• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible
straps with a minimum of 1 megohm ±10 percent resistance in the ground cords. To provide proper ground, wear the strap
snug against the skin.
• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on
conductive floors or dissipating floor mats.
• Use conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.
For more information on static electricity or assistance with product installation, contact an authorized reseller.

Collecting symptom information

Before troubleshooting a system issue, collect the symptom information. Download the Active Health System Log using the
Active Health System Viewer, if possible.
For more information, see the Active Health System Viewer user guide on the Hewlett Packard Enterprise website (http://
www.hpe.com/support/ahsv-docs).

Preparing the EL8000 system for diagnosis

Procedure
1. Verify that the system is in the proper operating environment with adequate power, air conditioning, and humidity control.
2. Record any error messages displayed by the system.
3. Collect all tools and utilities necessary to troubleshoot the issue, such as a Torx screwdriver, loopback adapters, an ESD
wrist strap, and software utilities.
For product-specific information, Hewlett Packard Enterprise recommends that you have access to the product
information.
4. Review the iLO Integrated Management Log (IML).
5. Record the data displayed in the iLO logs.

The CM configured with static IP address reverts to DHCP when moved to a new chassis

Symptom
The CM configured with static IP address reverts to DHCP when moved to a new chassis.
Cause
The network stack compares the MAC address which is used when the configuration was saved against the current MAC
address. If the current MAC address does not match, the configuration reverts to default. The MAC address of the CM is saved
in the chassis midplane. Moving the CM between chassis results in a mismatch between the address saved in the configuration
and the current address. Hence, the CM reverts to DHCP.
