Sun Netra X6270 M2 Server Module Hardware and Software Features

This chapter summarizes the features available on the Sun Netra X6270 M2 server module and contains the following topics:

- Front Panel Indicators, Buttons, and Port

- Attaching Devices to the Server Module

- Replaceable Server Components

##

1.1 Front Panel Indicators, Buttons, and Port

FIGURE 1-1 identifies the front panel buttons, indicators, and ports on the server.

FIGURE 1-1 Front Panel of the Server Module

Figure Legend Front Panel LEDs, Buttons, and Port
1 | Locate LED and button - White
2 | Ready to Remove LED - Blue
3 | Service Action Required LED - Amber
4 | OK/Power LED - Green (blinking or solid state)
5 | Power button/reset
6 | Non-Maskable Interrupt (NMI) button (Service only)
7 | Universal Connector Port (UCP), used for dongle cable
8 | HDD OK/Power LED - Green
9 | HDD Service Action Required LED - Amber
10 | HDD Ready to Remove LED - Blue

| Caution - Do not use the NMI button unless you are instructed to do so by authorized service personnel. The NMI button sends an NMI dump request to the CPUs, which is used by service personnel for debugging activities.

1.2 Attaching Devices to the Server Module

Your system chassis is shipped with a dongle cable that enables you to connect communication devices directly to the front panel of the server module:

- 3-Cable Dongle II (P/N 530-3936 Option #4622A). This cable provides a VGA connector, RJ-45 serial connector, and one dual USB connector. See Appendix C for additional connector pinout information.

Note - The 3-Cable Dongle II is typically provided with each Sun Netra 6000 DC modular system. Additional cables may be ordered.

You can use the VGA or USB connectors on the dongle cable to communicate with the server module BIOS and operating system. Or, you can use the serial connector to communicate with the server module SP.

| Caution - You should use the dongle cable only for configuration and service purposes. Disconnect the dongle cable from the server module after the configuration or service operation is complete to avoid damaging the cable.

FIGURE 1-2 illustrates how to attach the 3-Cable Dongle to the server module universal connector port (UCP).

### 1.2.1 Attaching a USB Drive

You can use a USB drive to communicate with the server module BIOS and operating system. FIGURE 1-3 illustrates how to attach the USB drive on the server module motherboard.

1.3 Replaceable Server Components

FIGURE 1-4 identifies the replaceable component locations with the top cover removed.

FIGURE 1-4 Replaceable Component Locations

Figure Legend Replaceable Server Components
1 | Fabric Expansion Module (FEM) (optional component) Note - Inset (1a and 1b) shows motherboard-facing connections and replaceable components. See Installing or Servicing a Fabric Expansion Module (FEM).
2 | Raid Expansion Module (REM) (optional component) See Replace an Existing REM.
3 | DIMMs (optional components) The DIMMs in FIGURE 1-4 are shown populated with filler panels. See Installing or Replacing Memory Modules (DIMMs). Note - Processor chip contains memory controller. Do not attempt to populate DIMMs sockets next to unpopulated (empty) CPU sockets.
4 | CPUs and heatsinks (up to two CPUs may be installed) See Replace or Upgrade CPU and Heatsink. The minimum CPU configuration shipped includes one CPU with a heatsink. An air baffle is shipped to cover the empty CPU socket (not shown in FIGURE 1-4). Additional CPUs may be ordered. Note - In the example shown in FIGURE 1-4, the CPUs are installed under the two heatsinks.
5 | Storage devices (hard disk drives or solid state drives) Up to four optional storage devices may be installed. See Installing or Servicing a Hard Disk Drive or Solid State Drive.
