Introduction to Hapi
Modular by Design
Hapi, the son of Horus. Born from the most flexible and sonically transparent audio interface and
providing the same RAVENNA / AES67 connectivity as its father, Hapi is both the perfect primary
interface for smaller systems as well as the ultimate accessory for a system using Horus where control
room I/O is required. Hapi was designed to give its users an Audio I/O channels flexibility while offering
an unprecedented level of quality in such a small form factor.
Providing as standard; 8 channels of AES- EBU I/O plus 8 ADAT or 2 SPDIF I/O (on TOSLINK) and 2
slots for AD8D/AD8P, DA8/DA8P and MADI option cards. Once the Hapi is fully loaded with option
cards, it is capable of achieving 88 inputs and 90 outputs @ 1FS There are indeed 2 more output
channels than input channels, including the Stereo Headphone Monitoring.
Route Signal Anywhere
Hapi has been designed so that any input can be routed to any number of outputs as required
simultaneously. With comprehensive routing pages accessible both locally on the touchscreen and by
remote access using a standard web browser, Hapi is the answer to signal flow management in your
studio.
Green Built
For environmentally-conscious users, Hapi has been designed meticulously in order to keep power
consumption at an incredible minimum. A fully loaded Hapi running all channels of phantom power will
only draw about 30W, making it more affordable to run than your kitchen lights.
Hapi Key Features
• Up to 88 inputs and 90 outputs @1FS
• 8x AES/EBU + 8x ADAT or 2x SPDIF (Optical)
• Works from 44.1kHz to 192kHz (Premium up to DXD/DSD256)
• Signal routing from any input to any combination of outputs
• RAVENNA / AES67 Compatible
• Browser-based remote access using any web enabled device
• AC or DC power supply options
• Modular design for additional analog and Digital I/O
• Near-zero latency from in to out (<1ms)
• Main rotary control button
RAVENNA
The Hapi has been designed so that the MADI, AES, SPDIF/ADAT and Analog modules can all feed
into or take their sources from the network over RAVENNA streams, providing up to 88 channels of I/O
@ 1FS over a single CAT5e or CAT6 cable to any other RAVENNA devices on the network.
The RAVENNA connection on the Hapi allows for not only audio, but also control and sync information
to flow through as well. Send Timecodes and Wordclock directly to the Hapi unit over the same network
as your audio. The RAVENNA port even provides for remote control access to the configuration and
entire routing of the unit itself! Support for: LTC/Video Ref/WCK
RAVENNA is a layer 3 IP based protocol. In environments where existing networks are already in
place, RAVENNA subnets can slip right into place with no additional outlay. In laymen’s terms, this
means that you can connect your Hapi to a properly configured network exactly as you would your PC
or Mac, with no additional technology required.
RAVENNA is a “mission critical” protocol, meaning that is has been designed to ensure immensely low
jitter rates and latencies (sub-millisecond) and ensures that every single sample gets to where it needs
to go without fail. Hapi also provides a secondary, redundant RAVENNA connection allowing for
uninterrupted use, even when a network connection fails.
Refer to the RAVENNA User Guide and the MassCore-RAVENNA Configuration Guide for more details

Line Output Level calibration
The DA8 and DA8P modules feature both hardware level settings and a software fine adjustment to
align the Analog Output levels to whatever local/organization operational levels are mandated.
On DA8/DA8P cards from run 7 upwards, the hardware level setting is done via software through the
option “max output level” in each DA’s setting page.
On DA8/DA8P cards prior to run 7 the hardware level setting is in the form of 4 DIP switches per output
channel
The Hardware settings will usually be set only once, at product installation, and only if the desired
Operating Line Level differs from the default ex-factory settings of +18 dBu for 0 dBFS.
Procedure for Hardware alignment (for DA8 prior to run 7):
1. Shut down your Hapi.
2. Unscrew all DA8 modules that need adjustment.
3. Pull gently out (5-7 cm is enough) to access the DIP Switches. There is one block of 4 dip switches
per channel. Channel 1 is labeled S1, channel 8 is labeled S8.
4. Set the DIP Switches as per the table legend printed on the DA8 module card

Output Level calibration Example:
Assuming your operating Level is 21 dBu for 0 dBFS (typical of French Radio Broadcasters), you
should set the DIP Switches all OFF (DIP Switch positioned to the left, with respect to the picture
below) to set maximum Output Level to +24 dBu (since there is no 21 dBu hardware setting)
Page 19

