Introducing the Switch
The HP ProCurve Series 6600 Switches are top-of-rack data center switches
that support advanced Layer three switching, and have reversible front-to-
back airflow, and two hot-swappable power supplies. These switches can be
used to build high-speed switched networks between servers in the data
center.
Throughout this manual, these switches will be referred to as the Series 6600
Switches.

Introducing the Switch
The 6600-24G Switch has 20 auto-sensing 10/100/1000Base-T RJ-45 ports, four
dual-personality ports—either auto-sensing 10/100/1000Base-T RJ-45 or mini-
GBIC (Small Form-Factor Pluggable (SFP)) ports.
The 6600-24G-4XG Switch has the same ports as the Switch 6600-24G plus it
also has 4 SFP+ slots for 10-GbE connectivity. The specification for SFP+
defines the physical and electrical characteristics of this form-factor (size and
shape). The form-factor is identical to SFP, but the SFP+ is a 10-Gigabit
Ethernet transceiver.
The 6600-24XG Switch has 24 SFP+ slots. All slots are 10-GbE.
Table 1-1. These products support optional network connectivity with the
following speeds and technologies:

Introducing the Switch
Introducing the Switch
These switches are designed to be used primarily in data center environments
mounted in equipment racks along with the servers they are connected to.
These switches can directly connect servers to other servers or backbone
LANs to provide dedicated bandwidth to those devices, and can build a
switched network infrastructure by connecting the switch to hubs, other
switches, or routers. In addition, the Series 6600 Switches offer full network
management capabilities.
This chapter describes the Series 6600 Switches, including:

Network Ports
■On the 6600-24G and 6600-24G-4XG Switches there are 24 auto-sensing
10/100/1000Base-T ports. All these ports have the “Auto MDIX” feature,
which means you can use either straight-through or crossover twisted-
pair cables to connect any network devices to the switch.
■On the 6600-24G and 6600-24G-4XG Switches there are four dual-person-
ality ports. Use either the 10/100/1000Base-T RJ-45 connector, or install a
supported ProCurve mini-GBIC for fiber-optic connections.
Dual-Personality Port Operation. By default, the RJ-45 connectors are
enabled. If a mini-GBIC is installed in a slot, it is enabled and the associ-
ated RJ-45 connector is disabled and cannot be used. If the mini-GBIC is
removed, the associated RJ-45 port is automatically re-enabled.
■On the 6600-24XG Switch there are 24 SFP+ 10-GbE ports. SFP+ ports
only support 10 Gbps operation; 1 Gbps mini-GBICs are not supported in
any SFP+ port.

defined groups of ports to save power through the use of a CLI command,
“savepower”. This feature provides the capability to explicitly power down
the ports, including the LEDs, for a group of un-used ports associated with a
block number.
This is only a temporary setting. The command is not retained after a power
cycle or reboot. For more information regarding this feature see the Manage-
ment and Configuration Guide which is on the ProCurve Web site at
www.procurve.com/manuals.
LED Mode Select Button and Indicator LEDs
The operation of the Mode LED is controlled by the LED Mode select button,
and the current setting is indicated by the LED Mode indicator LEDs near the
button. Press the button to step from one view mode to the next.

■Each port has a Link LED. If it is lit, the port has a link. If the Link LED is
Blinking, the port has failed its self test. The Fault and Self Test LEDs will
be Blinking simultaneously.
■If the Activity (Act) indicator LED is lit, each port LED displays activity
information for the associated port—it flickers as network traffic is
received and transmitted through the port.
■If the Full Duplex (FDx) indicator LED is lit, the port LEDs light for those
ports that are operating in full duplex.
■If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows
to indicate the connection speed for the port:
• Off = 10 Mbps
• Blinking = 100 Mbps (the Blinking behavior is a repeated on/off cycle
once every 0.8 sec.)
• On = 1000 Mbps
■The Usr Mode LED indicates the port is displaying customer-specified
information.
Reset Button
This button is for:
■Resetting the switch - When the switch is powered on. This action clears
any temporary error conditions that may have occurred and executes the
switch self test.
■Restoring Factory Default Configuration - When pressed with the
Clear button in a specific pattern, any configuration changes you may have
made through the switch console, the web browser interface, and SNMP
management are removed, and the factory default configuration is
restored to the switch. For the specific method to restore the factory
default configuration, see “Restoring the Factory Default Configuration”
on page 11, in the Troubleshooting chapter of this manual.

