1 Overview

The Ethernet Interface on the SynQor MPS-4000 products adds a web interface and an SNMP interface
for control, configuration, and reporting. This guide provides information regarding initial setup and
functionality of the network interfaces.

The web interface provides a dynamically updated set of pages for user interaction. The SNMP interface
exposes the RFC-1628 standard UPS-MIB interface.

2 Initial Configuration

In order to facilitate connecting to the web interface, the MPS network interface provides multiple
methods to identify the MPS on the network. The user must load the web interface to enable or
configure the SNMP interface.

2.1 DHCP Server

The MPS network interface will recognize a DHCP server on the network and use the IP address assigned
by the server. A network administrator can register the MAC address of the network interface with the
DHCP server to assign the MPS to a static IP address. The MAC address can be read in two ways: (1) via

the RS232 serial command “NETWORK?”; and (2) via the web interface, assuming a connection is made

before the static IP address is assigned (see below).

Once a DHCP server assigns an IP address to the MPS, the web interface can be loaded by pointing a
web browser to the address http://x.x.x.x/, where “x.x.x.x” is the assigned IP address.

2.2 NetBIOS Hostname

The MPS network interface will use NetBIOS to advertise its hostname to the local network. The default
hostname is “SYNQORMPS”. If an IP address is assigned via a DHCP server and NetBIOS is permitted on
the local network, directing a browser on the network to http://synqormps/ or https://synqormps/ will
load the MPS web interface.

Once an initial connection is made to the web interface, the user should assign a unique hostname on
the Network tab (see below), so that the name does not interfere with other SynQor MPS devices on the
network.

2.3 Local Connection

The MPS network interface can connect to a host computer directly via an RJ-45 Ethernet cable. Either a
straight-through or crossover type cable can be used. In this mode, the web interface is available via the
address http://169.254.1.1/. The MPS implements its own DHCP server which will provide an IP address
on the 169.254 subnet to the host computer. Once a connection is established in this way, the user can
configure the default IP address and hostname as desired, as well as read the MAC address for the
purposes of assigning a static IP address.

3 Web Interface

The web interface provides a portal to monitor, control, and configure the MPS. Some of the
configuration options, such as those to setup the email and SNMP interfaces are only available through
the web interface. The interface will work well through any common web browser, though different
browsers may render with slight differences. The pages rely on Javascript to do continuous updates and
submit forms, so scripting must be enabled in the browser. Older browser versions may not support
some of the methods used.

Unsecured HTTP requests are processed at port 80. Secure SSL HTTPS requests are processed at port

443. SSL connections utilize encryption to protect data passed between the MPS and the browser from
snooping. Upon initiation of an SSL connection, the MPS will provide a Certificate to the browser to
verify its identity. The Certificate served will be a “self-signed” certificate, and the browser will warn
that the site is untrusted and request confirmation that you want to continue.

To avoid the warning message on future connections, use facilities in most browsers to mark the MPS
Certificate as a trusted certificate. Note that the certificate includes the NetBIOS name as the
“common-name” as part of its verification criteria, so the certificate is rebuilt after a change to the
NetBIOS name (Section 3.3.1). The browser verifies, and may enforce, that the name in the address bar
matches the common-name in the certificate. If a static IP address (e.g. https://20.1.1.24/) is used to
connect to the MPS, NetBIOS can be disabled and the hostname set to the fixed IP address (e.g.

20.1.1.24) to build a certificate with a common-name that matches the loaded address, avoiding a
browser security error.

SSL certificates specify a date range for validity. The web browser may or may not allow access if the
access date is outside the validity window. The certificates generated by the MPS have validity range
extending twenty years from the date of certificate generation. In order to force certificate
regeneration (and hence create a new validity window), change the NetBIOS name and then change it
back to the desired value. Times and dates used for the certificate are based on the SNTP time server,
see Section 3.3.4.

When SSL is used, the interface can be locked with a username and password, see Section 3.3.5.

The web interface can be disabled completely, see Section 3.3.6.

3.1 MONITOR Page

The Monitor page is the default page shown when you point the browser at the MPS with no page
specified. This page gives an overview of monitored parameters and configuration. The items that are
displayed vary based on the installed options. For example, if the MPS does not have the auxiliary DC
output option installed, the auxiliary DC output parameters will not appear.

Figure A Monitor Page of Web Interface

The Monitor page (as well as all other pages) has a flashing green dot in the top right of the title bar
which indicates that there is a connection to the MPS and the displayed data is continuously updated. If
the connection is broken, the dot will turn red to indicate stale data.

3.2 CONTROL Page

The Control page is the main page to use to interact with and configure the MPS. There is a small
header section at the top which actively updates to give the present configuration and operational state.
Actions available to interact with the MPS:

 Enable and disable the MPS Output

 Turn on and off Battle Mode

 Run fan diagnostics

 Manually set fan speed

 Set unit to reboot the output after a designated off time

 Set the unit to shut down the output after a designated delay

 Set the unit to enable the output after a designated delay

 Abort a pending startup or shutdown delay

Configuration options available on the Control page are:

 Set / clear auto-start option for automatic startup when power is applied

 Disable automatic operation of fan diagnostics

 Set auxiliary output to enable or disable with the main output

 Enable or disable multi-unit on / off synchronization control

 Enable or disable multi-unit fault shutdown synchronization control

 Adjust input current limit parameter to avoid tripping external breakers rated below 30 A

All actions taken on the Control page take effect immediately. The Configuration options are stored to
non-volatile memory. Note that the commands will be acknowledged on the serial interface just as if
they were entered through the serial interface.

3.3 NETWORK Page

The Network page offers options to configure the MPS on the network. Changes on this page do not
take effect until the user presses the Apply button at the bottom of the page. Configuration changes are
stored in non-volatile memory. A status window at the top of the page shows the present configuration
on the network.

3.3.1 NETBIOS

NetBIOS is a protocol that allows a device to register a default hostname on the network. With this
hostname, a user can address a device without knowing the assigned IP address. By default, the MPS is
configured to register the hostname “SYNQORMPS”. The user has the option to disable NetBIOS, in
which case they would need the IP address assigned to the device to use the web interface. The IP
address could instead be assigned to a static address by the router based on the MAC address.

When the NetBIOS name changes, the MPS rebuilds the SSL Certificate that will be served to browsers
connecting to the web interface via an SSL (https://) connection.

3.3.2 ADDRESS RESOLUTION

DHCP is a protocol which allows the router to assign an IP address to a device on the network. By
default, DHCP is enabled and the MPS will be assigned an IP address by a service on the network. A
DHCP-assigned address has an expiration time (lease). The MPS will attempt to renew its DHCP lease
before it expires. When DHCP is disabled, the MPS reverts to the default IP address specified. In this
situation, the MPS will transmit DHCP discovery requests once per minute to determine if a DHCP host is
present on the network.

AutoIP is an alternate IP address assignment protocol. With AutoIP, the device starts using a particular
address and observes if there are any conflicts. By default, AutoIP is disabled, and DHCP is the
recommended address resolution protocol.

The Local DHCP Server option allows the MPS to hand out addresses over a local network, such as when
the MPS is directly connected to a computer’s Ethernet port. When this option is disabled, the MPS
does not respond to DHCP requests and the DHCP discovery requests are halted. The MPS will not
respond to DHCP requests if it detects that a DHCP server is present on the network.
