Lenovo 6241, Installation And Service Manual

Page: 46 / 1990

• You can install up to three flash power modules in the standard I/O book.
• You can install only ML2 Ethernet adapters in PCIe slot 10 of the standard I/O book. See “Supported ML2
(Ethernet) adapters” on page 88 for more information about the Ethernet adapters.
• The standard I/O book is connected to microprocessors 1 and 2. The standard I/O book PCIe buses are
also connected to microprocessors 1 and 2.
The following is an illustration of the standard I/O book:

• 3V battery error LED: When this LED is lit, it indicates that a standard I/O book battery error has
occurred.
• Ethernet connectors: Use either of these connectors to connect the server to a network. When you use
the Ethernet 1 connector, the network can be shared with the IMM through a single network cable.
• Ethernet activity LEDs: When these LEDs are lit, they indicate that the server is transmitting to or
receiving signals from the Ethernet LAN that is connected to the Ethernet port.
• Ethernet link LEDs: When these LEDs are lit, they indicate that there is an active link connection on the
100BASE-TX, 1000BASE-TX, or 10GBASE-TX interface for the Ethernet port.
• Ethernet adapter slots: Insert the dual-port or quad-port Ethernet adapters into these slots.
• I/O board error LED: When this LED is lit, it indicates that an error has occurred on the standard I/O book
board.
• Locate LED: Use this LED to visually locate the server among other servers. You can use management
software, such as Lenovo XClarity Administrator software, to light this LED remotely. IMM can also be
used to turn this LED on and off. This LED is functionally equivalent to the locate LED on the front of the
server.
• NMI button: Press this button to force a nonmaskable interrupt to the microprocessor. You might have to
use a pen or the end of a straightened paper clip to press the button. You can also use it to force a blue-
screen memory dump. Use this button only when you are directed to do so by Lenovo Support.
• Serial connector: Connect a 9-pin serial device to this connector. The serial port is shared with the
integrated management module (IMM). The IMM can take control of the shared serial port to redirect serial
traffic, using Serial over LAN (SOL).
• System-error LED: When this LED is lit, it indicates that a system error has occurred. An LED on the front
operator panel is also lit to help isolate the error. This LED is functionally equivalent to the system-error
LED on the front of the server.
