Hardware Management Console and Support Element wiring options
A local Hardware Management Console must be connected to its Support Elements using Local Area
Network (LAN) wiring. The Hardware Management Console and the Support Elements both come with
Dual Ethernet LAN adapters.
The communication protocol (TCP/IP) used in Support Element to Hardware Management Console
communication is defined for both adapters in the Support Elements.
Notes on wiring with multiple adapters:
1. The Hardware Management Console supports dual Ethernet paths to Support Elements. This allows
automatic redundant network paths so that the failure of a single network has no affect on Hardware
Management Console to Support Element communication.
2. When configuring multiple adapters the address must be defined in different subnets.

Because HMCs FC 0091 and FC 0092 only come with dual Ethernet features, no additional explanation of
wiring scenarios is offered here.
Trusted Key Entry (TKE)
zEC12 may have a Crypto Express3 or Crypto Express4S feature for applications where extensive data
security is required. For these systems, there is a separate console available for authorized access to the
Crypto Express3 or Crypto Express4S feature. This console is named the Trusted Key Entry (TKE)
workstation.
