DECserver 900TM
INSTALLATION

LKG–8088-93I

The DECserver 900TM is a 32-port network access server that connects asyn–
chronous devices, including terminals, printers, modems, or PCs to an Ethernet
local area network (LAN). It operates in a DEChub 900 MultiSwitch or as a standalone access server. The DECserver 900TM is configured with 32 MJ8 (RJ-45) connectors, and provides limited modem control with the 8-pin connectors. Each port
supports 16 baud rates from 75 baud to 115.2 Kbaud. The DECserver 900TM includes 4 megabytes (MB) of standard memory, and can be expanded to 8 MB.

FCC NOTICE – Class A Computing Device:
This equipment generates, uses, and may emit radio frequency energy. The equipment
has been type tested and found to comply with the limits for a Class A computing device
pursuant to Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable
protection against such radio frequency interference when operated in a commercial
environment. Operation of this equipment in a residential area may cause interference; in
which case, measures taken to correct the interference are at the user’s expense.

VCCI NOTICE – Class 1 Computing Device:
This equipment is in the 1st Class category (information equipment to be used in
commercial and/or industrial areas) and conforms to the standards set by the Voluntary
Control Council for Interference by Data Processing Equipment and Electronic Office
Machines aimed at preventing radio interference in commercial and/or industrial areas.
Consequently, when used in a residential area or in an adjacent area thereto, radio
interference may be caused to radios and TV receivers.
Read the instructions for correct handling.

1) Power LED. Lights when the module has power.
2) Module OK LED. Lights when the module passes selftest. Flashes when a non-fatal error occurs on self-test.
If the module fails self-test, the Module OK LED is off.
3) Network Traffic. Flashes or remains on depending on
network activity.
4) Network OK. Lights when the module has an active network connection.

5) Seven-Segment Display. Provides error and status
information.
6) Flash RAM Slot. Provides an opening in which to insert
the Flash RAM card.
7) Reset Switch. Resets the module to factory defaults.
To reset: while turning on the power, press and hold the
reset switch until the Module OK LED flashes; or if the
DECserver 900TM is in operational mode (the seven
segment display shows the “race track” pattern), hold the
switch in for 5 seconds. The module reboots with factory
defaults.
8) Serial Port Connectors. Connect the asynchronous
devices to the DECserver 900TM. The serial port connectors are labeled 1 to 32.

Installing the Module into a DEChub 900 MultiSwitch
You do not have to shut off the DEChub 900 MultiSwitch power when you install a module in the
hub. The DECserver 900TM has a built-in hot-swap switch that allows quick and easy power-on
installation and removal.

Install the module into the DEChub 900 MultiSwitch.
a. Check the Hub Manager Status Display to ensure that there is
adequate power in the DEChub 900 MultiSwitch to accommodate
this module’s power rating. You may have to add another
power supply to the DEChub 900 MultiSwitch to accommodate
this module without affecting other modules already in the hub.
b. Locate an available DEChub slot.
c. Place the module’s bottom mounting tab into the mounting slot
on the hub.
d. Pivot the module on the mounting tab and align the connectors.
You hear the release lever click when the module is seated.
e. Press down on the release lever to ensure that it is locked.

The release lever is
lifted and clicks
back into place
as the module
is seated

f. Seating the module initiates the power up sequence and
self-test within 10 seconds if the available DEChub power is
sufficient. Read the Hub Manager Status Display for the
module status and power consumption.

DECserver 900TM

Installing the Module in a DEChub 900 MultiSwitch (continued)
 Verify power.
a. With power on in the DEChub, verify
that the Power LED is on.
b. Verify that the Module OK LED
remains on after the module
completes self-test.

LKG–8091-93I

Connect the port cables.
Connect the port cables to any
available port connector on the module.
Notes:
Port 1 by default may be used as a
console port.
The DECserver 900TM does not support the out-of-band management
(OBM) port or the setup port on the
DEChub ONE. No devices should be
connected to these ports.
Module installation is complete.

LKG–8090-93I

DECserver 900TM

Installing Flash RAM
If you using a Flash RAM card for loading the operational software, perform the following:

Insert the Flash RAM card into the Flash RAM slot on the front of the module.
a. The Digital label should be on the same side as the DECserver 900TM logo on
the front panel of the module.
b. When properly inserted, the Flash RAM card protrudes from the front panel about 1/4 inch.
The Flash RAM card is keyed and cannot be inserted improperly.

LKG–8091-93I

The Flash RAM card can be hot swapped and may be inserted or removed at anytime. If you are booting from the Flash RAM card, insert it before powering the module or during the self-test phase.
Once you boot the DECserver 900TM, the card may be left in place or removed.

DECserver 900TM

Removing the Module from the DEChub 900 MultiSwitch

Disconnect the port connector cables from the module.

Remove the module from the DEChub.
a. Lift the release lever on top of the
hub slot.
b. Pivot the module back on its bottom
mounting tab until it disengages from
the hub.

Cabling (continued)
Before connecting cables to the DECserver 900TM ports, you must verify supported modem
signals with the person managing the DECserver 900TM. This information is necessary to
determine what cables to use. For more information on the signals, refer to the Network
Access Server Management manual.

MIBs and RFCs
Obtaining RFCs and Digital Private MIBs: Using ftp
You can obtain Requests for Comments (RFCs) and up-to-date DEChub Management Information
Base (MIBs) from Digital using anonymous ftp.
Digital offers Internet anonymous ftp access to private MIB information, in ASCII text
form, at GATEKEEPER.DEC.COM, with up-to-date documents stored in the directory
/private/mib. Check the index file and the reamdme file for the current contents. To
use anonymous ftp to copy files, follow these instructions:
1. Use the Internet application ftp to connect to gatekeeper.dec.com (the Internet
address is 16.1.0.2).
2. Log in as user anonymous.
3. Use your electronic mail address as the password.
4. Use the cd command to get to the directory /private/mib
5. Use the ascii command to specify that you are retrieving ASCII text files.
6. Use the get command to get the file or files that you require.
7. When you are finished, use the quit command to log out.
Note that user input is case sensitive; you must type it as shown (user input is shown in
boldface type).
Here is an example of copying the readme file from the repository.
