Product Overview
The NetlinkTM FRX4000 is used to provide concentration and access
to remote devices. Each FRX4000 supports up to eight serial inter-
faces. (The FRX6000 isgenerally used where more than eight serial
interfaces are required.) The FRX4000 provides local and remote
switching, and (on devices with video interfaces) features an intu-
itive, menu-based management structure that allows complete local
and remote control of other Cabletron frame relay devices in the
family ofFRX4000,FRX6000, SmartSwitch 1800, and 9W004.
Detailed product descriptions can be found in the Netlink FRX4000/
FRX6000 User Guide.
AbasicFRX4000 containsfour serialports forconnection toa frame
relay or X.25network,user devices, and/or other Cabletron frame
relay devices (FRX4000, FRX6000, SmartSwitch 1800, 9W004).
Each FRX4000 also contains one LANinterface, either Ethernet or
Token Ring. An optional serial expansion card offers four more
WAN ports.
Figure 1-1 I/O Ports on theFRX4000
The main board on the FRX4000 supports four serial
ports. If the CSU/DSU port is used, WAN port 1 is dis-
abled.
I/Ocables are available for WAN ports 0–7 in several configura-
tions, described in Appendix A.

LAN Interfaces
The Ethernet model of FRX4000 contains an Ethernet interface, pro-
videdin RJ-45 (fortwistedpair) and15-pin“D” (AUI, for Thicknet)
configurations. The Ethernet cable and, if AUI, the tranceiver, must
be provided by the customer.
The Token Ring model of FRX4000 contains a Token Ring
interface, provided in RJ-45 (for unshielded twisted pair) and 9-pin
“D” (for shielded twisted pair) configurations. A Token Ring cable,
Cabletron number FRX-TR-CAB, is available.
Operator Interfaces
The FRX4000 doesnot require anyoperator intervention for normal
operation. However, a keyboard and video device are necessary for
initial configuration, and can be helpful later for monitoring.
Each FRX4000 is shipped with cables that allow connection to an
ASCII terminal by any of three methods: direct connection to ter-
minal, connection to terminal via modems, or direct connection to
PC running terminal emulation software.
A keyboard and video device can also be connected via one of these
methods:
●ASCII terminal/keyboard (or PC with terminal emulation
software) connected to an async PAD portin the local
FRX4000.
●ASCII terminal/keyboard (or PC with terminal emulation
software) connected to an async PAD portin a remote
Cabletron frame relay device (FRX4000, FRX6000,Smart-
Switch1800,9W004),through anetwork,into anX.25portin
the local node.
●Keyboard and videodeviceon aremoteCabletron framerelay
device.

Product Overview 1-3
Remote monitoring and configuration of any FRX6000
with IP and SNMP configured can be performed via
Cabletron’s Spectrum network management platform, or
via a Hewlett Packard® workstation with HP OpenView
and Netlink OmniView.
An async terminal’s keyboard must have [F1]–[F10] function keys as
well as [PgUp] and [PgDn] keys.
Standard PC keyboard function keys are represented as follows on a
VT100. (^[ is[Esc], and the followingcharacteris anuppercase letter
O.)

Diagnostic Procedures
All of the procedures in this chapter require an attached
video device.
Once an FRX4000 is operational, much diagnostic information is
availablethrough menu-leveloperations (described in the Netlink
FRX4000/FRX6000 User Guide). However, some problems might
arise that do not readily identify themselves through system error
messagesorobviouschangesin operation. Thischapter describesthe
procedures for verifying correct configuration and operation of an
FRX4000. It also provides some guidelines for pursuinga solution if
there is aproblem.
When an FRX4000 is switched on, the following should occur:
●The fan(s) and the power light on the front panel will come on.
●As the software is loaded, messages will be displayed.
If there are problems during boot-up, error messages will be dis-
played, and the process will continue after the message has been dis-
played for a short time (so watch the screen carefully).
Once the software has correctly loaded, a screen similar to the fol-
lowing will be displayed.

It can probably be asssumed that if you are reading this chapter, the
node did not boot correctly as described. The remainder of this
chapterdescribes steps foridentifying and fixing someproblems.
Certain problems may beeasy to track down; for example:
●If there seems to be no power at all, check to make sure the
powercord issecurely connected atbothends and thatthere is
power (of the appropriatevoltage) at the receptacle.
●If the screen messages are obvious, take the appropriate
action.
●If there is an obvious problem with one or more hardware
components, go to Chapter 3.
Ifthe problem isunclear, review the remainder ofthismanual.If nec-

