This guide explains how to install the rack-mounted ExtraHop EH3000, EH6000, and EH8000 Discover
appliances.
System requirements
The ExtraHop system uses the rack-mounted ExtraHop Discover appliance in conjunction with a browser-
based graphical user interface. Installation of the Discover appliance has the following requirements:
EH3000
Appliance
1U of rack space and 495W of power
Network Access
Four 10/100/1000 BASE-T network ports
EH6000
Appliance
1U of rack space and 495W of power
Network Access
Four 10/100/1000 BASE-T network ports and two 10G BASE-SR ports
EH8000
Appliance
2U of rack space and 750W of power
Network Access
Four 10/100/1000 BASE-T network ports and two 10G BASE-SR ports
Install the Discover appliance
To install the Discover appliance, complete the following steps.
1. Rack Mount the Discover appliance
Install the Discover appliance in your data center using the included rack-mounting kit, which supports
most four-post racks with either round or square holes.
2. Connect Port 1
The Discover appliance contains four 10/100/1000 BASE-T network ports and uses the Gb1 port to
administer the system. Use a network patch cable to connect the Gb1 port on the Discover appliance
to the management network.
Configure an IP address
DHCP is enabled by default on the ExtraHop appliance. When you power on the appliance, interface 1
attempts to acquire an IP address through DHCP. If successful, the IP address appears on the home
screen of the LCD. If an IP address has not been configured, the LCD displays No IP.

If your network does not support DHCP, you can configure a static IP address through the LCD menu on
the front panel or through the command-line interface (CLI).
Configure an IP address (CLI)
1. Establish a connection to the ExtraHop appliance.
2. At the login prompt, type shell and then press ENTER.
3. At the password prompt, type the service tag number found on the pullout tab on the front of the
appliance, and then press ENTER.
4. Enable the privilege commands.
extrahop>enable
Password:
extrahop#
5. Enter the configuration section.
extrahop#config
extrahop(config)#
6. Enter the interface section.
extrahop(config)#interface
extrahop(config-if)#
7. 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
8. 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)#
After you assign a static IP address, the IP address appears on the LCD at the front of the appliance.
Configure a static IP address through the front panel
Complete the following steps to manually configure an IP address through the front panel LCD controls.
1. Make sure that the default management interface is connected to the network and the link status is
active.
2. Press the select button (#) to begin.
3. Press the right arrow (>) button to select Net and then press the select button.
4. Press the right arrow button twice to highlight DHCP and then press the select button.
5. Press the right arrow button to select Static and then press the select button.
6. Press the right arrow button to select IP and then press the select button. The currently configured IP
address appears.
7. Press the right arrow button until the first digit you want to change is highlighted.
8. Press the select button. The digit blinks when selected. While the digit is blinking, press the left arrow
(<) or right arrow (>) button to change the digit value.
9. After you have chosen the correct digit, press the select button.

address.
Configure the system time
The default time server setting is pool.ntp.org. If you want to maintain the default setting, skip this
procedure and go to the next section.
1. In the Appliance Settings section, click System Time.
2. Click Configure Time.
3. Click the Time Zone drop-down list and select a time zone.
4. Click Save and Continue.
5. On the Time Setup page, select one of the following options:
• Set time manually
Note: You cannot manually set the time if the Discover appliance is managed by a
Command appliance.
• Set time with NTP server
6. Select the Set time with NTP server radio button, then click Select.
The pool.ntp.org public time server appears in the Time Server #1 field by default.
7. Type the IP address or fully qualified domain name (FQDN) for the time servers in the Time Server
fields. You can add a maximum of nine time servers.
Tip: After adding the fifth time server, click Add Server to display up to four additional time
server fields.
8. Click Save, and then click Done.
The NTP Status table displays a list of NTP servers that keep the system clock in sync. To sync the current
system time a remote server, click the Sync Now button.
Connect the monitoring port

Enable the 10/100/1000 BASE-T ports (EH6000/8000 only)
On the EH6000/8000, the 10GbE ports support SFP+ SR-fiber modules. In certain circumstances, you
might want to configure the additional 10/100/1000 BASE-T ports (labeled Gb2, Gb3, and Gb4 on the
Discover appliance) for monitoring instead of the 10G BASE-SR ports.
The Gb1 port is a dedicated management interface and cannot be configured for monitoring.
Depending on your license, the Gb3 and Gb4 ports might be disabled on the ExtraHop system. Contact
1. In your browser, navigate to the Web UI on the ExtraHop appliance at https://<extrahop_ip>/
