Introduction Introduction Overview The 24-Port Fast Ethernet PoE Switch contains 24 10BASE-T/100BASE-TX RJ-45 ports and two combination ports—10/100/1000BASE-T ports that operate in combination with Small Form Factor Pluggable (SFP) transceiver slots. All the 10BASE-T/100BASE-TX ports on this switch support IEEE 802.3af standard Power-overEthernet capabilities. Each port can detect connected 802.
Introduction W of power at the standard -48 DC voltage. Independent overload and short-circuit protection for each port allows the switch to automatically shut down a port’s power when limits are exceeded. Network devices such as IP phones, wireless access points, and network cameras, typically consume less than 10 W of power, so they are ideal for Power-over-Ethernet applications.

Network Planning Network Planning Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology.
Network Planning FIG. 7 MAX A/V Network Ports Port Number 1 - 24 Description Ports 1 - 24 can be used to connect AMX’s Master, AVMs, Breakout Boxes, WAP 200 Gs and/ or other Ethernet based devices requiring 10 or 100 Mbps data throughput. In addition, ports 1 - 24 support PoE with automatic power detection. • If the connected device does not support PoE the switch will not turn "On" power to that port.

Network Planning Making VLAN Connections This switch supports VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs.
Installing the Switch Installing the Switch Selecting a Site Switch units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. The site should: be at the center of all the devices you want to link and near a power outlet.
Installing the Switch Equipment Checklist After unpacking this switch, check the contents to be that sure you have received all the components. Then, before beginning the installation, be sure that you have all other necessary installation equipment. Package Contents 24-Port Fast Ethernet PoE Switch AC power cord Serial cable Rack mounting kit Quick Start Guide Hardware Installation and Software Configuration manuals can be downloaded via AMX.
Installing the Switch Mounting This switch can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. Mounting instructions for each type of site follow. Rack Mounting Before rack mounting the switch, pay particular attention to the following factors: Temperature: Since 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.

If more than one switch in the stack is selected as Master, or if no switches are selected, the stack will not function.
Installing the Switch Connecting to a Power Source To connect a switch to a power source: 1. Insert the power cable plug directly into the AC receptacle located at the back of the switch. 100-240V~ 50-60Hz 7.5A Power Socket FIG. 19 Power Receptacle 2. Plug the other end of the cable into a grounded, 3-pin socket, AC power source. For international use, you may need to change the AC line cord. You must use a line cord set that has been approved for the receptacle type in your country. 3.
Installing the Switch Connecting to the Console Port The DB-9 serial port on the switch’s front panel is used to connect to the switch for out-of-band console configuration. The command-line 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 table. 1 5 6 9 FIG.
Making Network Connections Making Network Connections Connecting Network Devices The PoE switch is designed to be connected to 10 or 100 Mbps network cards in PCs and servers, as well as to other switches and hubs. If 802.3af-compliant PoE devices are connected to the switch’s 10/100 Mbps ports, the switch automatically supplies the required power. Twisted-Pair Devices Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
Making Network Connections Connecting to MAX, AVM, WAPs, Breakout Boxes, Servers, Hubs and Switches 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. FIG. 21 Making Twisted-Pair Connections 2. If the device is a network 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 “Network Wiring Connections” on page 25.
Making Network Connections Network Wiring Connections Today, the punch-down block is an integral part of many newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follow. 1. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel. 2.
Making Network Connections 3. Connect one end of the cable to the LC port on the switch and the other end to the port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation. 13 13 14 15 16 17 18 19 20 21 22 23 24 23 14 25 26 24 LC fiber connector Link/A ct PW R PoE Diag 25 26 Stack ing Mode PoE/ Lin k FIG. 23 Making Fiber Port Connections 4.

Making Network Connections Cable Labeling and Connection Records When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption. To best manage the physical implementations of your network, follow these guidelines: Clearly label the opposing ends of each cable.
Troubleshooting Troubleshooting Diagnosing Switch Indicators Troubleshooting Chart Symptom Action PWR LED is Off • Internal power supply may be disconnected. Check connections between the switch, the power cord and the wall outlet. Diag LED is Amber • The system has detected a fault. Power cycle the switch to try and clear the condition. Diag LED is Flashing Amber • Check that all stacking cables are properly connected.
Troubleshooting In-Band Access You can access the management agent in the switch from anywhere within the attached network using Telnet, a web browser, or other network management software tools. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address.
Cables Cables Twisted-Pair Cable and Pin Assignments DO NOT plug a normal phone jack connector into any RJ-45 port. Use only twistedpair cables with RJ-45 connectors that conform with FCC standards. For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of wires. For 1000BASET connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes.

Cables Crossover Wiring If the twisted-pair cable is to join two ports and either both ports are labeled with an “X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be implemented in the wiring. (When autonegotiation is enabled for any RJ-45 port on this switch, you can use either straight-through or crossover cable to connect to any device type.
Cables Note that when testing your cable installation, be sure to include all patch cables between switches and end devices. Adjusting Existing Category 5 Cabling to Run 1000BASE-T If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try to correct the problem: 1. Replace any Category 5 patch cables with high-performance Category 5e or Category 6 cables. 2.
