MorphoWave Compact - 2018_2000035853-v81
The PoE+ standard can support devices consuming up to 30W of power. The network switch will detect
automatically that the device is a PoE+ device (802.3at compliant) at power up and provide the required
power so the device can start.
However, the standard also specifies a LLDP protocol that is used after the device is started. The LLDP
protocol is bidirectional and is carried over Ethernet frames. It allows the network switch and the device
to negotiate the amount of power needed by the terminal and the amount of power that the switch is
allocating for the device.
It is important to configure the switch to allocate the proper amount of power for the
MorphoWave SP
so it can work properly.
A typical sign of misconfiguration is that, when a user swipes his hand through the reader, the terminal
will reboot because the switch will refuse to provide the required amount of power.
The MorphoWave SP
will send a LLDP request for 25W and a “Critical” level. The switch shall be
configured to allow the terminal to consume up to 25W of power.
Managed vs non-managed PoE+ switches
Managed switches will tend to control the power distribution in a very precise way and need to be
properly configured but will not overcommit their power supply.
Unmanaged PoE+ switches may be more tolerant about the power distribution and may only limit the
total power distributed. In this case, it is important to evaluate the peak power supply necessary for all
the connected terminals and insure that it does not exceed the power supply of the switch.
Example of PoE+ Switch configuration: HP ARUBA switches 2530-24-PoE+
For the ARUBA switches, two options are possible for the configuration setting:
- Fixed : Allocate 30W for each PoE+ port
This option will limit the number of
MorphoWave SP
terminals connected to the switch because it
will refuse to overcommit its power supply.
The commands to set this configuration are:
(config)# interface X poe-allocate-by value
(config)# interface X poe-value 30
Where X is the port number.
- Usage : Allocate the power dynamically to the device as required
This second option will be more flexible because the devices are unlikely to be consuming the
maximum amount of power at the same time.
The commands to set this configuration are:
(config)# interface X poe-allocate-by usage
(config)# interface X poe-lldp-detect enabled
Where X is the port number.
Date / Time synchronization
The terminal clock has a +/-10 ppm typical time deviation at +25°C (roughly /- 6 sec per 48
hours). At lower and higher temperature (but within normal operating temperatures), deviation may be
more important (worst case: - 14 seconds per 48 hours).
If the terminal is used in an application requiring high time precision, we recommend synchronizing
regularly your terminal time with an external clock (using NTP). Every 24 hours is usually enough for
most applications.
