good source of information that may be used remotely to provide pre-

liminary diagnostic information, or may even provide a path to cor-

recting the problem.

Table 7-3. Basic Troubleshooting with the entraNET MS

Symptom Problem/Recommended System Checks

Remote does not

connect

a. Verify the AP has sufficiently large number in the “Max

Remotes” parameter of the Network Configuration Menu.

b. If “Approved Remotes” is enabled on the Security

Configuration menu (at the AP), verify the correct serial

number is listed in the Approved Remotes List.

c. On the Remote, if “Restrict” is turned on in the APLIST

command, verify the Access Point is included in the list of

Approved APs.

Cannot access the

entraNET AP Menu

(through COM1)

a. If the unit is an AP, connect via Telnet or Web browser

b. Disable the serial mode for COM1

(Serial Gateway Configuration>Com1 Serial Data

Port>Status>Disabled)

Or, if you know the unit’s data configuration:

a. Connect to COM 1 via a terminal set to VT100 and the

port’s data baud rate.

b. Type “+++ [ENTER]”

c. Change the terminal’s baud rate to match the transceiver’s

Console Baud Rate.

d. Type “+++ [ENTER]”

Cannot access the

Remote’s

command interface

a. Connect to the AP’s menu and manage the Remote via the

Serial Configuration menu. Check the configuration for

COM1 or 2, as applicable.

Display on

terminal/Telnet

screen garbled

a. Verify the terminal/terminal emulator or Telnet application

is set to VT100. Restart terminal program.

Cannot pass IP

data to WAN.

a. Verify the AP’s IP settings.

b. Use the PING command to test communication with the AP

and endpoints connected to Remote radios in the local

radio system.

c. If successful with local PING, attempt to PING an IP unit

attached to a radio.

d. If successful with the LAN PINGs, try connecting to a

known unit in the WAN.

Wireless Retries

too high.

Possible Radio Frequency Interference—

a. If omnidirectional antennas are used, consider changing to

directional antennas. This will often limit interference to and

from other stations.

b. Try skipping some zones where persistent interference is

suspected or packets-per-zone are disparate.

c. The installation of a filter in the antenna feedline may be

necessary. Consult the factory for further assistance.

Password

forgotten.

a. Connect to the transceiver using a terminal through the

COM1 Port.

b. Call MDS. Get a password-resetting Authorization Key.

c. Enter the Authorization Key at the login prompt as a

password.
