6 Aruba 2930M Switches

Chapter 1

Introducing the 2930M switches

Aruba 2930M multiport switches can be used to build high-performance switched networks. These switches are store-and-forward devices offering low latency for high-speed networking. The 2930M switches also support a field-replaceable redundant power supply, Power over Ethernet (PoE/PoE+) technologies, full network management capabilities, a stacking module slot, and a flexible uplink port slot.

When 2930M stacking modules are installed in the switches, any combination of up to ten 2930M switches can be stacked together via high-speed backplane cables to form a single extended virtual switch. See Stacking information and topologies and the HPE ArubaOS-Switch Advanced Traffic Management Guide for your switch OS version for more stacking information.

These switches are described in this manual:

Management ports

Console Ports

There are two serial console port options on the switch: an RJ-45 or Micro USB. These ports are used to connect a console to the switch either by using an Aruba X2C2 RJ45 to DB9 Console Cable (JL448A) (sold separately) or a standard Micro USB cable (not supplied). The Micro USB connector has precedence for input. If both cables are plugged in, the console output is echoed to both the RJ-45 and the Micro-USB ports, but the input is only accepted from the Micro-USB port.

For more information on the console connection, see Setting up a console connection. The console can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.

USB Console Port driver download: When using the Micro USB Console Port, the connected PC first requires “virtual COM port” USB drivers to be installed. USB console drivers are available at www.hpe.com/networking/support. Type a product name (for example, 2930M) or product number in the Auto Search textbox. Select one of the switches from the drop-down list. Click the Display selected button. From the options that appear, select Software downloads (on the right side of the window). Download USB Console Port Drivers and Information.

User Mode Selected

Mode currently active only in stacked configurations.

Used to display the number of members in a stack and their current status.

The status information is sticky and if a unit’s status changes while in USER mode, you must exit and re-enter USER mode to get the updated status.

On Green Stack Member exists in

the stack and is operational.

Slow Flash Green* Indicates the Member # of

the chassis.

Fast Flash Green** Indicates the Member # of

the Commander of the stack.

On Orange Stack Member is currently

booting or has a fault that is preventing it from communicating.

Slow Flash Orange*

Fast Flash Orange**

Stack Member is in a known fault condition (for example, a PSU fault).

The Global Status LED on all stack members will also Slow Flash Orange.

Stack Member is in a Alert condition (i.e. Overtemp, PoE Over subscript, etc.).

The Global Status LEDs on all stack members will remain in normal operational.

Off Stack Member does not

exist in the stack configuration.

* The slow blink behavior is an on/off cycle once every 1.6 seconds, approximately.

** The fast blink behavior is an on/off cycle once every 0.5 seconds, approximately.

*** Applies only to switches that support PoE/PoE+.

Example of USER mode behavior

Assume you have a 4-member stack, in a ring topology, with member numbers 1, 2, 3 and 5. Member 1 is the commander and member 3 is rebooting. In USER mode, the members will show the following on their port LEDs:

Chapter 1 Introducing the 2930M switches 17

Port 1 LED Port 2 LED Port 3 LED Port 4 LED Port 5 LED Port 6-10

LEDs

Member 1 Fast Flash

Green

Member 2 Fast Flash

Green

Member 3 Going through normal boot up sequencing

Member 5 Fast Flash

Green

Looking at any member, you can see that there are 4 members defined in the stack configuration, with member numbers 1, 2, 3, and 5 because these are the LEDs that are lit. The port 4 LED is off, indicating that this member number is not defined in the stack.

On all members, Port 1 LED is fast flashing, indicating that member 1 is the commander of the stack. Port 3 LED is on orange, indicating either that 3 is rebooting or not communicating because of an unknown fault.

When looking at member 1, only Port 1 LED is fast flashing green. This indicates that this unit is member 1 and is the commander.

When looking at member 2, the port 2 LED is slow flashing green, indicating that unit is member number 2. Likewise on member 5, the port 5 LED is slow flashing green, indicating that unit is member 5.

Member 3 will be going through the normal boot LED boot up sequence. When it has completed booting and joined the stack, if you exit and re-enter USER mode, the members show the following on their port LEDs:

Stacking Notes

• For 2930M switches that are in a stack, the LED Mode select button on every switch in the stack controls the LED mode for all the switches in the stack. Using the LED Mode select button on one switch in the stack changes the LED mode for the entire stack.

