LCD module

The front panel has an LCD module that includes an LCD and five menu buttons. The LCD provides information about the appliance. The menu buttons are not functional.

Locate LED

The appliance has a locate LED to help you easily identify the intended appliance.

From the Web UI
  1. In the search field, enter system.
  2. From the results, click System Control.
  3. Locate the Control Locate LED section.
    • To activate, enable.
    • To deactivate, disable.
  4. Click Control Locate LED.
From the CLI
Use the Global locate-device command.
  • To activate, enter locate-device on.
  • To deactivate, enter locate-device off.

Power button

The power button is on the front of the appliance.

When the appliance is powered off, press the button to turn it on.

When the appliance is powered on, press the button to start a graceful shutdown.

Console port

The front has a console port for serial communications. The console port receives an RJ45 jack from either of the supplied serial console cables.

For initial configuration, use one of the supplied serial cables to for the following connection.

  • To connect from a PC that is running terminal-emulation software to the appliance.
  • To connect from an ASCII terminal to the appliance. An ASCII terminal is a simple device that transmits and receives ASCII data.

USB ports

The appliance has two USB ports that conform to USB 3.0 devices. The USB ports are not active. Therefore, they do not provide any connection.

Network ports

The network ports transmit and receive data communications between the appliance and external sources.

Network ports are grouped and located by function.
  • Two fixed management Ethernet ports.
  • One removable 1 Gb Ethernet module with eight ports for the RJ45 interface.
  • One removable 10 Gb Ethernet module with four SFP+ ports.
  • Two removable 40 Gb Ethernet modules, each with two QSFP+ ports.
  • One removable 100 Gb Ethernet module with two QSFP28 ports.

Management Ethernet ports

The management Ethernet ports provide remote management access to the appliance and should not be used as data ports. Use the ports in the Ethernet modules for handling data traffic.

Consider management traffic in the overall availability, network, and management plan for the deployment. Management traffic, with the exception of IPMI, is not fundamentally different than any other kind of traffic the appliance processes. The same techniques that separate network zones apply equally to management traffic.

mgt0
This Ethernet interface can manage all management data. This port also supports IPMI over LAN, which includes serial over LAN.
mgt1
This Ethernet interface can manage all management data. This port also supports IPMI over LAN, which includes serial over LAN.

Ethernet modules

The appliance has three Ethernet modules for network connectivity. The right module contains eight 1 Gb Ethernet ports. The middle modules contain four 40 Gb Ethernet ports. The left module contains four 10 Gb Ethernet ports.

1 Gb Ethernet module
Has eight RJ45 Ethernet ports. The Ethernet ports are placed in two rows. The numbering start with 10 and are sequential from lower-left to upper-right. Each port has an associated speed LED and activity LED. The speed and activity LEDs on the lower and upper rows have opposite orientation.

10 Gb Ethernet module
Has four 10 Gb SFP+ ports. The numbering start with 20 and are sequential from left to right. Each port has an associated activity LED. By default, eth20 is used for the replication link in a disaster recovery configuration and eth21 is used for the replication link in a high availability configuration.

40 Gb Ethernet modules
Has two 2 x 40 Gb QSFP+ ports. They are numbered 30, 31, 32, 33 respectively. Each port has an associated activity LED.
40 Gb Ethernet module port

Activity LED for eth30
Each 40 Gb Network module provides a total of 40Gb of bandwidth that is shared between the two physical ports on that module. You can create an aggregate interface using one physical connection to each network module (for example, eth30 and eth32) to boost total bandwidth and the availability characteristics of the link.
100 Gb Ethernet module
Has two 2 x 100 Gb QSFP28 ports. They are numbered 40 and 41 respectively. Each port has an associated activity LED and speed LED.

Solid-state disk drive modules

The M2003 appliance has four solid-state disk drive modules.

Fan modules

The appliance has three fan modules. Each fan module contains a cooling fan with an LED that indicates the status of the module.

  • Single flash when power is first applied.
  • Steady when the fan is operating at less than 1200 RPM or when there is a fault.
  • No illumination when operating normally or when no power is present.

The speed of the fans is responsive to the temperature of the appliance as measured by internal sensors. As the temperature changes, the fan speed changes to compensate.

Power supply modules

The appliance is powered by two redundant power supply modules.

DANGER
Multiple power cords. The product might be equipped with multiple power cords. To remove all hazardous voltages, disconnect all power cords. (L003)

A single power supply module can supply the power to support appliance operations. Each power supply module contains an LED that indicates the status of the module.

  • Steady green indicates that the module is connected to a power source.
  • Steady red indicates that the module is not functioning within design specifications.
  • Not illuminated indicates that there is no power to the module.