This button is used for:
■Deleting Passwords - When pressed by itself for at least one second, the
button deletes any switch console access passwords that you may have
configured. Use this feature if you have misplaced the password and need
console access. This button is provided as a convenience, however if you
are concerned with thesecurity of the switch configuration and operation,
you should make sure the switch is installed in a secure location. This
button can be disabled by a CLI command.
■Restoring Factory Default Configuration - See Reset Button above.
Console Port
This port is used to connect a console to the switch either by using the RJ-45
to DB9 cable or the DB9 to DB9 serial cable supplied with the switch. The
Series 6600-24G and 6600-24G-4XG Switches use the DB9 to DB9 serial cable
and the 6600-24XG Switch uses the RJ-45 to DB cable. This connection is
described under “Connect a Console to the Switch” in chapter 2, “Installing
the Switch.”The console can be aPC or workstation running a VT-100 terminal
emulator, or a VT-100 terminal.

Power Connector
The Series 6600 Switches do not have a power switch; they are powered on
when connected to an active AC power source. These switches automatically
adjust to any voltage between 100--127 and 200--240 volts and either 50 or 60
Hz. There are no voltage range settings required.
Switch Features
The features of the Series 6600 Switches include:
■24 auto-sensing 10/100/1000Base-T RJ-45 ports with Auto-MDIX or 24
SFP+ 10-GbE ports. The 6600-24G-4XG has only 4 SFP+ 10-GbE ports.
■Four dual-personality ports—either the auto sensing 10/100/1000Base-T
RJ-45 or the mini-GBIC can be used for each port. The 6600-24XG does
not have these dual-personality ports.
■An auxiliary (USB) port for processing a USB command file.
■Plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational.

Switch Features
Introducing the Switch
■The 6600-24G and the 6600-24G-4XG supports IEEE 802.3ab Auto MDIX
on all 10/100/1000 twisted-pair ports, meaning that all connections can
be made using straight-through twisted-pair cables. Cross-over
cables are not required, although they will also work. The pin operation
of each port is automatically adjusted for the attached device: if the switch
detects that another switch or hub is connected to the port, it configures
the port as MDI; if the switch detects that an end-node device is connected
to the port, it configures the port as MDI-X.
■Automatic learning of the network addresses in each switch’s 8000-
address forwarding table, (with configurable address aging value).
■Automatically negotiated full-duplex operation for the 10/100/1000 RJ-45
ports when connected to other auto-negotiating devices—the mini-GBIC
ports always operate at full duplex.
■Easy management of the switch through several available interfaces:
•console interface—a full featured, easy to use, VT-100 terminal
interface that is especially good for out-of-band switch management
or for Telnet access to the switch.
•web browser interface—an easy to use built-in graphical interface
that can be accessed from common web browsers.
•ProCurve Manager—an SNMP-based, graphical network manage-
ment tool that you can use to manage your entire network. This
product is included with your new switch.
■Support for the Spanning Tree Protocol to eliminate network loops
■Support for up to 2048 IEEE 802.1Q-compliant VLANs so you can divide
the attached end nodes into logical groupings that fit your business needs.
■Support for many advanced features to enhance network performance—
for a description, see the Management and Configuration Guide, which
is on the ProCurve Web site www.procurve.com/manuals.
■Download of new switch software for product enhancements or bug fixes.
