2.2.3 Installing the Netra CP3250 Blade Server in anATCA Shelf
If you install the Sun Netra CP3250 blade server with an ARTM, the ARTMmust be
installed first.
Note – Slots 1 through 6 and 9 through14 are available for Sun Netra CP3250 blade
servers. Slots 7 and 8 are reserved for the switch card.

2.2.3.1 Installing an Advanced Rear Transition Module (ARTM)

A compatible ARTM must be used with the Sun Netra CP3250 blade server for rear
I/O access. The ARTM enables access to the network, a boot device, and a console
terminal. Youcan use one of the Netra CP32x0 ARTMs or you can design your own
ARTM-compatible transition module. For more information, see Section1.4.2,
“Advanced Rear Transition Module” on page 1-8.
1. Verify that you have taken the necessary antistatic precautions.
See Section 2.1.1, “Equipment and Operator Safety” onpage 2-2.
2. From the rear of the system, choose the corresponding slot for the ARTM.
The rear transition module must be installed, inline, behind a compatible Netra
blade server.
For example, if the Sun Netra CP3250 blade server will be installed in slot 3, the
corresponding rear transition module must be installed at the back of the system
in slot 3 (FIGURE2-1). If you do not install the rear transition module and the Sun
Netra CP3250 blade server in corresponding slots, the system will recognize the
Sun Netra CP3250 blade server and not the rear transition module.
Note – Slots 1 through 6 and 9 through14 are available for Sun Netra CP3250 blade
servers. Slots 7 and 8 are reserved for the switch card.
