. Make sure each twisted pair cable does not exceed 328 ft (100m) in length.
Note: Using flow control on a port connected to a hub may degrade performance.
4. As each connection is made, the Link LED (on the switch) corresponding to each port lights up to indicate
that the connection is complete. (For more information, see “Interpreting LEDs” later in this chapter.)
