(APPENDIX A) DEVICE MANAGER USER INTERFACE
Introduction
The Relay2 Access Point (AP) starts functioning without preconguration under typical
network condition. The AP is able to connect to the Relay2 NMS when the following
prerequisites are met:
• The DHCP server is reachable, and the AP can get an IP address.
• The AP is able to reach the DNS server.
• The AP is able to send https packets to the internet directly.*
• Uplink packet, MTU = 1500, from the AP is accepted by the network.
• The L2 packet is accepted by the network without VLAN tagging.
In case any item in the list above is not supported—which is a special environment for
Relay2 AP and requires manual preconguration—this document shows the procedure of
such manual conguration through the Relay2 Device Manager UI.
The procedure in this document shows the example of the minimal environment in which
the AP is only connected to a PC.
*No proxy between AP and NMS
Preparation
This section shows the preparation for the manual conguration.
Hardware
The required hardware for the conguration is listed below:
• Relay2 AP to congure
• AC adapter or POE+ connection
• PC (web browser used for the conguration)
• LAN cable (with RJ45 connectors)
• Ethernet hub (in case it is necessary to connect the AP and PC via the hub)
Additional Information Needed
The information listed below is used during the preconguration process:
• MAC address and serial number of the target AP (You can nd them on the label at the
bottom of the AP.)
• IP address for the target AP in case conguring AP is executed under a network with a
DHCP server
IP Address of the AP
The IP address of the target AP is used to access DM GUI even at stand-alone.
Link-Local IP Address of RA641
The link-local IP address of the Relay2 AP, 169.254.0.0 network, is calculated from the right
four digits of the AP MAC address. For example, if the MAC address is B4:82:C5:00:6B:E6,
then the link-local IP address of that AP is 169.254.107.230. (i.e., hex: 6B => dec: 107 and hex:
E6 => dec: 230).
IP Address for the PC
The Ethernet port of the AP shall be in the same VLAN for the AP.
In case the PC is connected with the AP directly, the AP assigns the link-local IP address to
itself. Thus, the IP address of the PC shall be the same network.
A normal PC assigns its own IP address in the 169.254 network and in the same manner as
the AP.
Connecting the AP with the PC
DM GUI Step 1: Connect between the AP LAN port and the PC with a LAN cable. Then power
up by connecting the DC power unit to the power connectors.
Conrm that the Ethernet link is active with the LED at the LAN port or the LED on the AP.
• In the case that the AP and PC are connected directly for RA641, both nodes utilize the
link-local IP address with the 169.254.0.0 network.
Accessing the DM GUI
DM GUI Step 2: Access to https://<AP IP address>:9999 with any browser application on the
PC.
E.g., in the case that the AP IP address is 169.254.107.230, then https://169.254.107.230:9999.
Note: Relay2 AP is not registered for CA certication, so a warning message for a privacy
error could be seen upon the rst DM GUI access, like below. Please continue the access.
DM GUI Step 3: In the case of MS Edge, continue by clicking “advanced.”
Figure 2: Advanced window at privacy error (edge)
(Proceed to 192.168.100.54 (unsafe)
at the bottom line)
Figure 1: Example of privacy error (Microsoft edge)
DM GUI Step 4: Click “Proceed to <IP address> unsafe” for the DM GUI page to be shown.
(Refer to Figure 3 below)
DM GUI Login
Fill in the username and password, then click “Login.” At default,
Username: AP mac address without colons (“:”)
Password: AP S/N with capital letters
E.g., MAC address = B4:82:C5:00:7D:DB, S/N = EMP6610100C00617
Username: b482c5007ddb
Password: EMP6610100C00617
If login is successful, the initial page, as below, is shown.
Figure 4: DM GUI initial page
Figure 3: DM GUI login window
Error Case
In case the PC and AP are in different segments, the browser will display a time-out error.
• Please double-check the AP IP address and that there is no typo in the browser input.
• Please check that the PC IP address and AP IP address are in the same VLAN.
• Please check that there is no IP address conict in the network.
