  • Appliance: 1U of rack space and 2x495W of power

  • Network Access: Four 10/100/1000 BASE-T network ports and two 10G BASE-SR ports

EH9100

  • Appliance: 2U of rack space and 2x750W of power

  • Network Access: Four 10/100/1000 BASE-T network ports and four 10G BASE-SR ports

You can access the ExtraHop graphical user interface from any web browser that supports the Adobe Flash Player 9 plug-in, available for download from www.adobe.com/products/flashplayer/.

Install the ExtraHop Appliance

To install the ExtraHop appliance, complete the following steps.

  1. Rack Mount the ExtraHop Appliance: Install the ExtraHop appliance in your datacenter using the included rack-mounting kit, which supports most four-post racks with either round or square holes.

  2. Connect Port 1: The ExtraHop appliance contains four 10/100/1000 BASE-T network ports and uses port 1 to administer the system. Use a network patch cable to connect the Gb1 port on the ExtraHop appliance to the management network.

Acquire an IP Address

You can acquire an IP address automatically or choose to configure a static IP address. The ExtraHop system displays the assigned IP address on the LCD at the front of the appliance.

Automatically Acquired IP Address: DHCP is enabled by default on the ExtraHop appliance, so when you power on the system, interface 1 attempts to acquire an IP address using DHCP. After the DHCP server assigns an IP address, the ExtraHop system displays it on the LCD at the front of the appliance.

Static IP Address (CLI): If your network does not support DHCP, you can use the ExtraHop web administration utility or the command line interface (CLI) to configure a static IP address. You can access the CLI from a USB keyboard and SVGA monitor or by using an RS-232 serial cable and a terminal-emulator program. The terminal emulator must be set to 115200 bps with 8 data bits, no parity, and 1 stop bit (8N1). Hardware flow control should be disabled.

Refer to the following table for RS-232 serial cable pin assignments.

Signal Name DB-9 Pin
(Server Pin)
DB-9 Pin
(Workstation Pin)
FG (Frame Ground) - -
TD (Transmit Data) 3 2
RD (Receive Data) 2 3
RTS (Request to Send) 7 8
CTS (Clear to Send) 8 7
SG (Signal Ground) 5 5
DSR (Data Set Ready) 6 4
CD (Carrier Detect) 1 4
DTR (Data Terminal Ready) 4 1 and 6

In the CLI, complete the following steps to set the IP address:

  1. Log in to the console with the shell user account. The password is the service tag number on the pullout tab on the front of the appliance.

  2. Enable the privilege commands.

    extrahop>enable

    Password:

    extrahop#

  3. Enter the configuration section.

    extrahop#config

    extrahop(config)#

  4. Enter the interface section.

    extrahop(config)#interface

    extrahop(config-if)#

  5. Set the IP address and DNS using this syntax: ip ipaddr IP_ADDRESS NETMASK GATEWAY DNS_SERVER

    extrahop(config-if)#ip ipaddr 10.10.2.14 255.255.0.0 10.10.1.253 10.10.1.254

    extrahop(config-if)#ip dnsservers 10.10.1.254 10.10.2.254

  6. Save the running config.

    extrahop(config-if)#exit

    extrahop(config) * #running_config save

    Would you like to write configuration changes to default config [Y/n]?: y

    extrahop(config)#

    The full set of commands is as follows:

    extrahop>enable

    Password:

    extrahop#configure

    extrahop(config)#interface

    extrahop(config-if)#ip ipaddr <addr> <netmask> <gateway>

    <dns>

    Changing IP address. Please wait...

    .Done

    extrahop(config-if)#exit

    extrahop(config) * #running_config save

    Would you like to write configuration changes to default config [Y/n]?: y

    extrahop(config)#exit

    extrahop#

    After you assign a static IP address, the ExtraHop system displays it on the LCD at the front of the appliance.

Static IP Address (LCD): When the appliance is running, the LCD displays the existing IP.

If an IP address hasn’t been configured, the LCD displays No IP. Complete the following steps to configure the IP address.

  1. Press the Select (checkmark) button. Navigate using the left and right arrow buttons. Select Net.

  2. Select Host.

    The screen displays the host name. Return to the previous screen by scrolling to the up arrow on the screen and selecting it.

  3. Select DHCP to see how the IP address is configured. Use left and right arrow buttons to select an option, and press the Select button.

  4. On the Net screen, select IP and use the left and right arrow buttons to move between the digits. On the selected digit, click the Select button. The digit blinks when selected. While the digit is blinking, use the left and right arrow buttons to change the digit value.

    Note: Setting a static IP address may require several attempts. If the static IP address fails to save on the first attempt, set a temporary static IP address and then set the desired static IP address.

  5. Once you have entered the number, click Select to once again use the left arrow button to navigate to the up arrow on the screen and select it. On the Save screen, select Yes.

  6. Wait to be redirected to the Net screen. Repeat these steps to set the mask, gateway, and up to two DNS servers.

  7. Use the arrow keys to scroll back to the Home menu and select iDRAC. Configure the iDRAC DHCP, IP, mask, gateway, and DHCP in the same manner as the IP.

  8. On the Net screen, select Errors to view system events such as CPU errors, undetected hard drives, or missing power supplies. When an error occurs, the LCD turns amber and displays the error immediately.

  9. If there are multiple errors, use the left and right arrow buttons to scroll between the error messages. Press the Select button to exit the error screen. The Clear option removes the list of messages from the error screen.

  10. When the system is not running, the LCD screen displays ExtraHop.

Configure the System Time

The default time server setting is pool.ntp.org. If you want to use the default setting, go to the next section.

You can configure the system time manually in the CLI. The login is shell and the password is the service tag number on the pullout tab on the front of the appliance. Type enable and enter the same password when prompted.

extrahop>enable

extrahop#configure

extrahop(config)#time Jan 1 2009 00:00:00

extrahop(config)#exit
