•At least one Fabric Controller module must be installed in the Core slot for the chassis to boot.

•When a module is installed in a Core slot, it acts as either the master or standby controller for the chassis, with all modules in the system being slaves to the master controller.

•The subnet manager runs on the fabric module installed in the Core slot that has arbitrated to be the master.

•The Core slot module also acts as the switch fabric spine, interconnecting the end-nodes.

Each Core slot is connected to 1 of 2 ports on the Management Interface module. The pairing of core slot to Management I/O module is as follows:

•The Fabric Interface Module in the Core slot #11 is connected to the Management I/O module in slot #15 .

•The Fabric Interface Module in the Core slot #12 is connected to the Management I/O module in slot #16.

Line Interface Modules (LIM)

Refer to “Installing a LIM Module” on page 48 for installation instructions.

The Topspin 270 has hot-swappable Line Interface Modules (LIMs), which are installed in the rear of the chassis; this is opposite of the fabric modules (see Figure 1-2 on page 14). The LIMs provide the physical InfiniBand port interfaces and are 4x over copper. The number of LIMs in your Topspin 270 chassis depends on your particular configuration.

Chassis ID Module

The chassis ID module is hot-swappable, and is located on the rear of the chassis (see Figure 1-2 on page 14).

Figure 1-6:Chassis ID Module

How the Chassis ID is Used

Upon initial boot-up of the Topspin 270, the Chassis ID is read by the system, and the unique information is populated to the rest of the chassis.

The Chassis ID module contains model and serial number information, and logs certain error information. Refer to “Vital Product Data Storage” on page 20.

About Replacing a Chassis ID Module

In the event that a Chassis ID module must be replaced, the replacement module will arrive with your previous serial number and GUID. When a Chassis ID modules is installed, the new Chassis ID is detected. This allows your chassis to maintain the same identification and GUID.

Rack Alarm

The Rack Alarm (also referred to as the Rack Locator) feature is supported with release 2.2.0 and later.
