Using the MRV

An MRV is a terminal server that provides remote (network) access to serial TTY ports.
TTY ports can be accessed by the following methods:

1. CLI with Telnet:

From a PC, click Start ➤ Run, and enter cmd to open a DOS command window
- many devices provide a telnet command, such as routers and switches
At the command prompt, type: telnet <ip-address> port#
- for example:

> telnet 10.10.10.17 2100      - to connect to MRV serial port #1

The IP-address is the fixed IP address of the MRV, followed by a TCP port number representing the physical TTY port.

The default port numbers are Telnet 2100-6800, SSH 2122-6822. For example:

Port #:	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25	26	27	28	29	30	31	32	33	34	35	36	37	38	39	40	41	42	43	44	45	46	47	48
Telnet:	2100	2200	2300	2400	2500	2600	2700	2800	2900	3000	3100	3200	3300	3400	3500	3600	3700	3800	3900	4000	4100	4200	4300	4400	4500	4600	4700	4800	4900	5000	5100	5200	5300	5400	5500	5600	5700	5800	5900	6000	6100	6200	6300	6400	6500	6600	6700	6800
SSH:	2122	2222	2322	2422	2522	2622	2722	2822	2922	3022	3122	3222	3322	3422	3522	3622	3722	3822	3922	4022	4122	4222	4322	4422	4522	4622	4722	4822	4922	5022	5122	5222	5322	5422	5522	5622	5722	5822	5922	6022	6122	6222	6322	6422	6522	6622	6722	6822

Once you connect to the port, you should have access to the connected device. See also: MRV Ports and Ports.

Note: In a redundant dual core (High-Availability) PBX system, you can access either Core 0 or Core 1 - BUT only one core will be active and allow programming. You will need to split the system in order to access both cores, eg: for upgrades or maintenance.

2. GUI with PuTTY:

Select Telnet, Host Name is the MRV IP address, followed by a Port number representing the TTY port (as above):

3. Web-based GUI interface:

In a browser window, enter the MRV IP address: the LX-Series Console Access page displays.
Click on the Launch Secure Console button.
If Java is correctly installed, a Security Warning window displays.
Accept the Security prompt. The Security Warning window closes.
Enter your Username (InReach) / Password (access), and click Login.
Click the Admin button on the toolbar and enter the Superuser password (system).
You can now configure the unit via the GUI.

4. Remote Modem Access:

You will need to have an analog line installed to the MRV and plugged into the built in Modem. Do the following:

Set hyper-terminal to baud rate 9600, data bits 8, parity none, stop bit 1, flow none, and terminal VT100.
Dial the extension number connected to the MRV
When connected you will see Login, enter ACCESS ↵
Enter the user name: ADMIN ↵
Set Privilege mode: SET PRIV ↵
Enter the password: SYSTEM ↵
Follow the procedures in 1b to Telnet into the ports.
Eg: telnet 10.10.10.17:2100 to connect to device on MRV port #1

Note: when logged into the MRV via dialup, you can see the available commands by typing HELP ↵
