ID/CSS/Global error indicator

Figure 41: ID/CSS/Global error indicator (HNC M1)

Figure 42: ID/CSS/Global error indicator (HNC M2)

No.	Meaning
1	ID/CSS/Global error indicator

Element	Meaning
ID	ID indicator (blue) Lights up blue when the HNC has been selected by pressing the ID button. To deactivate, press the button again.
CSS	CSS and Global error indicator (yellow/orange)
	Generally, the states of these indicators have the following meanings: Do not light up when the HNC is OK. If the event is still acute after a power failure, the indicator is activated after the restart. Light up when a prefailure event was detected. The indicator also lights up in standby mode. Flash when an error was detected. The indicator also flashes in standby mode. Irrespective of the color, when an indicator lights up or flashes this indicates an error event. Please notify customer support.

LAN indicators

Figure 43: LAN indicators (HNC M1)

Figure 44: LAN indicators (HNC M2)

No.	Meaning
1	LAN activity indicator Lights up green if a LAN connection exists. Does not light up if no LAN connection exists. Flashes green when a LAN transfer is in progress.
2	LAN speed indicator Lights up yellow for a LAN transfer rate of 1 Gbps. Lights up green for a LAN transfer rate of 100 Mbps. Does not light up for a LAN transfer rate of 10 Mbps.

Indicator on hot-plug power supply unit

Figure 45: Indicator on hot-plug power supply unit

No.

Meaning

1

Indicator on hot-plug power supply unit (two colors) Flashes green when the HNC is switched off, but line voltage is present (standby mode). Lights up green when the HNC is switched on and functioning properly. Flashes orange when a predictable error has been detected, but the power supply unit is still running.1) Lights up orange when no line voltage is present or the power supply unit has failed.

1)	The following events are detected as predictable errors: The temperature is very high. The power consumption is very high. The current strength is very high. The fan speed is very low In each of these cases please notify Customer Support.

Assignment of the PCIe slots

The assignment of the PCIe slots differs from HNC M1 to HNC M2.

PCIe slot assignment on an HNC M1

Figure 46: Principle of PCIe slot assignment at the rear of the device (HNC M1)

The figure shows the PCIe slots of the HNC M1:

PCIe slot	Assignment
S1	Not assigned; an optical LAN card is optionally possible
S2	4-port LAN card
S3	FibreChannel card

PCIe slot assignment on the HNC M2

Figure 47: Principle of PCIe slot assignment at the rear of the device (HNC M2)

The figure shows the PCIe slots of the HNC M2:

PCIe slot	Assignment
S2	4-port LAN card
S3	FibreChannel card
S4	not assigned; an additional 4-port LAN card or a 10 GbE LAN card with 2 optical or RJ45 interfaces are optional
