TM
load host, the ULTRIX operating system V4.2 and
DECnet/OSI for ULTRIX must be installed on the DEC WANrouter 90 system load host.
• DEC WANrouter 90 distribution software must be installed on each DEC
WANrouter 90 system load host.
The distribution software includes a router image file that is down-line loaded over
the Ethernet or the serial line to the DEC WANrouter 90. The load host down-line
loads the router image whenever required, and provides the router image to any number of routers. The router image, running on the DEC WANrouter 90, enables the
router to perform its functions.
NOTE
The DEC WANrouter 90 hardware is configured at the
factory for down-line loading over the Ethernet. Appendix C provides instructions for configuring the router for down-line loading over the serial line.

3.4 Testing the Router Hardware
Plugging in the router power cord, or inserting the router into a powered-up DEChub
90 backplane, applies power directly to the router and causes the router to automatically begin its self-test. The self-test consists of diagnostic routines that test and
verify the operation of the unit. Pass/fail test results are indicated by the router’s
LEDs.
LKG-5966-92I
3–9Installing the DEC WANrouter 90
Page 53
The following sequence of events occur at power up:
1. As soon as power is applied to the unit, the green Power LED is lit.
2. Core tests are run to verify that the router’s data and address registers function correctly.
3. Next, the PROM and DRAM are verified. Following these tests, the remaining logic is tested.
4. The self-test takes approximately one minute. The results of the self-test are
displayed by the unit’s LEDs:
a. If only the Power LED is lit, it indicates that the self-test failed.
b. If the Power LED is lit, and the System OK LED is blinking, it indicates
that the self-test failed, but the core is operational.
c. If both the Power and System OK LEDs are lit, it indicates that the unit
passed its self-test.
5. Upon successful completion of the self-test, the router attempts to down-line
load the DEC WANrouter 90 software image over the Ethernet LAN, from a
suitably configured load host. During this process, both the Power LED and
System OK LED remain lit.
6. If the operational software is successfully loaded, the Network LED is lit and
remains on, along with the Power and System OK LEDs.
7. If the software is not available (for example, if it has not been installed on the
load host, or the load host is not functioning), the Network LED will blink
momentarily and then extinguish.
Table 3–1 summarizes the states of the DEC WANrouter 90 LEDs.

• BC19C-02 — Connects DEC WANrouter 90 to X.21 leased lines
CAUTION
The V.24 to RS-232-C adapter must be fitted between
the adapter cable (BC23V-02, BC19D-02, or
BC19V-02) and the extension cable if the modem/eliminator has:
• A signal with a DCE source on pin 18
• Signal quality implemented on pin 21
• Data signal rate selector (DCE) on pin 21
Failure to comply with this could result in damage to the
interface module and modem or eliminator. If you are
not sure what signals the modem or eliminator provides,
contact Digital Field Service.

Bootline Configuration Program
This chapter describes how to use the Bootline Confguration Program (BCP) to configure the DEC WANrouter 90 for serial line loading.
C.1 Introduction
The Bootline Configuration Program (BCP) allows you to configure the DEC W ANrouter 90 serial port so that software can be down-line loaded to the router over a serial line. Y ou can also use BCP to examine the current parameters of the serial port and
to test the attached modem and cable.
BCP supports the following commands:
• CONFIGURE –– Sets the parameters for the serial port. It can also be used to
change the load protocol.
C
• SHOW –– Displays the current parameters of the serial port, or displays the
selected load protocol.
• TEST –– Performs loopback testing on the serial port and its associated cable
and modem.
• CONTINUE –– Returns the router to firmware control.
C–1
Page 92
The DEC WANrouter 90 is factory preset for down-line loading over the Ethernet.
However, when the serial port is configured for down-line loading, software can no
longer be down-line loaded through the router’s Ethernet interface. To enable the
DEC WANrouter 90 Ethernet interface for down-line loading, you use BCP to
change the load protocol to BOOTP/TFTP, as described in Section C.5.5. When
BOOTP/TFTP is selected, serial port down-line loading is automatically disabled.
C.2 Howto Enter BCP
Enter BCP by pressing Ctrl/B under one of the following conditions:
• When the router passes its self-test and is attempting to load using MOP.
The terminal attached to the router’s console port will show one of the following messages:
Init –1101– Attempting to locate load host, [IS08802]
Init –1 101– Attempting to locate load host, [ETHERNET]
Init –1 100– Requesting load on serial line
Init –1 103– Router will retry operation in n seconds
• When the router passes the self-test and is attempting to load using BOOTP/
TFTP.
Only when the terminal displays the following message can BCP be entered
using Ctrl/B:
Init –1314– Router will retry operation in n seconds
• When prompted by the screen display:
Init –1004– Enter Ctrl/B to enter BCP
This prompt occurs when neither the serial port or Ethernet interface have
been enabled to load the software, or the enabled port has failed self-test.
• When prompted by the screen display:
Init –1003– Enter Ctrl/P to repeat self-test or enter Ctrl/B to enter BCP
This prompt occurs when the Ethernet port has been enabled to load the software but fails self-test and the serial port is not available for loading.
C–2 DEC WANrouter 90 Owner’s Manual
Page 93
If the router is trying to load over the serial line, when you type Ctrl/B, there is a delay
of approximately five seconds and the following message is displayed:
Init –1 122– Entering BCP, please wait
C.3 BCP Commands
The following subsections describe the BCP commands and the last subsection describes how to abort a command.
C.3.1 CONFIGURE Command
Use the CONFIGURE command to:
• Select MOP or BOOTP/TFTP for downline loading.
If BOOTP/TFTP is selected, then the router only attempts to load over the
Ethernet.
• Enable/disable downline load over the Ethernet.
If downline loading over the Ethernet is disabled, the BCP program will inform the firmware and the firmware will only attempt to downline load
through the serial port.
• Set the node password for the router.
This password is used by the router to accept or reject information. This password is set by the network manager.
• Set the serial port parameters.
Table C–1 shows the serial port parameters.

C.3.2 SHOW Command
Use the SHOW command to:
• Display the selected load protocol.
• Display the current parameters of the serial port. See Table C–1 for a list of
the serial port parameters.
• Display the node parameters for the router. The node parameters are the rout-
er password, Ethernet down-line loading (enabled or disabled), and the router address.
C.3.3 TEST Command
Use the TEST command to perform loopback testing on the serial port and its associated cable and modem. The test command has four modes:
• Internal loop ––Use this mode to run the self-test loopback tests. The port
connector and its internal wiring are not checked during this test.
• External loop –– Use this mode to test:
C–4 DEC WANrouter 90 Owner’s Manual
Page 95
– A port connector and its internal wiring. You must terminate the port
with an H3199 loopback connector.
– The port connector, its internal wiring, and associated cables. You must
terminate the cables with a loopback connector.
• Local loop –– Use this mode to test as far as the local modem. This test as-
sumes that the modem recognizes the local loop modem signal.
• Remote loop –– Use this mode to test as far as the remote modem. This test
assumes that the remote modem recognizes the remote loop modem signal.
C.3.4 CONTINUE Command
Use the CONTINUE command to exit BCP.
C.3.5 How to Abort a Command Within BCP
To abort a CONFIGURE/SHOW/TEST command, press the Escape key.