• If there is a combination of PoE/PoE+ switches and non-PoE switches in the stack, when any of the LED Mode select buttons is pressed to put the stack into PoE mode, the non-PoE switches indicate no PoE support by not illuminating any of the mode indicator LEDs or any of the port LEDs.

• If any of the switches in the stack are configured with the Save Power LED feature, the default LED mode for the whole stack becomes the Save Power display (all LED mode indicator LEDs are off), but only the stack members on which that feature is configured display the other characteristics of that feature (all LEDs off except for the power LED).

Reset and Clear buttons

The Reset and Clear buttons are recessed from the front panel (to protect them from being pushed accidentally) and are accessible through small holes on the top of the front panel. Use pointed objects, such as unbent paper clips, to push them.

The buttons are used singly or in combination, as follows:

To accomplish this: Do this: This will happen:

Soft reset (Standalone switch) Press and release the Reset button The switch operating system is

cleared gracefully (such as data transfer completion, temporary error conditions are cleared), then reboots and runs self-tests.

Hard reset (Standalone switch) Press and hold the Reset button for

more than 5 seconds (until all LEDs turn on), then release.

Soft reset (Stacked switch) Press and release the Reset button Same as a standalone switch,

Hard reset (Stacked switch) Press and hold the Reset button for

more than 5 seconds (until all LEDs turn on), then release.

The switch reboots, similar to a power cycle. A hard reset is used, for example, when the switch CPU is in an unknown state or not responding.

except:

• If action happened on the commander, the standby switch will become commander.

• If action happened on the standby, a new standby will be elected.

Same as a standalone switch, except:

The switch removes all configuration changes, restores the factory default configuration, and runs self test.

Out-of-band management (OOBM) port

This RJ-45 port is used to connect a dedicated management network to the switch. To use it, connect an RJ-45 network cable to the management port to manage the switch through Telnet from a remote PC or a UNIX workstation.

To use this port, the switch must have an IP address. IP settings can be configured through a console port connection or automatically from a DHCP/Bootp server.

A networked out-of-band connection through the management port allows you to manage data network switches from a physically and logically separate management network.

For more information, see the Network Out-of-Band Management (OOBM) appendix in the Management and

Configuration Guide at www.hpe.com/networking/support.

Power supplies

The following power supplies can be installed in the 2930M switches:

• Aruba X371 12VDC 250W 100-240VAC Power Supply (JL085A): A 250 watt power supply for the non-PoE switches. This power supply does not provide any PoE power, and is keyed so that it will not fit into the power supply slots of 2930M PoE+ switches.

• Aruba X372 54VDC 680W 100-240VAC Power Supply (JL086A): A 680 watt power supply for 2930M PoE+ supported switches. This power supply offers up to 370 watts of PoE+ power, and is keyed so that it does not fit into the power supply slots of non-PoE+ 2930M switches.

• Aruba X372 54VDC 1050W 110-240VAC Power Supply (JL087A): A 1050 watt power supply for 2930M PoE + supported switches. This power supply offers up to 740 watts of PoE+ power, and is keyed so that it does not fit into the power supply slots of non-PoE+ 2930M switches.

For initial power supply installation, refer to the Aruba 3810M/2930M Switch Power Supply Quick Setup Guide and Safety/Regulatory Information that was shipped with the power supply units.

For more power supply information, see (Optional) Installing a second power supply.

Power connector

The 2930M switches do not have a power switch. They will power on when either one or both power supplies are connected to an active AC power source.

Stacking module slot

Each of the 2930M switches has one module slot that can accept the following:

• 2930M Stacking Module (JL325A)

• 2920/2930M 0.5m Stacking Cable (J9734A)

• 2920/2930M 1.0m Stacking Cable (J9735A)

• 2920/2930M 3.0m Stacking Cable (J9736A)

These components provide high-speed connectivity to other 2930M switches. Only the 2930M switches support this module.

Uplink port slot and module support

The 2930M family of switches features a module slot that allows the user to customize the uplink ports on the switch. The slot support 40Gbps of maximum bandwidth and is available in three possible options: 4 Smart Rate, 4 SFP+, or 1 QSFP+.

Unsupported modules are mechanically prevented from installing into unsupported slots.

LEDs on the back of the switches

This section describes the LEDs on the back of the switch. When the back LED on the front of the unit is blinking a fault, the user can look at the back of the switch to find the corresponding blinking LED for the faulted module or power supply. If a user installs a second power supply and did not turn on the power (PSU module status = OFF), the back LED will blink orange.
