Firmware

The Administration settings provide an interface to upload and delete the firmware on ExtraHop appliances.

The firmware file must be accessible from the computer where you will perform the upgrade.

Before you begin

Be sure to read the

release notes

for the firmware version that you want to install. Release notes contain

upgrade guidance as well as known issues that might affect critical workflows in your organization.

Upgrade the firmware on your ExtraHop system

The following procedure shows you how to upgrade your ExtraHop system to the latest firmware

release. While the firmware upgrade process is similar across all ExtraHop appliances, some appliances

have additional considerations or steps that you must address before you install the firmware in your

environment. If you need assistance with your upgrade, contact ExtraHop Support.

Pre-upgrade checklist

Here are some important considerations and requirements about upgrading ExtraHop appliances.
•

A system notice appears on Command and Discover appliances connected to ExtraHop Cloud Services

when a new firmware version is available.

•

Verify that your Reveal(x) 360 system has been upgraded to version 8.7 before upgrading your self-

managed sensors.

•

If you have multiple types of ExtraHop appliances, you must upgrade them in the following order:
1. Command appliance
2. Discover appliances
3. Explore appliances
4. Trace appliances

•

If you have a Command appliance, apply the following guidance:
•

For large Command appliance deployments (managing 50,000 devices or more), reserve a

minimum of one hour to perform the upgrade.

•

The Command appliance firmware version must be greater than or equal to the firmware version

of all connected appliances.

•

If you have Explore appliances, apply the following guidance:
•

Do not upgrade Explore appliances to a firmware version that is newer than the version installed

on connected Command and Discover appliances.

•

After upgrading the Command and Discover appliances, halt the ingest of records from the

Command and Discover appliances before upgrading the Explore appliance. If you are upgrading

from a firmware version prior to 7.4, temporarily

remove any connected Explore appliances

or alternatively,

disable triggers

that commit records and disable the

automatic flow records

setting. If you are upgrading from firmware version 7.4 or later, after upgrading the Command

Discover appliances

disable record ingest on the Explore cluster

before upgrading the Explore

appliance.
You must re-enable these settings after all nodes in the Explore cluster are upgraded.
