IBM system x3530 m4 (7160k2g, 90y8826 х4, 49y3760, 00d4413) [36/402] Server power features

v Power-supply error LED: Each power supply has an ac power LED and a dc

power LED. When the power-supply error LED is lit, it indicates that the power

supply has failed.

v Video connector: Connect a monitor to this connector. The video connectors on

the front and rear of the server can be used simultaneously.

Note: The maximum video resolution is 1600 x 1200 at 75 Hz.

v Serial connector: Connect a 9-pin serial device to this connector. The serial port

is shared with the integrated management moduleII (IMM2). The IMM2 can take

control of the shared serial port to redirect serial traffic, using Serial over LAN

(SOL).

v USB connectors: Connect a USB device to any of these connectors.

v 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.

v Ethernet link LEDs: When these LEDs are lit, they indicate that there is an

active link connection on the 10BASE-T, 100BASE-TX, or 1000BASE-TX interface

for the Ethernet port.

v Ethernet and system-management connectors:

– IMM2 dedicated mode (default): In this mode, which is the default setting for

the server, the Ethernet 2 connector connects to a network for full

systems-management information control. A dedicated management network

provides additional security by physically separating the management

network traffic from the production network. Meanwhile, the Ethernet 1,

Ethernet 3 and Ethernet 4 connectors are used to connect to the production

network. See “Using the Setup utility” on page 75for more information.

– IMM2 shared mode : In this mode, the Ethernet 1 connector is used to

connect to both the management network and production network.

Meanwhile, the Ethernet 2, Ethernet 3 and Ethernet 4 connectors are used to

connect to the production network. See “Using the Setup utility” on page 75

for more information.

Server power features

When the server is connected to an ac power source but is not turned on, the

operating system does not run, and all core logic except for the service processor

(the Integrated Management Module) is shut down; however, the server can

respond to requests to the service processor, such as a remote request to turn on

the server. The power-on LED flashes to indicate that the server is connected to ac

power but is not turned on.
