C.4 Installing the Bypass Card
WARNING: If you have any onboard NICs in your server, you must disable them so that the bypass
card appears as eth0 and eth1. To disable the onboard NICS, reboot to enter the BIOS settings area
and disable them. The exact procedure varies depending on the specific BIOS.
The bypass card is a NIC card installed in the Novell ZENworks Network Access Control
Enforcement server.
To install the bypass NIC card:
1 Power down the Novell ZENworks Network Access Control Enforcement server.
2 Open the Novell ZENworks Network Access Control Enforcement server case.
3 Install the card in an empty slot.
