Preface
PowerConnect 5524/5548 and PowerConnect 5524P/5548P are stackable,
advanced multi-layer devices.
This guide contains the information needed for installing, configuring, and
maintaining the device through the web-based management system, called
the OpenManage Switch Administrator.
This guide describes how to configure each system through the web-based
management system and through CLI commands.
The
CLI Reference Guide, which is available on the Documentation CD,
provides additional information about the CLI commands.

• iSCSI Optimization
• Proprietary Protocol Filtering
IP Version 6 (IPv6) Support
The device functions as an IPv6-compliant host, as well as an IPv4 host (also
known as dual stack). This enables device operation in a pure IPv6 network as
well as in a combined IPv4/IPv6 network.
For more information, see "IP Addressing" on page 209.
Stack Support
The system supports up to eight units with two fixed HDMI stacking ports.
The HDMI ports are 1.3a specification, Category 2 High Speed cables, 340
MHz (10.2 Gbit/s).
it is recommended to use HDMI cable version 1.4
The stacking feature supports the following features:
•Fast-linkfailover
• Software auto-synch.
• Improved response time to events, such as master failover
• Auto-numbering algorithm when choosing unit number
For more information, see "Stacking Overview" on page 45
Power over Ethernet
Power over Ethernet (PoE) provides power to devices over existing LAN
cabling, without updating or modifying the network infrastructure. When
PoE is used, the network devices do not have to be placed next to a power
source. PoE can be used in the following applications:
• IP Phones
• Wireless Access Points

•IPGateways
•PDAs
• Audio and video remote monitoring
For more information, see "Power over Ethernet" on page 162.
Green Ethernet
Green Ethernet, also known as Energy Efficient Ethernet (EEE), is an effort
to make networking equipment environmentally friendly, by reducing the
power usage of Ethernet connections.
The Short-Reach method, which reduces power over Ethernet cables shorter
than 40m, is supported by the device.
For more information, see "Green Ethernet Configuration" on page 391.
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 resources. To prevent HOL
blocking, the device queues packets, and packets at the head of the queue are
forwarded before packets at the end of the queue.
Flow Control Support (IEEE 802.3X)
Flow control enables lower-speed devices to communicate with higher-speed
devices, by requesting that the higher-speed device refrain from sending
packets. Transmissions are temporarily halted to prevent buffer overflows.
For more information, see "Flow Control" on page 387.
Back Pressure Support
On half-duplex links, the receiving port prevents buffer overflows by
occupying the link so that it is unavailable for additional traffic.
For more information, see "Protected Ports" on page 395.

Virtual Cable Testing (VCT)
VCT detects and reports copper link cabling faults, such as open cables and
cable shorts.
For more information, see "Diagnostics" on page 255.
Auto-Negotiation
Auto-negotiation enables the device to advertise modes of operation. The
auto-negotiation function enables an exchange of information between two
devices that share a point-to-point link segment, and automatically
configures both devices to take maximum advantage of their transmission
capabilities.
The PowerConnect 5500 series enhances auto-negotiation by providing port
advertisement. Port advertisement enables the system administrator to
configure the port speeds that are advertised.
For more information, see "Port Configuration" on page 404 or "LAG
Configuration" on page 410.
MDI/MDIX Support
Standard wiring for end stations is known as Media-Dependent Interface
(MDI), and standard wiring for hubs and switches is known as Media-
Dependent Interface with Crossover (MDIX).
If auto-negotiation is enabled, the device automatically detects whether the
cable connected to an RJ-45 port is MDIX (crossed) or MDI (straight). This
enables both types to be used interchangeably.
If auto-negotiation is not enabled, only MDI (straight) cables can be used.
For more information, see "Port Configuration" on page 404 or "LAG
Configuration" on page 410.
MAC Address Supported Features
MAC Address Capacity Support
The device supports up to 16K MAC addresses and it reserves specific MAC
addresses for system use.

Static MAC Entries
MAC entries can be manually entered in the Bridging Table, as an alternative
to learning them from incoming frames. These user-defined entries are not
subject to aging, and are preserved across resets and reboots.
For more information, see "Static Addresses" on page 425.
Self-Learning MAC Addresses
The device enables controlled MAC address learning from incoming packets.
The MAC addresses are stored in the Bridging Table.
For more information, see "Dynamic Addresses" on page 428.
Automatic Aging for MAC Addresses
MAC addresses from which no traffic is received for a given period, are aged
out. This prevents the Bridging Table from overflowing.
For more information, see "Dynamic Addresses" on page 428.
VLAN-Aware MAC-Based Switching
The device always performs VLAN-aware bridging. Classic bridging
(IEEE802.1D), in which frames are forwarded based only on their destination
MAC address, is not performed. However, a similar functionality can be
configured for untagged frames. Frames addressed to a destination MAC
address that is not associated with any port are flooded to all ports of the
relevant VLAN.
MAC Multicast Support
Multicast service is a limited Broadcast service that enables one-to-many and
many-to-many connections for information distribution. In Layer 2 Multicast
service, a single frame is addressed to a specific Multicast address, from which
copies of the frame are transmitted to the relevant ports. When Multicast
groups are statically enabled, you can set the destination port of registered
groups, as well as define the behavior of unregistered Multicast frames.
For more information, see "Multicast" on page 517.