Hapi User Manual
Once this is set and the DA modules are screwed back in place. Power up the Hapi and go to the Hapi
Setup Page>Module, select each D/A module for software calibration.
In this example case set the software attenuation to - 3 dB (see image below), so the overall result ends
up at 21 dBu for a Full Scale signal
The Hapi software Output Attenuation range is from -60dB to 0dB
How to connect the symmetrical line out to an unbalanced input
Never attempt to short pin 3 (or pin 2) to Ground on Hapi DA's output, since the Hapi Line Out driving
circuitry is symmetrical but not floating.
Furthermore, as Unbalanced Inputs are traditionally more sensitive than Balanced Inputs, the - 6dB
Analog level achieved by using only one of the Hapi symmetrical outputs, will offer better signal level
adaptation with less risks of overdriving the Unbalanced Inputs connected to the Hapi.

IOM-HAPI-MADM/MADS
The MADI optional Module card (
MADM
- Multimode /
MADS
– Single mode) provides a channel count
of 64 inputs and 64 outputs @1FS
IOM-HAPI-MADM/MADS Features
• MADI Optical and Coaxial inputs and outputs
• 64 discrete channels of digital input and output (extended mode) at 1FS
• Up to 384 kHz sampling rate
• 24-bit resolution
• Fully compliant MADI (AES 10-1991)
• 2 BNC and 1 SC connectors (Multimode or single mode)
Single mode fibers have a lower power loss characteristic than multimode which means that it supports
longer runs but single mode fibers are more expensive. The multimode version (IOM-HAPI-MADM) is
the most widely used optical MADI connection, but for fiber lengths of more than 600m Merging
Technologies recommends to use the single mode version (IOM-HAPI-MADS).

Hapi key features
Modular analog interfacing
Hapi allows the user to choose between Analog inputs and Analog outputs and MADI I/O required for
each unit. Hapi provides a total of two universal I/O slots which can accept a combination of Mic/Line
modules and or Line output cards and or a MADI module. Users can configure their Hapi with any
combination.
For instance, in a studio environment, 8 A/D (1X IOC-AD8/P) and 8 D/A (IOC-AD8/P) will allow for 8
inputs from the live room and 8 outputs to feed studio monitoring and foldback to the artist.
Modular Device connectivity
Any of the modules listed below (A/D, D/A, MADI, AES, ADAT/SPDIF, RAVENNA) can be
interconnected in any way the user chooses. Simple and easy routing pages enable the user to source
signal from any module, and send it to any other combination of modules. An A/D Module could feed 8
Channels of AES Outputs. At the same time, it could feed to 8 MADI channels, or even the RAVENNA
stream as well. This is the function that allows the user operate with the Hapi in either a standalone
(Analog to MADI/AES AD/DA) or in RAVENNA Mode, which connects the audio to a RAVENNA
network (described below).
With such a wealth of different outputs, it made sense to apply a “route to” instead of a “route from”
philosophy in the way Hapi presents its routing pages. After an initial learning period, you will
understand that this is a much more efficient way to present so many routing options in an easy to
unfold process. So always ask yourself first which output is being considered and then decide what
input signal will feed that output and you will be offered all logical and valid choices at every step. It also
made sense to limit the granularity of routing options to blocks of 8 channels, as a good compromise
between flexibility and complexity.
AD8 / AD8P Remote controlled Mic/Line A/D module
The AD8 (works up to 192 kHz) and the AD8P (works up to DXD/DSD256) are remote controllable,
extremely high-quality Microphone pre-amplifiers with a switch on each channel to route the signal
through dedicated line level circuitry instead. The remote control is achieved over Ethernet, via the
RAVENNA Port at the back of the chassis. With all standard analogue controls also available via
remote (Phantom power on a “per channel” basis, phase invert, HPF) and a Gain stage reaching from 10dB all the way up to +60dB, these modules are not only easy to use, but completely transparent to
listen to as well.
DA8 / DA8P Safety Conscious Analogue Line output Modules
The DA8 (works at sample rates up to 192 kHz) and DA8P (works at sample rates up to DSD) are
specifically designed with the user’s speakers in mind. Incorporating analogue mute circuitry, the DA8/P
modules provide protection against spurious transients that may occur during Sample rate changes and
power cycling “clicks” and “pops” which can damage not only speakers, but also the listener’s ears.
When you add to that a noise floor of less than -125dB, these are the ultimate analog outputs for any
monitoring system.
ADA8 Remote controlled Mic/Line A/D module with transparent Analog output
The ADA8 work at sample rates up to 192 kHz.
DC power supply options
Your Hapi interface can be fitted with a DC power supply input, this can be used to battery power the
device or as a secondary power input.
The DC power supply option can be used in two way
1- Battery power: The Hapi can be operated from battery, or any external DC adapter provided the
voltage is between 10V and 14V
2- Redundant power supply: The Hapi can be operated in a redundant way when using the
standard AC power inlet and an external 12V DC adapter connected to the DC input of Hapi, in
this configuration either power input can fail or be removed without creating any disruption in
the device’s operation.

