Introduction 11 Introduction Dell™ P o werConnect™ 3524/3548 and P owerC onnect 3524P/3548P are stackable, advanced multi-layer devices. P o werConnect units can functio n either as stand-alone, multi-layer , switching devices or stackable devices with up to eight stacking members.
12 Introduction PowerConnect 3548 The P owerConnect 3548 provides 48 10/100Mbps ports p lus two SFP ports, and two Copper ports which can be used to forward traffic in a stand-alone devi ce, or as stacking ports when the device is stack ed. The device also provides one RS-232 console port.
Introduction 13 Understanding the Stack T opology The P owerConnect 35xx series systems operates in a R ing topology . A stacked Ring topology is wher e all devices in the stack are connected to each other formin g a circle. Each device in the stack accepts data and sends it to the device to which it is attached.
14 Introduction The device units are shipped with a default Unit ID of the stand-alone unit. If t he device is operating as a stand-alone unit, all stacking LEDs are off. Once the user selects a different Unit ID, it is not erased, and remains valid, even if the unit is r eset.
Introduction 15 Each port in the stack has a specific Unit ID, port type, and port num ber , which are part of both the configuration commands and the configuration files.
16 Introduction Figure 1-4. PowerConnect 3548/P replaces PowerC onnect 3548/P • If a P owerConnect 3548/P replaces P owerConnect 3524/P , the first 3548/P 24 FE ports r eceive the 3524/P 24 FE port configuration. Th e GE port configurations rema in the same.
Introduction 17 Figure 1-6. PowerConnect 3548/P port replaces PowerConect 3524/P Port Switching from the Stack Master to the Backup Stack Master The Backup Master replaces the Stack Master if the following events occur: • The Stack Master fails or is removed from the stack.
18 Introduction •P D A s • Audio and video r emote monitoring F or more information about P ower over Et hernet, see "Managing P ower over Ethernet". Head of Line Blocking Prevention Head of Line (HOL) blocking results in traffic delays and frame loss caused by traffic competing for the same egress port r esources.
Introduction 19 The P owerConnect 35xx series systems enhances auto negotiation by providing port advertisement. P ort advertisement allows the system administrator to configure the port speeds that ar e advertised. F or more information on auto-negotiation, see "Definin g P ort Configuration" or "Defining LAG P arameters.
20 Introduction VLAN-aware MAC-based Switching The device always performs VLAN-aware bridging. Classic bridging(IEEE802.1D) is not performed, where frames ar e forwarded based only on their destination MAC addr ess. However , a similar functionality can be configured for untagged frames .
Introduction 21 VLAN Supported Features VLAN Support VLANs are collections of switching ports that comprise a single broadcast domain. P ackets ar e classified as belonging to a VLAN based on either the VLAN ta g or based on a combination of the ingress port and packet contents.
22 Introduction Fast Link STP can take up to 30-60 seconds to conver ge. Durin g this time, STP detects possible loops, allowing time for status changes to propagate and for relevant devices to r espond. 30-60 seconds is considered too long of a response time for many applications.
Introduction 23 BootP and DHCP Clients DHCP enables additional setup para meters to be r eceived from a network server upon system startup. DHCP service is an on-going process. DHCP is an extension to BootP . F or more information on DHCP , see "Def ining DHCP IPv4 Interface P arameters.
24 Introduction TF TP T rivial File T ransfer Protocol The device supports boot image, software, an d configuration upload/download via TFTP . Remote Monitoring Remote Monitoring (RMON) is an extensio.
Introduction 25 802.1ab (LLDP-MED) The Link Layer Discovery P rotocol (LLDP) allows network managers to troubleshoot and enhance network management by discovering and mainta ining network topologies over multi-vendor environments.
26 Introduction SSH Secure Shell (SSH) is a protocol that provides a secur e, remote connection to a device. SSH version 2 is currently supported. The SSH serv er featur e enables an SSH client to establish a secure, encrypted connection with a device.
Hardware Description 27 Hardware Description Port Description PowerConnect 3524 Port Description The Dell™ P owerConnect™ 3524 device is configured with the following ports: • 24 F ast Ethernet .

34 Hardware Description The following table describes the system LED indications. The Stacking LEDs indicate the unit po sition in the stack. The following figure illustrates the LEDs on the front panel. Figure 2-10. Stacking LEDs T able 2-5. Sy stem LED Indicators LED Color Description P ower Supply (PWR) Gr een Static The switch is turned on.
Hardware Description 35 The Stacking LEDs are number ed 1- 8. Each stacking unit has one stacking LED lit, indicating its Unit ID number . If either Stacking LED 1 or 2 is lit, it in dicates that the device is either the Stack Master or Backup Master .
36 Hardware Description Figure 2-11. Power Connection When the device is connected to a di fferent power source, the probabil ity of failure in the event of a power outage decreases. Stack ID Button The device front panel contains a Stack ID button us ed to manually select t he Unit ID for the Stack Master and members.
Hardware Description 37 Reset Button The P owerConnect 3524/P and P owerC onnect 3548/P switches have a rese t button, located on the front panel, for manual reset of the device. If the Master de vice is r eset, the entire stack is r eset. If only a member unit is reset, the r emain stacking members are not reset.
