Rear panel LED state descriptions
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 the super capacitor’s backup power. The way an LED flashes provides further information about what is currently occurring.
NVRAM Status LED (Green/Amber)| State | Meaning |
| Green (solid) | Normal operation |
| Amber (solid) | The NVDIMM or Supercapacitor backup energy source is faulty. |
| Off | Disabled or system powered down. The NVDIMM may contain data in internal flash memory that will be restored on boot. |
| LEDs | Meaning |
| Green | Normal operational mode of an active cluster node. |
| Slow flash (once every three seconds) | The system has been shut down. |
| Medium flash (once every .8 seconds) | The server is available to host file services but is not currently doing so. This also occurs if no EVS is configured, or if all EVSs are running on the other node in a cluster. |
| Fast flash (five flashes per second) | The server is rebooting. |
| Off | The server is not powered up. |
| LEDs | Meaning |
| Amber | Critical failure and the server is not operational. |
| Slow flash (once every three seconds) | System shutdown has failed. Flashes once every three seconds. |
| Medium flash (once every .8 seconds) | The server needs attention, and a non-critical failure has been detected, for example, a fan or power supply has failed. Flashes once every .8 seconds. |
| Off | Normal operation. |
10 gigabit cluster ethernet interconnect ports
The 10 gigabit per second Ethernet (10 GbE) cluster ports allow you to connect cluster nodes together. The cluster ports are used only in a cluster configuration. The 10 GbE ports operate at speeds of ten (10) gigabits per second. The HNAS 5200 and 5300 10 GbE cluster ports use a small form factor pluggable (SFP+) optical connector.
Do not use the 10 GbE cluster interconnect ports to connect to the customer data network (also known as the public data network).
Once connected, each 10 GbE port has two indicator LEDs; one blue and one red. These LEDs provide link status and network activity status information as follows:
| Status/Activity (per port) | Meaning | ||
| Status | Blue on, not flashing | 10 Gbps link present | |
| Blue off | No link | ||
| Red on | Fault with 10GbE cluster port. Check SFP (laser fault, not 10Gb or Copper SFP used) | ||
| Red off | No fault with 10GbE cluster port | ||
| Activity | Blue flashing | 10GbE cluster port activity | |
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.
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.
Fibre channel storage ports
The four FC ports operate at speeds of 4/8/16 Gbps. FC ports use an enhanced small form factor pluggable (SFP+) optical connector.
The SFP+ ports can be removed from the chassis.
| Status/Activity (per port) | Meaning | ||
| Status | Green (solid on) | Server booting | |
| Green off | Link down | ||
| Activity | Top Green LED(flashes for activity, other speed LEDs off) | 16G FC link | |
| Middle Green LED (flashes for activity, other speed LEDs off) | 8G FC link | ||
| Bottom Green LED (flashes for activity, other speed LEDs off) | 4G FC link | ||
| HBA fault(LEDs flash in sequence) | Host Bus Adapter faulted | ||

There are six 10 GbE ports that use enhanced
small form factor pluggable (SFP+) optical connectors, shown as follows:
Once connected, each 10 GbE port has two indicator LEDs; one blue and one red. These LEDs provide link and network activity status information as follows:
| Status/Activity (per port) | Meaning | |
| Status | Blue on, not flashing | 10 Gbps link present |
| Blue off | No link | |
| Red on | Fault with 10GbE port. Check SFP (laser fault, not 10 Gb or Copper SFP >5m used) | |
| Red off | No fault with 10GbE port | |
| Activity | Blue flashing | 10 Gbps link 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 retention latch |
| 2 | Power cord connector |
| 3 | PSU status LED |
| 4 | PSU fan exhaust |
| 5 | PSU handle |
| Status | Meaning |
| Green | DC output operating normally |
| Flashing Green | No AC power or DC output fault |
| Off | Standby power fault or neither PSU is powered from AC mains |
| Flashing Amber | Internal PSU fault (over voltage, over-current, over temperature or fan failure) |
If the Power status LED is off, unplug the power cable, wait 10 seconds, then reconnect the cable. If the Power Status LED remains off, the PSU has failed and must be replaced.
If the amber status LED is flashing, 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.
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.
| LED Color | Status | Definition |
| Green | Flashing | Active |
| LED Color | Definition |
| Off | No connection/10 Mbps |
| Amber | 1 Gbps |
| Green | 100 Mbps |
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.

10/100/1000 Ethernet management ports
The 10/100/1000 Ethernet management ports are used to connect the server or node to the customer facing management network and the private management network, or to connect directly to another device for management purposes.
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.