Hapi User Manual
MADI (Module)
A MADI module is available and can be fitted in one of the Hapi slots. It provides users with up to 64
channels of MADI I/O for use with the system. The signal sent to the MADI Outputs (both Coaxial and
Optical are available simultaneously) are configurable in blocks of 8 channels and can be sourced from
any other module in the Hapi.
Note: Only one MADI module can be fitted per Hapi, please refer to the MADI module section above.
AES-EBU
1 x D-SUB25 connectors providing 8 channels (4 AES pairs) of AES-EBU I/O are Included as standard
(as is the MADI module).
ADAT/SPDIF
8 ADAT I/O or 2 SPDIF I/O (on TOSLINK) are Included as standard. This module is supported up to
2FS (96 kHz)
Signal routing paradigm
Hapi is quite possibly the most flexible audio interface ever designed. Users can literally route any input
signal to any output module. Better yet, it can route any input signal to any combination of output
modules. Routable in blocks of 8 channels, a user can send 8 Mic Inputs to 8 AES outputs. At the same
time these 8 mic inputs can also be sent via the MADI outputs and included in the RAVENNA stream.
RAVENNA IP Audio
Using RAVENNA IP audio, Hapi can connect to a standard network, using off the shelf switches and
other IT technology to become a node on a LAN. From that point, any other RAVENNA node can
receive information from and deliver information to, any combination of RAVENNA devices on the
network. It is a revolution in Audio technology and will soon mean the end to costly audio routers and
matrices and allow any facility an immense amount of flexibility. From Broadcast and TV/Film postproduction, to music, live events, theatres, cruise ships and many more applications, the RAVENNA
Enabled Hapi interface will reinvent how systems come together.
Synchronization
Audio is not the only information that can pass down the RAVENNA connection. Hapi is also able to
send sync (LTC) down the same wire to and from the Hapi unit. For more details refer to the RAVENNA
network guide available on www.merging.com

Installing an additional Hapi I/O Module
Installing additional Hapi I/O Cards ( or DA8/DA8P)
Before you start
- Place the Hapi unit on a hard, dry surface or mount it onto a 19” rack and leave plenty of room
for air convection.
- In order to meet the EMC requirements of directives 89/336/EEC and 93/68/EEC, and in order
to obtain the high performance possible for the Hapi unit, you must use correctly shielded
cables of good quality for all external connections when installing the Hapi unit. For the power
connection, a normal unshielded power cable with a proper ground can be used.
- Make sure that your sound system is at a safe volume level.
Hardware Installation
This section will take you through installation of your Hapi unit. We will describe how to mount the I/O
modules and the power, audio and digital cable connections that can be accessed on the rear panel.
*PLEASE ENSURE THAT YOUR HAPI UNIT IS SWITCHED OFF BEFORE ATTEMPTING TO
CONNECT ANY CABLES TO THE UNIT.*
If you need to mount an I/O module at a later stage, the following procedure is used.
1. Place the shutdown Hapi unit on a dry steady horizontal surface. Remove all cables (including
the power cable).
2. On the back of the Hapi unit there are 2 slots for mounting the Analog I/O cards or a MADI
card.
3. To remove blind plates from I/O module slots, remove the 2 screws on either side of the plate.
Use a Phillips (cruciform) screwdriver tool size 2
4. Only remove the number of blind plates necessary to fit the I/O module(s). If only one I/O slot is
installed, remove only 1 blind plate. If 2 I/O slots are installed, remove 2 blind plates.
5. It is very important to insert the I/O card horizontally and carefully into the Hapi unit. There are 6
set of guides inside the Hapi unit to guide the I/O cards correctly into place. Do not use force in
any way to insert the I/O card. This may damage the card. Slide card slowly as picture below
shows.
6. When the cover plate of the I/O card covers the hole created by removing the blind plate, the 2
screws from the blind plate are mounted in the sides of the I/O card. Tighten the screws
carefully and be careful not to damage the threads.
7. After inserting the I/O module, the Hapi unit might need to be initialized. If this is the case,
please follow the instructions received with the I/O module.

