Safety information
To avoid bodily injury or device damage, read the following information carefully before you operate
the network adapter.
General operating safety
To avoid bodily injury or damage to the device, follow these guidelines when you operate the network
adapter:
•
Only H3C authorized or professional engineers are allowed to install or replace the network
adapter.
•
Before installing or replacing the network adapter, stop all services, power off the blade server,
and then remove the blade server.
•
When disassembling, transporting, or placing the blade server, do not use excessive force.
Make sure you use even force and move the device slowly.
•
Place the blade server on a clean, stable workbench or floor for servicing.
•
To avoid being burnt, allow the blade server and its internal modules to cool before touching
them.
Electrical safety
Clear the work area of possible electricity hazards, such as ungrounded chassis, missing safety
grounds, and wet work area.
ESD prevention
Electrostatic charges that build up on people and other conductors might damage or shorten the
lifespan of the network adapter.
Preventing electrostatic discharge
To prevent electrostatic damage, follow these guidelines:
•
Transport or store the network adapter in an antistatic bag.
•
Keep the network adapters in antistatic bags until they arrive at an ESD-protected area.
•
Place the network adapter on an antistatic workbench before removing it from its antistatic bag.
•
Install the network adapter immediately after you remove it from its antistatic bag.
•
Avoid touching pins, leads, or circuitry.
•
Put away the removed network adapter in an antistatic bag immediately and keep it secure for
future use.
Grounding methods to prevent electrostatic discharge
The following are grounding methods that you can use to prevent electrostatic discharge:
•
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
•
Take adequate personal grounding measures, including wearing antistatic clothing and static
dissipative shoes.
•
Use conductive field service tools.
•
Use a portable field service kit with a folding static-dissipating work mat.

Configuring the network adapter
The figures in this section are for illusion only.
Viewing mapping relations between network
adapter ports and ICMs
To view the mapping relations between the network adapter ports and ICM internal ports, log in to
OM and access the Blade Servers > Port Mapping page.
Viewing the identification status of network
adapter ports in the operating system
This section describes how to verify if a network adapter port has been identified in the operating
system. It uses CentOS 7.5 and Windows Server 2016 as examples.
Linux operation systems
1. Execute the lspci | grep QL41000 command to view PCI device information for the
ETH681i network adapter.
The system can identify a minimum of two PCI devices for each network adapter, which
corresponds to two network adapter ports.
Figure 1 Viewing PCI device information
2. Execute the ifconfig -a command to verify that the two network adapter ports are identified.
The port names are determined by the operating system naming rule. If no ports are identified,
install the most recent driver and try again. For more information, see "Installing and
uninstalling a network adapter driver in the operating system."

2
Figure 2 Viewing information about network adapter ports
If NPAR is enabled for the network adapter, you can view 16 PCI devices after executing the
lspci | grep QL41000 command.
Figure 3 Information about a network adapter enabled with NPAR
Windows operating systems
1. Open Network Connections and verify that the Qlogic FastLinQ QL41202H network adapters
can be displayed correctly. This indicates that the ETH681i network adapter has been
identified.

3
Figure 4 Viewing network adapters
2. If the network adapter is not displayed, open Device Manager, and examine if an Ethernet
controller exists in the Network adapters > Other devices window.
If an Ethernet controller exists, an error has occurred on the driver. Install the most recent
driver and try again. For more information, see "Installing and uninstalling a network adapter
driver in the operating system."
If no Ethernet controllers exist, verify that the network adapter is installed securely.
Figure 5 Viewing network adapters
Installing and uninstalling a network adapter driver
in the operating system
The driver used by the network adapter and the installation method for the driver vary by operating
system. This section uses CentOS 7.5 and Windows Server 2016 as examples.
Linux operating systems
Viewing the current driver version
Execute the modinfo qede command to view the current driver version.
