Server rear panel - all models

The rear panel of all server models features numerous ports, connectors, switches, and LEDs. The rear panel also offers access to the server's power supply units (PSUs).

Power button (PWR)

Under normal circumstances, the power button is rarely used. However, the power button can be used to restore power to the system when the server is in a standby power state.

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.

NoteDo not use the power button during normal operation of the server. Pressing the power button immediately causes an improper shutdown of the system. The PSUs will continue to run.

Reset button (RST)

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.

CautionIf the server is non-responsive, see Restarting an unresponsive server. Do not pull the power cord. Pulling the power cord does not produce a dump.

Fibre channel storage ports

The Fibre Channel (FC) storage ports allow you to connect the server with other FC devices, such as storage subsystems.

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.

NoteWhen removed, the 10 GbE and 8 GB Fibre Channel (FC) SFP+ storage ports are indistinguishable from one another except for their part numbers. The part number is located on the side of the port housing and is only visible when the port is removed. Part number prefixes are different as follows:
  • 10 GbE: FTLX<number>
  • FC: FTLF<number>

10 Gigabit Ethernet customer data network ports

The 10 Gigabit Ethernet (GbE) customer data network ports are used to connect the server or cluster node to the customer's data network (also called the public data network). These ports may be aggregated into a 1, 2, 3, or 4 aggregated port.

See the Network Administration Guide for more information on creating aggregations.

The 10 GbE ports operate at speeds of ten (10) gigabits per second. The 10 GbE ports use enhanced small form factor pluggable (SFP+) optical connectors.

NoteThe 10 GbE customer data network ports cannot be used to interconnect cluster nodes.

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

Activity Amber flashing Network activity
Amber off No network activity

Power supply units

The server has dual, hot-swappable, load sharing, AC power supply units (PSUs). The PSUs are accessible from the rear of the server.

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.

Item Description
1 PSU fan exhaust
2 Power cord connector
3 PSU retention latch
4 PSU handle
5 DC power status LED
6 PSU status LED
7 AC power status LED
NoteThere are no field-serviceable parts in the PSU. If a PSU unit fails for any reason, replace it. See Replacing a power supply unit for information about replacing a power supply.
DC power status LED (green)
Status Meaning
Green DC output operating normally
Off DC output not operating

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.

PSU status LED (amber)
Status Meaning
Off PSU operating normally
Amber PSU internal failure (over temperature, fan, or internal component)

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.

AC power status LED (green/amber)
Status Meaning
Green Receiving AC power and operating normally
Off Not receiving AC power (check mains and power cable connections)

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.

CautionIf the server is non-responsive, see Restarting an unresponsive server. Do not pull the power cord.

Ethernet management ports 0 and 1

Ethernet management ports 0 and 1 are standard 10/100/1000 Ethernet ports that are used to connect to the server for management purposes. Two LAN ports (eth0 and eth1) are located on the I/O back panel of the motherboard. Each Ethernet LAN port has two LEDs.

The green LED indicates activity, while the other link LED may be green, amber, or off to indicate the speed of the connection.

Refer to the following tables for more information.

Serial port

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

USB ports

Standard USB connectors. These ports are used to connect USB devices to the server during some operations.

Valid USB devices include:

  • Flash drives
  • External hard drives
  • USB keyboards

Valid operations include:

  • Management
  • Install
  • Upgrade
  • Update
  • Repair
NoteThe USB ports should not be used without guidance from customer support.

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.