Assembling the rack mount ears
Hapi is delivered with two rack mount ears for easy installation into a 19” rack.
The ears can be mounted either on the front or the rear of the device.
Installing the rack mount ears on the front panel
1. Turn off and unplug your Hapi
2. Unscrew the eight (8) M3x5 screws located on the side of the device (4 screws per side)
3. Place the rack mount ears on the side of Hapi, as shown in the pictures below
4. Fix the ears with the four (4) M3x8 screws delivered with the ears
Installing the rack mount ears on the rear panel
1. Turn off and unplug your Hapi
2. Place the rack mount ears on the side of Hapi, as shown in the pictures below
3. Fix the ears with the four (4) M3x8 screws delivered with the ears
Hapi recommended placement in Rack
Due to confined space in a Rack furniture, adequate spacing (and ordering) between multiple Hapi or
Horus units will play a significant role on the units temperature. Although Merging has spent
considerable time in optimizing the Hapi power consumption in every aspect possible, the units are still
drawing an average of 30W. The dissipation of the related heat produced by this consumption is
therefore highly dependent on the airflow and natural air convection around those units.
With highly loaded Horus units (more than 3 I/O Analog modules per unit) or Hapi units (2 I/O Analog
modules per unit), Merging recommends a free space of 1U above each unit to ensure adequate
cooling of the devices

Installing the Merging PCIe Ethernet Controller Card
NET-MSC-GBEX1
Detailed steps on how to install the NET-MSC-GBEX1 PCIe card in your PC.
1. Power down your PC and switch it off at the wall. Remove the screws holding the top or side of the
case on and carefully slide off the panel.
2. Wearing an anti-static wristband is desirable whenever working with sensitive electrical equipment.
Keeping one hand on a metal part of the case will have the same effect, though you may need both
hands when installing certain items of hardware.
3. Locate an empty PCIe slot and remove the metal backing plate by removing the screw holding it in
place and carefully sliding it up and out. In some cases, there are no backing plates and you will need
to remove a length of metal instead. Do this using a flat-blade screwdriver and/or pliers, taking care to
avoid any sharp edges left behind.
4. Next, remove the NET-MSC-GBEX1 card from its envelope bag and line it up with the vacant PCIe
slot as shown below.
Page 36

5. Push down gently at first, ensuring you have the pins lined up correctly with the slot, and then apply
more force to slot the card home fully.
6. Use the screw which held the backing plate in place to secure the card and check that the card sits
properly.
Finally, replace the case cover(s) and plug your machine back in.
6. At “First Power Up” Windows will discover the Merging Ethernet PCIe card

Hapi power ON
Connecting the Power Cable
The Hapi unit runs on 85-240V, 50-60 Hz AC voltage. Excessive voltages can seriously damage the
Hapi unit, so make sure that your AC power matches the voltage of your Hapi unit. When you connect
the power, use the cable you received with your Hapi unit and plug it into a grounded outlet.
For safety and EMC reasons, and to prevent audio hum, the system must be properly grounded. If your
power source does not have a standard three-prong socket, the system must be grounded in another
appropriate manner.
As an option Hapi can also be powered from a DC power source (10-14V), contact your local reseller
about this option.
Hapi DC power input
Hapi can be delivered with a DC input capability, when this option is ordered a 4 pins connector
(HR10A-7R-4S) is installed left to the AC power connector. The mating part which is also delivered is a
Hirose HR10-7P-4P.
The pinout of this connector is:
- Pin 1: GND
- Pin 4: 12V
- Pins 2 and 3: not connected
The DC power input accepts voltages from 10V to 14V for a maximum power consumption of 30W.
As an option, Merging does also provide an external AC/DC 30W converter with the appropriate
counter-part connector already mounted. Its product code is PSU-AC/DC-30W.

