Back to Contents Page Introduction Dell™ PowerConnect™ 5224 Systems User's Guide Features Front-Panel Components Back-Panel Descriptions Management Features The Dell™ PowerConnect™ 5224 Gigabit Ethernet Managed Switch offers the following features: l 24 10/100/1000BASE-T auto-sensing Gigabit Ethernet switching ports l Four 10/100/1000BASE-T ports operate in combination with four Small Form Factor Pluggable (SFP) transceiver slots l IEEE 802.3u, IEEE 802.3z, and IEEE 802.
Front-Panel Components The front panel of the switch contains the console port, all of the Ethernet ports, and LEDs. As shown in the following figure, the switch has three system LEDs and one LED for each port. The following sections describe the front panel in more detail. PWR LED The PWR (power) LED shows the general operating status of the system. Indicator states include: l Off — The unit is off with no power connections. l Green — The unit's internal power supply is operating normally.
Back-Panel Descriptions The back panel of the system contains the AC power receptacle and the RPS connector. AC Power Receptacle The switch automatically adjusts its power setting to any supply voltage in the range of 90 to 240 V alternating current (VAC). RPS Connector Connect the optional RPS to the RPS connector. If the switch's internal power unit fails, the redundant power system automatically supplies power to the switch for uninterrupted operation.

The switch provides an RS-232 serial port that enables a connection to a computer or terminal for monitoring and configuring the switch. This port is a male DB-9 connector, implemented as a data terminal equipment (DTE) connection.
NOTICE: CLI configuration commands only modify the running configuration file and are not saved when the switch is rebooted. To save all your configuration changes in nonvolatile storage, you must use the copy command to copy the running configuration file to the startup configuration. SNMP Settings Simple Network Management Protocol (SNMP) is a protocol designed specifically for managing devices on a network.
Before you can assign a static IP address to the switch, you must obtain the following information from your network administrator: l IP address for the switch l Default gateway for the network l Network mask for the network To assign a static IP address to the switch: 1. From the Privileged Exec level global configuration mode prompt, type interface vlan 1 to access the interface-configuration mode. Press . 2.

Back to Contents Page VLANs Dell™ PowerConnect™ 5224 Systems User's Guide VLANs and Frame Tagging VLAN Configuration Automatic VLAN Registration VLAN Examples VLANs and Frame Tagging The PowerConnect 5224 switch supports IEEE 802.1Q-compliant virtual LANs (VLANs). This capability provides a highly efficient architecture for establishing VLANs within a network and for controlling broadcast/ multicast traffic between workgroups.
belongs. Port Overlapping Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. If you implement VLANs that do not overlap but still need to communicate, you must connect them using a router or Layer 3 switch. Forwarding Tagged/Untagged Frames Ports can be assigned to multiple tagged or untagged VLANs. Each port on the switch is, therefore, capable of passing tagged or untagged frames.
VLAN Examples The following four examples demonstrate typical web-interface VLAN configurations for the switch. l Example 1 demonstrates a simple two-group VLAN setup. l Example 2 demonstrates a more elaborate setup, illustrating all possible scenarios for a comprehensive understanding of tagged VLANs. l Examples 3 and 4 show how GVRP can be used to automatically propagate VLANs across a network. Example 1 Example 1 illustrates a simple two-group VLAN setup. 1.
Example 2 Example 2 illustrates a more complicated setup and demonstrates several scenarios for configuring VLANs. 1. Set up four VLANs, as shown in following table. All switch ports remain as members of the default VLAN (VLAN ID 1). VLAN ID Name Port Members (Tagged/Untagged) 2 Admin 1 (U), 2 (U), 10 (U) 5 Internal 1 (U), 4 (U), 5 (U) 10 Web 1 (T), 9 (T), 10 (T), 11 (U), 12 (U) 15 Collocation 1 (U), 2 (U), 14 (U) 2.
Port 01: 2 Port 05: 5 Port 09: 1 Port 13: 1 Port 02: 2 Port 06: 1 Port 10: 2 Port 14: 15 Port 03: 1 Port 07: 1 Port 11: 10 Port 15: 1 Port 04: 5 Port 08: 1 Port 12: 10 Port 16: 1 The PVID of a port must be set to a VLAN ID of which the port is an untagged member. NOTE: Port 9 cannot be removed from VLAN 1 because its PVID is set to VLAN 1. 3. Return to the VLAN Membership page and remove the ports configured in this example (1, 2, 4, 5, 10, 11, 12, 14) from VLAN 1.
2. From the core switch web interface, go to the VLAN/GVRP page and ensure that GVRP Status is set to enabled. 3. For the other three switches, ensure that GVRP is enabled globally in the VLAN/GVRP page, as well as on ports connecting to the core switch in the VLAN/Port Settings page. With GVRP enabled on the core switch, GVRP advertisements for the three static VLANs are sent from all ports on the switch.
4. For each of the three wiring-closet switches, ensure that GVRP is enabled globally in the VLAN/GVRP page. 5. For each of the three wiring-closet switches, ensure that GVRP is disabled for each port in the VLAN/Port Settings page. 6. For the core switch, ensure that GVRP is enabled globally in the VLAN/GVRP page, as well as on ports connecting to the wiring-closet switches in the VLAN/Port Settings page.

In the preceding figure, the management VLAN is different on each switch, with the Layer 3 switch interconnecting the VLANs. The ports that interconnect the switches are configured as tagged ports. The ports on the Layer 3 switch that connect to the other switches must be configured as members of the management VLAN for each switch. For management VLAN access, ensure that: l You have configured the switch's management VLAN with a valid IP address, subnet mask, and default gateway.

General l Observe and follow service markings. Do not service any product except as explained in your system documentation. Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to electrical shock.
Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various peripherals or supporting hardware. CAUTION: Installing systems in a rack without the front and side stabilizers installed could cause the rack to tip over, potentially resulting in bodily injury under certain circumstances. Therefore, always install the stabilizers before installing components in the rack.
