z990 Hardware Management Console
A local Hardware Management Console must be connected to its Support Elements using
Local Area Network (LAN) wiring. zSeries 990 provide both token ring and Ethernet options
for the LAN wiring between the Hardware Management Console and the Support Elements.
The necessary LAN adapters for the Support Elements and the Hardware Management
Console may be specified as features on the system order.
Each Support Element has two LAN adapter options. Neither is the default; one of the
following must be selected:
– Dual Ethernet SE
– Token ring/Ethernet SE
The Hardware Management Console has two LAN adapter options. Neither is the default; you
must select one of the following:
– Dual Ethernet HMC
– Token ring/Ethernet HMC (traditional)
Important: Beginning with the next zSeries server, after the IBM eServer zSeries 890 and
990 all new HMCs on all currently marketed zSeries servers are intended to become
closed platforms. They will only support the HMC application and not the installation of
other applications such as the IBM ESCON Director and the IBM Sysplex Timer console
applications.
When available, the next generation HMC is expected to communicate only with G5
Servers, and above (Multiprise 3000, G5/G6, z800, z900, z890, z990).TCP/IP is intended
to be the only communications protocol supported.