PTP Clock The Precision Time Protocol (PTP) is a protocol used to synchronize
clocks throughout a computer network. Also known as IEEE 1588, it is a
protocol designed to synchronize real-time clocks in the nodes of a distributed
system that communicates using a network. RAVENNA is based on and uses
V2 of this IEEE standardized protocol. PTP Clocks allow for time resolution to
the Nanosecond.
Master: indicates that the current Hapi is the PTP Master
Slave: The Hapi is slave to another PTP Master
The Hapi will always try to be the PTP Master. If multiple Hapi’ or Horus’ are
used in a network environment, the Hapi set in this order will have the PTP
Master priority, using the Best Master Clock Algorithm (BMCA):
1. Video sync
2. Word Clock
3. AES
4. ADAT/SPDIF
5. MADI
6. Internal
7. RAVENNA (always slave unless there is no PTP master available)
Sync Color table: Dark Blue: Signal present Red: Unlocked
Light Blue: Signal valid Yellow: Locking
Black: No Signal Green: Locked
Note: When two or more Hapi are connected together through an Ethernet network, one of them will always be
automatically selected as master, the other Hapi' will be forced into slave state and therefore will not be
synchronized to wordclock or audio input. However, this is not a problem since all Hapi' will be synchronized.
Status: LTC IN: Corresponds to the incoming LTC frame rate
Hapi PTP status: MASTER or SLAVE
Video Format Detected:

Frequency: The long-term measured Frequency (in Hz) and deviation in ppm (parts per
million) between the signal the unit is locked on to and the internal reference.
Delta: The short-term (instantaneous) time offset between the reference signal and
the internal (considered as ideal) reference, measured in nanoseconds (ns).
In other words, the delta indicator over a RAVENNA network will report the
delta in ns between the master and the slave.

PreAmp Menu
The PREAMP (A/D) menu becomes active if you have 1 or more AD8(P) modules installed in the Hapi
unit, giving full access to the Input controls. Please see below for a description of the buttons available.
All Active: Will select all 8 input channels for function and level grouping
Inactive: Adjustments to the input settings and level affect only the selected
channel only
Note the All button will group all inputs of the same type (Mic or Line)
Gain The Rotary Control will give the user control over the Gain level with
increments/decrements in 0.5 dB steps
The Gain range goes from 0 dB to +66.0 dB from left to right
In Mic mode (M): Sets the Mic Preamplifier’s Gain
In Line mode (L): Sets the Line Input Sensitivity
A value of 0dB corresponds to an input sensitivity of +24dBu for 0dBFS
A value of +20.0 dB corresponds to an input sensitivity of +4dBu for 0dBFS
A value of +66.0 dB corresponds to an input sensitivity of -42.0dBu for 0dBFS
Mic (M) or Line (L) Switches the Input from the Mic-Pre amplifier to the Line level circuitry. The
button will show the current input signal path it is set for (Mic or Line).
The Line input sensitivity can be adjusted by setting the line gain for each input
of the AD module.
Line Fader of 0 dB, means 0 dBFS for +24 dBu Analog signal level present at
the Line input
Line Fader of + 6 dB, means 0 dBFS for +18 dBu Analog signal level present at
the Line input
Line Fader of + 20 dB, means 0 dBFS for +4 dBu Analog signal level present at
the Line input
Line Fader of + 66 dB, means 0 dBFS for -42 dBu Analog signal level present
at the Line input
Note #1: the MIC and Line inputs are stored as independent parameters,
meaning that switching from Mic to Line and vice versa will load its own gain
(sensitivity) value
Note #2: The Premium AD converters of Hapi have been designed in order to
be able to benefit from the +3.1 dB SA-CD headroom offered by DSD, as per
the scarlet book standard. Therefore a minimum of +6 dB gain is required on
the mic preamp or line input. This gain is applied immediately when the ADs
are switched to DSD (64, 128, 256FS) and is visible in the preamp page. The
gain can be adjusted between +6dB and +66dB in DSD mode. In Line mode,
with a gain of +6dB, an input of +24dBu will generate a signal of +6dB SA-CD,
in Mic mode, with the same gain, an input of +13dBu would generate a signal
of +6dB SA-CD.
To benefit also from this +6dB headroom in DSD on the DA outputs of Hapi,
we recommend our users to set the level alignment to -6dB on each DA
module configuration page.

48V This button will turn on 48V phantom power for the channel. If it is lit, it means
that Phantom power is active. Only active on channels set to Mic.
If a MAJOR (by MAJOR, we mean that the threshold of short-circuit detection
requires at least 10 Preamp inputs to be shorted simultaneously) 48V Phantom
Power Supply short circuit is detected, 48V is forced off on all A/D channels
and the following error message is displayed.
“48V power failure: all A/D 48V forced off until next reboot”
This warning applies ONLY to the initial RUN 3 production batch of AD8 and AD8P and has been
fixed for all modules shipped starting November 2012:
The 48V power MUST be turned off prior to changing the connection in certain patch bays. Many
such patch bays do short the Hot, Cold or both signals to Ground during insertion or removal of the
Jacks with the risk of deteriorating permanently the protective resistors in the input of the PreAmp
circuitry. If an AD module input circuitry is damaged, following such a short, it will end up
permanently having inaccurate gain levels, distortion or even no signal at all on some channels.
That would require hardware replacements at your own cost, since such damage is not covered by
our warranty.
If you still own one of the original and unmodified RUN 3 AD8/AD8P modules we recommend that
you contact your Merging reseller to organize an update of your module(s), which Merging is
pleased to provide free of charge.

