• There are 4 or 24 dual personality interfaces comprising 4 or 24 1000base t mini gbic combo ports for each interface you can connect either to the 1000base t port or the mini gbic port the mini gbic ports have priority over the 1000base t ports this means that if a mini gbic port and the corresponding 1000base t port are connected at the same time the 1000base t port will be disabled 38

• Exposed power wire is dangerous use extreme care when connecting a dc power source to the device 43
• Keep the power supply switch and the switch s power switch in the off position until you come to the procedure for turning on the power 43
• Note check the power supply requirements in chapter 56 on page 463 and make sure you are using an appropriate power source 43
• Note the current rating of the power wires must be greater than 20 amps the power supply to which the switch connects must have a built in circuit breaker or switch to toggle the power 43
• Note this is only for the ac model of the switch 43
• Note this is only for the dc model of the switch 43

• A vlan virtual local area network allows a physical network to be partitioned into multiple logical networks devices on a logical network belong to one group a device can belong to more than one group with vlan a device cannot directly talk to or hear from devices that are not in the same group s the traffic must first go through a router 106
• Chapter 8 basic setting 106
• General setup continued 106
• In mtu multi tenant unit applications vlan is vital in providing isolation and security among the subscribers when properly configured vlan prevents one subscriber from accessing the network resources of another on the same lan thus a user will not see the printers and hard disks of another user on the same network 106
• Introduction to vlans 106
• Label description 106
• Note vlan is unidirectional it only governs outgoing traffic 106
• See chapter 9 on page 117 for information on port based and 802 q tagged vlans 106
• Vlan also increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain in traditional switched environments all broadcast packets go to each and every individual port with vlan all broadcasts are confined to a specific broadcast domain 106

• Label description 110
• On the switch as a layer 3 device an ip address is not bound to any physical ports since each ip address on the switch must be in a separate subnet the configured ip address is also known as ip interface or routing domain in addition this allows routing between subnets based on the ip address without additional routers 110
• Switch setup continued 110
• The switch needs an ip address for it to be managed over the network the factory default ip address is 192 68 the subnet mask specifies the network number portion of an ip address the factory default subnet mask is 255 55 55 110
• Use the ip setup screen to configure the default gateway device the default domain name server and add ip domains 110
• Xgs 4526 4528f 4728f user s guide 110

• Protocol based vlans 128
• Protocol based vlans allow you to group traffic into logical vlans based on the protocol you specify when an upstream frame is received on a port configured for a protocol based vlan the switch checks if a tag is added already and its protocol the untagged packets of the same protocol are then placed in the same protocol based vlan one advantage of using protocol based vlans is that priority can be assigned to traffic of the same protocol 128
