Terminology and Conventions

This typeface represents general text. This typeface represents computer

input and output.

In on-screen versions of the manual, items in blue are links to other places

in the manual.

v

This symbol points to an informational note relating to the text,

table, or figure that immediately precedes or follows it.

This symbol and text identifies a cautionary note, the

content of which is more critical to heed than an informa-

tional note.

This symbol and text identifies a warning, intended to

prevent either injury to the user or major damage to

hardware, software, or system operation.

References to these keyboard keys appear in the manual and/or on the

screen:

"[N]"

—

is a reference to a key on your keyboard (where “N” is the key).

"Enter"—means that you should type in the information, then press the

[Enter] key.

"Type"—is similar to "Enter", except that the word “[E nte r]” follows

the information to be typed (e.g., "type n [Enter]").

"Press"—means press (hit, strike) the key once. Pressing the [E nter]

key afterwards is not necessary.

"[Ctrl]"

—

followed by one or two other key designations, must be struck

simultaneously with the other keys shown.

If a statement ends with a reference to a key—for example, “....then press

[Enter].”—the period is not part of the data to be entered. If a period should

be entered, it will be shown as "[.] ." The same applies to all other punctu-

ation.

When instructed to, for example, “press [A], [B] from the Main Menu,” this

means press [A], then [B], not [A] comma [B].

Screen displays are provided to show the general appearance of

actual screens. They are only examples—they do not neces-

sarily represent an operational system.

Product Overview

The Netlink

TM

FRX4000 is used to provide concentration and access

to remote devices. Each FRX4000 supports up to eight serial inter-

faces. (The FRX6000 is generally 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 of FRX4000, FRX6000, SmartSwitch 1800, and 9W004.

Detailed product descriptions can be found in the Netlink FRX4000/

FRX6000 User Guide.

A basic FRX4000 contains four serial ports for connection to a frame

relay or X.25 network, user devices, and/or other Cabletron frame

relay devices (FRX4000, FRX6000, SmartSwitch 1800, 9W004).

Each FRX4000 also contains one LAN interface, either Ethernet or

Token Ring. An optional serial expansion card offers four more

WAN ports.

Figure 1-1 I/O Ports on the FRX4000

The main board on the FRX4000 supports four serial

ports. If the CSU/DSU port is used, WAN port 1 is dis-

abled.

I/O cables are available for WAN ports 0–7 in several configura-

tions, described in Appendix A.

Ports 4–7 are on optional

expansion module

LAN Interfaces

The Ethernet model of FRX4000 contains an Ethernet interface, pro-

vided in RJ-45 (for twisted pair) and 15-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 does not require any operator 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 port in the local

FRX4000.

●

ASCII terminal/keyboard (or PC with terminal emulation

software) connected to an async PAD port in a remote

Cabletron frame relay device (FRX4000, FRX6000, Smart-

Switch 1800, 9W004), through a network, into an X.25 port in

the local node.

●

Keyboard and video device on a remote Cabletron frame relay

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

Diagnostic Procedures

All of the procedures in this chapter require an attached

video device.

Once an FRX4000 is operational, much diagnostic information is

available through menu-level operations (described in the Netlink

FRX4000/FRX6000 User Guide). However, some problems might

arise that do not readily identify themselves through system error

messages or obvious changes in operation. This chapter describes the

procedures for verifying correct configuration and operation of an

FRX4000. It also provides some guidelines for pursuing a solution if

there is a problem.

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.

Diagnostic Procedures 2-3

Figure 2-2 Main Menu

It can probably be asssumed that if you are reading this chapter, the

node did not boot correctly as described. The remainder of this

chapter describes steps for identifying and fixing some problems.

Certain problems may be easy to track down; for example:

●

If there seems to be no power at all, check to make sure the

power cord is securely connected at both ends and that there is

power (of the appropriate voltage) 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.

If the problem is unclear, review the remainder of this manual. If nec-

essary, contact Cabletron Systems Technical Support, at:

Reviewing Boot Messages

As an FRX4000 boots, screen information verifies 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 the operator can later display it in a report. This

can be used as a tool to verify that startup of the node proceeded

without errors. If there is an error reported, the data may aid in fixing

the problem.

If a node is shut down, then rebooted, the existing BOOTRPT.TXT

file will be renamed BOOTBAK.TXT, and a new BOOTRPT.TXT will

be created. BOOTRPT.TXT and BOOTBAK.TXT can be used as

follows:

1. Display and review the data from the “current” boot of the node.

2. Address any reported problems.

3. Re-boot the node. (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 display the data from the current boot-up, press

[C]

at the Reports

menu (or

[F],

then

[C]

from the Main Menu). To display the 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, and are described here

simply for information. Others are error messages, and include rec-

ommended action. After taking the recommended action for an error

message, reboot the 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 LAN interface.

Action: None.

Checking configuration files

Meaning: Self-explanatory. The software checks to 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 file COMPAR.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

release of FRX4000 software.

Action: If the file is X25REC.DAT (node parameters), a new

default file will automatically be created. If an error

occurs in any other file, delete the file and create a

2-6 FRX4000 Maintenance Guide, 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

release of 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 a new

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 Error

if 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.TXT via file transfer (

[B], [A], [B]

from the Main Menu—described in the User Guide)

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.TXT contains all the event mes-

sages, and must be present in the software, but it is

missing.

Action: Copy ERRMSG.TXT via file transfer (

[B], [A], [B]

from the Main Menu—described in the User Guide)

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 is compatible with that

of the operating system.

Action: None.

Data Error: SubID “n” Skipped

Meaning: A subscriber ID in the Remote Subscriber file

(RSNSVC.DAT) does not exist in the SVC Sub-

scriber file (SVCSUB.DAT), and the remote sub-

scriber record will not be copied to the new

database.

Action: Create a new remote subscriber record (described in

the User Guide).

2-8 FRX4000 Maintenance Guide, Rev 03

File Transfer Abort Error

Meaning: While waiting for a file transfer connection to

become established, an abort was attempted from a

different ID (the one in the message) than that used

to initiate the file transfer request.

Action: The abort must be initiated from the same ID that

was used to initiate the file transfer.

Initialization Error: Can’t Create Line Record/ Status Table

Meaning: There is a severe memory error.

Action: Check all the installed memory for proper seating.

If it is all securely installed, replace each module

and reboot, one at a time.

initLan: Could not allocate recv/xmit buffer “n”

Meaning: There is a severe memory error.

Action: Check all the installed memory for proper seating.

If it is all securely installed, replace each module

and reboot, one at a time.

IP Interface file Read Error, System may not Boot Correctly

Meaning: An error in the IP Interface file (IPISUB.DAT)

occurred during IP initialization.

Action: Delete the file and create a new one by configuring

IP Interface records (described in the User Guide).

IP Routing file Read Error, System may not Boot Correctly

Meaning: An error in the IP Routing file (IPRSUB.DAT)

occurred during IP initialization.

Action: Delete the file and create a new one by configuring

IP Routing records (described in the User Guide).

No remote subscribers for subID “n”

Meaning: No Remote Subscriber records existed in the

database for the specified SNA subscriber (

subID

).

Action: Delete the SNA Subscriber record or create Remote

Subscriber records.