Note: The available Sampling Rates depend on the Hapi Analog module cards.
Only Premium Analog modules offer support beyond 192 kHz.
Auto Auto Sampling Rate mode. Hapi will automatically follow the sampling rate
given by a RAVENNA source (provided by ASIO / Core Audio Driver,
MassCore or another Horus/Hapi) or external Input Sync source.
Example 1: User using an external player (such as jRiver) can enable the Auto
mode so that Hapi automatically changes its sampling rate according to the
media file being played back.
Provided at least one RAVENNA ASIO or Core Audio stream is connected to
an Output of the Horus/Hapi
Example 2: This Auto setting can apply to user running the RAVENNA ASIO or
Core Audio Driver so that Hapi adapts its sampling rate automatically.
Provided at least one RAVENNA ASIO or Core Audio stream is connected to
an Output of the Horus/Hapi
Example 3: Another usage of this « Auto » sample rate button is to enable the
Horus/Hapi locked (e.g. WordClock) to automatically follow the sample rate of
the WordClock generator (same applies to AES/MADI/ADAT sync).
Provided at least one RAVENNA ASIO or Core Audio stream is connected to
an Output of the Horus/Hapi
Warning: The Auto sampling Rate option must be disabled if locking the
Horus/Hapi devices to reference (e.g. 44.1kHz WordClock) which would be
different than the working Sampling Rate Format (E.g. 88.2kHz,,192kHz,

Latency: The Hapi has 4 Latency Settings (in samples) that will determine the device
latency over a RAVENNA network. When multiple RAVENNA devices (e.g.
Horus & Hapi) are connected over a network, they adjust themselves to the
lowest latency that can globally be achieved.
- Ultra Low (16 smp)
- Extra Low (32 smp)
- AES 67 (48 smp)
- Low (64 smp)
Terminations: 75Ω for WCK: Sets 75Ω termination for the Wordclock Input. Enabling this will
disable the Wordclock output.
75Ω for Video: Sets 75Ω termination for the Video reference Input. Unless the
Video Reference signal provided to the Hapi is daisy-chained to other
equipment, you should always terminate your Video signal for most reliable
operation.
Badge: Dim active will darken the Hapi display luminosity. When active this saves
some power and hence some internally generated heat.

Device Name: Name of the Hapi unit. This name will be broadcast across the network and will
be seen in applications such as the MT Discovery tool. The Hapi unit name can
be changed from the Web control access Network page (see section below for
all details)
IP Settings: Manual: Type IP address using box selection and the - or + buttons
Auto: The IP address will be automatically attributed using ZeroConf/Auto-IP
mechanism (address range 169.254.xx.xx if no DHCP server is present)
Address: Set the IP Address for the Hapi unit by using box selection and the - or +
buttons (Available only with IP Settings = Manual)
Netmask: Set the Subnet Mask for the Hapi unit by using box selection and the < or >
buttons (Available only with IP Settings = Manual)
Apply & Reboot: Once changes have been made to this section, you must press this button to
save the settings and power cycle the Hapi unit
Note:
Hapi has no DHCP-server capability neither does the Merging PCIe Ethernet
Controller Card NET-MSC-GBEX1.
By default the Hapi IP setting is set to “Auto” configuration mode which gives
an address in the range 169.254.xxx.xxx if no DHCP server is present on the
network. Users are free to put a DHCP server in their RAVENNA network with
a customized address range and the Hapi would get an IP address from this
server. Note that our recommended Dell PowerConnect 2816 RAVENNA
switch is configured with DHCP disabled.
Merging recommend the Hapi to be configured in “Auto” mode and the Merging
PCIe Ethernet Controller Card NET-MSC-GBEX1 to also be configured with
“Internet Protocol Version 4” with “Obtain an IP automatically”.
You must be aware that when the Hapi is started in Maintenance mode the IP
configuration is exclusively done using “Auto” IP settings mode.
Info (Setup):
In this sub menu you will find details about the Hapi internals; current consumption, voltage,
temperature, fan speed, serial number and the firmware version currently installed.
