3.2 Installing the HMC
In this section we discuss the physical setup of the HMC.
Both the desktop and rack mounted HMC models come with the embedded OS, HMC code,
browse, and eServer Hardware Information Center pre-loaded. Therefore, the HMC can be
unpacked and powered up immediately after the networking components are connected.
With a desktop HMC, the additional ethernet LAN card will need to be installed. There is one
embedded ethernet adapter, so with this additional LAN card, we have the standard two HMC
ports. You cannot use the rear side USB ports. Refer to Figure 3-5.

Figure 3-6 shows part of the rear of the rack mounted HMC system unit. The HMC ports 1
and 2 are located in the center of the image (one ethernet cable is connected). You can also
see the breakout cable, keyboard, display, and mouse.
Attention: When installing a new System i5 system, do not power on the system before
connecting it to an HMC. The Server processor (SP) on a System i5 system is a DHCP
client and will search for a DHCP server to obtain its IP address. If no DHCP server can be
found, then the SP will assign a default IP address. If this occurs, you will have to use ASM
to manually change the IP setting of the SP.
