Install a network-attached HSM into a rack

This guide covers the following HSMs:

  • nShield Connect

  • nShield 5c

Always handle modules correctly. Take due account of the weight and dimensions of the HSM when selecting a location for storage or installation. For more information, see Handling an HSM.
You cannot install or configure the HSM remotely.

To install the HSM in a 19” rack, follow the instructions supplied with your rack mounting kit.

To install the HSM in a cabinet or a shelf, fit the four self-adhesive rubber feet (supplied with the HSM) to the bottom of the HSM. An X is scored into the chassis at each of the four corners on the bottom of the HSM as a guide to placing the feet.

If you encounter any problems during the install process, refer to Troubleshooting. This page includes explanations for the status LED, log messages, and audible warnings as well as other information.

Connecting Ethernet, console and power cables

The HSM is an Ethernet network device capable of supporting up to 100m of Ethernet cable. You must use a CAT5e UTP cable or better when connecting the HSM to a 100Mbit or 1Gbit Ethernet device. You must use a CAT3 cable or better for 10Mbit connections.

The connectors for Ethernet cables and mains power cables are at the rear of the HSM.

Ensure that:

  • All power cables are routed to avoid sharp bends, hot surfaces, pinches, and abrasion.

  • You connect mains power cables to both the PSUs.

  • The rocker switch for each PSU is in the on position.

The following image shows the Ethernet, console and mains power connections:

RJ45 port for a serial console cable

If you connect only one Ethernet cable to the HSM, Entrust recommends that you connect it to Ethernet port 1. This is the left-hand Ethernet connector on the rear of the HSM (shaded in the image).

If the green LED is on, the PSU is operational and receiving power, and is not in Standby mode. If a power cable is not fitted correctly, or a rocker switch is not turned on, an audible warning is given and the orange warning LED on the front panel is turned on.

For more information:

  • Audible warnings, see Audible warning.

  • The orange warning LED, see Orange warning LED.

  • Identifying and replacing a faulty PSU, see the HSM Power Supply Unit Installation Sheet.

Connecting the Serial Console

On supported HSM hardware variants (see Model numbers) there is a serial console port that provides access to a serial console command line interface that enables remote configuration of the HSM (See the HSM User Guide).

The RJ45 connector for the serial cable is at the rear of the HSM and is labelled Console, see Connecting Ethernet, console and power cables. The connector can be directly connected to your client machine or connected to a serial port aggregator for remote access. For a specification of the serial cable required, see Serial Console cable pinout information. The serial port will operate at 9600 baud, 8 data bits, no parity, and 1 stop bit (9600/8-N-1).

It is recommended to use a shielded cable for the serial connection as the EMI noise from other devices in vicinity may affect the communication over the serial connection.

Serial Console cable pinout information

Connecting the optional USB keyboard

Connecting the optional USB keyboard

Instead of using the controls on the front panel to configure the HSM, you can use a US or UK keyboard. You might find a keyboard easier for entering dates and IP addresses. You connect the keyboard to the USB connector on the front of the HSM.

Configuring an HSM for your keyboard type

To configure an HSM for your keyboard type, select System > System configuration > Keyboard layout and then choose the keyboard type you require.

When you have connected a keyboard and configured the HSM for its use, you can enter numbers and characters directly into the display. See the HSM User Guide for more about using a keyboard and keystroke shortcuts.

Checking the installation

Ensure that:

  • The HSM is safely and securely installed.

  • The mains cables and Ethernet cable are securely fitted.

  • The HSM powers up successfully when you turn on the power supply at the rear of the HSM.
