Server rear panel

The rear panel of the server contains three (3) status LEDs that indicate server status and two (buttons) that are used to power up and reset the server.

The NVRAM, power, and server status LEDs indicate whether the server is powered, its operational state, and whether the NVRAM is currently being protected by battery backup power. The way an LED flashes provides further information about what is currently occurring.

When power cables are connected to the PSUs, the server normally powers up immediately. If, after 10 seconds, the LEDs on the power supplies are lit, but the Power Status LED is not lit, press the PWR button to restore power to the system. Open a case with Hitachi Vantara Support Connect to get the problem resolved.

Pressing the reset button when the server is powered on causes a hard reset of the server.

This reset occurs after a 30-second delay, during which the server status LED flashes rapidly and the server attempts to shut down properly. Even with the delay, pressing the reset button does not guarantee a complete shutdown before rebooting. Only press the reset button when the server is powered on to recover a server which has become unresponsive. Pressing the reset button at this time may produce a dump automatically.

The GE Ethernet Network ports are used to connect the server or cluster node to the customer's data network (also called the public network), and these ports may be aggregated into a single logical port (refer to the Network Administration Guide for more information on creating aggregations). GE ports operate at speeds of up to one (1) gigabit per second, and require the use of a standard RJ45 cable connector.

The GE Customer Ethernet Network ports are labeled as shown next:

Once connected, each GE port has two indicator LEDs; one green and one amber. These LEDs provide link status and network activity status information as follows:

The 10/100 Private Ethernet Network ports function as an unmanaged switch for the private management network (refer to the Network Administration Guide for more information on the private management network). These ports are used by the server and other devices (such as an external SMU and other cluster nodes) to form the private management network. There are no internal connections to the server from these ports; instead, when joining a server to the private management network, you must connect from one of these ports to the management interface port on the server.

The 10/100 ports operate at speeds of up to 100 megabits per second, and require the use of a standard RJ45 cable connector.

The 10/100 Private Management Ethernet Network ports are labeled as shown next:

Once connected, each 10/100 port has two indicator LEDs; one green and one amber. These LEDs provide link status and network activity status information as follows:

FC ports operate at speeds of two to eight (8) gigabits per second. FC ports use an enhanced small form factor pluggable (SFP+) optical connector.

The SFP+ ports can be removed from the chassis.

A standard serial (RS-232) port, used to connect to the server for management purposes. See RS-232 serial management port for more information.

The server monitors the operational status of the power supply modules so that the management interfaces can indicate the physical location of the failed PSU. LED indicators provide PSU status information for the state of the PSU.

If the DC Power status LED is off, unplug the power cable, wait 10 seconds, then reconnect the cable. If the DC Power Status LED remains off, the PSU has failed and must be replaced.

If the PSU status LED is on, unplug the power cable, wait 10 minutes, then reconnect the cable. If the PSU Status LED remains off, the PSU has failed and must be replaced. See Replacing a power supply unit for more information on replacing a PSU.

Mains power connections are an IEC inlet in each power supply. Each PSU is only powered from its mains inlet. Two power feeds are required for the system. PSU units do not have an on/off switch. To turn on power, simply connect the power cable. To turn off the unit, remove the power cable.

When both PSUs are installed, if only one PSU is connected and receiving adequate power, the fans on both PSUs will operate, but only the PSU receiving power will provide power to the server.

Each power supply auto-ranges over an input range of 100V to 240V AC, 50 Hz to 60 Hz.

The 10/100/1000 Ethernet ports operate at speeds of up to one (1) gigabit per second, and require the use of a standard RJ45 cable connector. Once connected, each GE port has two indicator LEDs; one on the top left and the second on the top right of the port.

In addition to eth0 and eth1, an IPMI LAN is also located on the I/O back panel. The amber LED on the right indicates activity, while the green LED on the left indicates the speed of the connection. Refer to the following table for more information.

Any VT100 terminal emulation interface can be used to access to the CLI so that you can perform management or configuration functions. Connect the terminal to the serial port on the rear panel of the server, then set the host settings to the values shown in the following table to ensure proper communication between the terminal and the server.