Reviewing Boot Messages
Asan FRX4000boots, screeninformationverifies configuration file
format, and displays any errors. This data is displayed only until the
FRX4000 software is running; however, it is saved in a file named
BOOTRPT.TXT, and theoperator canlater display itin a report. This
can be used as a tool to verify that startup of the node proceeded
withouterrors. If there isan error reported, the data may aidin fixing
the problem.
If a node is shut down, then rebooted, the existing BOOTRPT.TXT
filewill be renamed BOOTBAK.TXT, and a newBOOTRPT.TXTwill
be created. BOOTRPT.TXT and BOOTBAK.TXT can be used as
follows:
1. Displayandreview thedatafromthe“current”bootof thenode.
2. Address any reported problems.
3. Re-boot thenode.(This copies the previous boot data to a
backup file.)
4. Display the new boot data, and compare it to the previous data.
This will show whether the problem was fixed. Also, a problem
that occurred during the previous boot-up will often be cleared
up by re-booting.
To displaythedata fromthecurrentboot-up,press[C] at the Reports
menu(or [F], then[C] from the Main Menu). Todisplaythe data from
the previous boot-up (saved in a file called BOOTBAK.TXT), press
[D]at the Reports menu (or [F],[D] from the Main Menu).

Diagnostic Procedures 2-5
Boot Messages
Many boot messages are “normal” messages,andare described here
simply for information. Others are error messages, and include rec-
ommended action. After taking the recommendedactionforan error
message, rebootthe node. If the problem has not been corrected,
contact Cabletron Systems Technical Support.
Boot messages are listed below in alphabetical order.
Boot Time: nn/nn/19nn–nn:nn:nn
Meaning: This is the date and time of the current boot-up.
Action: None.
Buffers: Xmt count “n,” Xmt size “n,” Rcv count “n,” Rcv size “n”
Meaning: These values denote the numbers and sizes of the
pre-fetch buffers used by the LANinterface.
Action: None.
Checking configuration files
Meaning: Self-explanatory. The software checksto make sure
all files are valid.
Action: None.
Community Table file Read Error, System may not Boot Correctly
Meaning: There is a error in the database fileCOMPAR.DAT.
Action: Delete the file and create a new one by configuring
new SNMP Community Table records (described
in the User Guide).
Conversion Error
Meaning: The database file specified in the message dis-
played before this one (see Converting (FILENAME)
file ...) was not successfully converted to the new
releaseofFRX4000 software.
Action: Ifthe file is X25REC.DAT(nodeparameters),anew
default file will automaticallybe created.If anerror
occurs in any other file, delete the file and create a

2-6 FRX4000MaintenanceGuide,Rev 03
new one by configuring new records for that file
(described in the User Guide).
Conversion Successful
Meaning: The database file specified in the message dis-
played before this one (see Converting (FILENAME)
file...) was successfully converted to the new
releaseof FRX4000 software.
Action: None.
Converting (FILENAME) file ...
Meaning: The software is converting the specified file from
the earlier release of FRX4000 software to the new
release. (This happens during migration to anew
release.) The number of database files that exist
depends on the configuration in the earlier release.
Action: None.
Creating X25rec.dat file ...
Meaning: This message will follow Conversion Errorif that
error occurs during conversion of the node param-
eters file (X25REC.DAT).
Action: None—a new X25REC.DAT will be created auto-
matically.
Database Error: ERRMSG.TXT Invalid Size
Meaning: The event message file (ERRMSG.TXT) was cor-
rupted during migration to a new release.
Action: Copy ERRMSG.TXTvia file transfer ([B], [A], [B]
fromtheMainMenu—describedinthe UserGuide)
from a remote FRX4000 or FRX6000.
Database Error: X.25REC.DAT Not Present, Expects (current release)
Meaning: The database is missing the node parameters file
(X25REC.DAT). During boot-up, if this file is
missing, a new one is normally created automati-
cally. Failure to create this file indicates a serious
failure in the migration software.

Diagnostic Procedures 2-7
Action: Contact Cabletron Systems Technical Support.
Database Initialization Error: ERRMSG.TXT not found
Meaning: The file ERRMSG.TXTcontains all the event mes-
sages, and must be present in the software, but it is
missing.

fromthe Main Menu—describedin the UserGuide)
from a remote FRX4000 or FRX6000.
Database Release “n” Matches Software Release, No Conversion
Necessary
Meaning: Self-explanatory.
Action: None.
Database Validation Error: Version “n.nn”, Expected (current release)
Meaning: The version of the database is incompatible with
that of the operating system. The FRX4000 will
save the database and open a new blank database.
Action: Check all database records (accessible under
Database operations from the Main Menu, and
described in the User Guide) for proper configu-
ration, and reconfigure where necessary.
Database Validation OK: Version “n.nn”
Meaning: The version of the database iscompatible with that
oftheoperating system.
Action: None.
Data Error: SubID “n” Skipped
Meaning: A subscriber ID in the Remote Subscriber file
