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 thekey).
"Enter"—means that you should type in the information,then press the
[Enter] key.
"Type"—is similar to "Enter", except that the word “[Enter]” follows
the information to be typed (e.g., "type n [Enter]").
"Press"—means press (hit, strike)the key once. Pressing the[Enter]
key afterwards is not necessary.
"[Ctrl]"—followed by one ortwo other key designations,mustbe 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 ofthe data to beentered.Ifa period should
be entered, it will be shown as "[.]." The same applies to all other punctu-
ation.
Wheninstructedto, for example, “press [A],[B] from the MainMenu,” this
meanspress[A], then [B], not [A] comma [B].

Hardware Overview
The NetlinkTM FRX6000is used toprovide concentration and access
to remote devices. Each FRX6000 supports up to sixty-four serial
interfaces, and can function as central-site devices for remote
FRX4000s, SmartSwitch 1800s, and/or 9W004s. The FRX6000 pro-
vides local and remote switching, and (on devices with videointer-
faces) feature an intuitive, menu-based management structure that
allows complete local and remotecontrol of other Cabletron frame
relay devices.
Detailed product descriptions can be found in the Netlink FRX4000
&FRX6000 User Guide.

LAN Adapters
An FRX6000 can contain one or two LAN cards (Two Ethernet, or
one Ethernet and one Token Ring).
Figure 1-3 Lan Cards
Operator Interfaces
The FRX6000 does notrequire any operator intervention for normal
operation. However, akeyboard and VGA monitor are necessary for
local software installation, and a local monitor or local/remote asyn-
chronous terminal(via the COM1 port) are necessary for configu-
ration and monitoring.
The async terminal’s keyboard musthave[F1]–[F10] function keys as
well as [PgUp] and [PgDn] keys.

Each FRX6000 is shipped with cables to allow connection to the
device from an ASCI terminal orfrom a PC with terminal emulation.
(See Figure A-9 through Figure A-11.)
A keyboard and video device can also be connected via one of these
methods:
●ASCII terminal/keyboard (or PC with terminal emulation)
connected to an async PAD port in the local FRX6000.
●ASCII terminal/keyboard (or PC with terminal emulation)
connected to an async PADport in a remoteCabletron frame
relay device (FRX6000, FRX4000, SmartSwitch 1800, or
9W004), through a network, into an X.25 port in the local
FRX6000.
●Keyboard and videodeviceon aremoteCabletronframerelay

Remotemonitoring and configuration ofanyFRX6000
with IP and SNMPconfigured can be performed via
Cabletron’s Spectrumnetwork managementplatform, or
viaa HewlettPackard® workstation with HPOpenView
and Netlink OmniView.

Diagnostic Procedures
All of the procedures in this chapter require an attached
VGA monitor. You should alsohave a diagnostic diskette
(suchas CheckIt®)anda bootable 1.4MBblank diskette,
to analyze the system configuration.
Once an FRX6000 is operational, much diagnostic information is
availablethrough menu-leveloperations (described in the Netlink
FRX4000& FRX6000 UserGuide). However, some problemsmight
arise that do not readily identify themselves through system error
messagesorobviouschangesin operation. Thischapter describesthe
procedures for verifying correct configuration and operation of an
FRX6000. It also provides some guidelines for pursuinga solution if
there is aproblem.
When an FRX6000 is switched on, the following should occur:
●The fan(s) and the power light on the front panel will come on.
●BIOS identifying information will be displayed.
●There will be a short beep as memory is tested, and the screen
will display the memory being counted.
●Each disk drive’s access light willcome on as the disks are
searched for the necessary DOS boot files.
●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).

2-2 FRX6000MaintenanceGuide,Rev 03
Once the software has correctly loaded, a screen similar to the fol-
lowing will be displayed.
Figure 2-1 Port Status Display
From this screen, you should be able to log into the Main Menu
(Figure 2-2), which is the starting point for configuration and oper-
ation procedures.

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 appropriate voltage) at the receptacle.
●If there is power but the hardware does not seem to be func-
tioning properly, verify the correct setting of the AC voltage
selector switch. (See Chapter 3.)
●If there is an obvious problem with one or more hardware
components, go to Chapter 3.
●If the node appears to boot correctly but there is a communi-
cation problem with an async terminal, go to "COM Port
Interface Controls" on page 2-20.

Diagnostic Procedures 2-5
Reviewing Boot Messages
As an FRX6000 boots, screen information tracks the loading of
cards, verifies configuration file format,and displays any errors.
This data is displayed only until the FRX6000 software is running;
however, it issaved ina file named BOOTRPT.TXT, and the operator
canlater display it in a report. Thiscan be used asa tool to verifythat
startup ofthe node proceeded without errors,orto remindthe userof
the number and types of RLPs in the node. 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
filewillberenamed BOOTBAK.TXT,anda newBOOTRPT.TXT will
be created. BOOTRPT.TXT and BOOTBAK.TXTcan 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 thenode.(This copies theprevious 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
upby re-booting.
Todisplaythe data fromthe 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).

2-6 FRX6000MaintenanceGuide,Rev 03
Boot Messages
Many boot messagesare “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 at:
Phone: [phone]
FAX: [phone]
E-mail: [e-mail].
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.
Can’t Initialize Memory, “NNN”.CMP
Meaning: There is not enough memory in the FRX6000 to
load the RLP software(if “NNN” is "BOOTUP")or
the VxWorks software (if “NNN” is "VXWORKS").
An FRX6000 has 1 MB of memory, but only the
640 KB of base memory is needed to load and run
the software. If one of these messages isdisplayed,
some of that base memory is faulty.
Action: Check all the installed memory for proper seating.
If it is all securely installed, replaceeach module
and reboot, one ata time.
Can’t open COFF file, “NNN”.CMP
Meaning: Either the compressed boot(if“NNN”is "BOOTUP")
or VxWorks (if“NNN” is "VXWORKS") file handle
could not be foundduring RLP softwareloading.
