Q
|
What is the difference between the EasyServer II and the LantraServer?
|
|
A
|
Both the EasyServer II and the LantraServer are
fully-featured communications servers designed for TCP/IP networks. The
EasyServer II supports devices such as terminals, printers and modems and can
be used for remote access (PPP, SLIP), inter-office communications and other
serial-connectivity applications. The EasyServer II supports RADIUS and
dial-on-demand routing. Also, with the advent of TruPort for UNIX, the
EasyServer II can now be configured with devices and real tty's using the
Stallion "easyadm" software familiar to users of EasyIO and
EasyConnection. TruPort provides real UNIX serial devices, supporting the
fullest range of devices and applications.
The LantraServer, in conjunction with the Extend software for Windows NT allowed
the serial ports of the LantraServer to be used as Windows NT COM ports
anywhere on the network. This provided flexible communications in many
applications including Windows NT routing and remote access services, faxing
and modem pooling. The LantraServer also does everything the EasyServer II can
do.
As of firmware version 6.2.0 in the EasyServer II and version 1.2.0 of Extend,
all the specific LantraServer functionality is now supported by the EasyServer
II and the LantraServer was discontinued as a separate product.

Q

Ethernet? |
|
A
|
No, the current EasyServer II does not support fast
Ethernet. Future models in production will support 100Mbps networking
technologies.

Q
|
The RCV, XMT and NET lights are flashing together on
the front of my EasyServer II and the power LED is on. What does this mean? |
|
A
|
When these LEDs flash together at a frequency of once
per second and the power light is on, the EasyServer II or LantraServer is
asking for an IP address to be configured in the unit. This is normal and new
units will do this the first time they are turned on. Existing operational
units will do this if they have been factory reset or if their non-volatile
memory has been erased.
To stop the flashing, configure an IP address in the unit.

Q
|
I connected a modem to an EasyServer II port but the
modem doesn't answer the incoming call. What is wrong? |
|
A
|
There are several things you should check:
-
Check the configuration of the modem. Try resetting the modem to the factory
default (using an AT&F modem command) and then setting the modem to
auto-answer the incoming call (using a modem command like ATS0=1).
-
Ensure the cable between the modem and EasyConnection port is wired correctly
as a full modem cable. Check the user manual for cable details.
-
Check if DTR has been asserted by the EasyServer II by using a RS232 tester or
by using the command MONITOR PORT <port_number> STATUS.

Q
|
What is the maximum speed supported by an EasyServer
II serial port? |
|
A
|
All of the EasyServer II serial ports support a
maximum speed of 230400 bps. Almost all serial devices use interface
speeds of 115200 bps or less. Usually speeds of up to 230400 bps are only
used by terminal adapters or CSU/DSU devices (in ISDN equipment, for instance).

|
Q
|
Can I upgrade the firmware of the EasyServer II or
LantraServer? |
|
A
|
Yes, if the EasyServer II or LantraServer you have
supports flash memory upgrade. Generally speaking, if your unit has a
firmware version of 5.x.x then the unit does not support flash memory upgrade.
If the unit has a firmware version of 6.x then the unit does support
flash memory upgrade. Units that do not support flash memory upgrage can
be returned to Stallion Technologies for a hardware upgrade to support flash
memory for a small charge.
To determine the version of the firmware in your current unit, log into the
unit and run the SHOW SERVER command. This will display the firmware
version.
