For MS-DOS load host support, refer to the Configuration Chart in the 
DECnet-DOS Software Product Description, (SPD 50.15.xx), for a list of 
supported configurations.

Processor Restrictions

A TK50 Tape Drive is required for standalone MicroVAX 2000 and 
VAXstation 2000 systems. 

Every load host on which the DECrouter 2000 software is installed must 
contain:

oo     A valid system configuration for the relevant operating system and 
      for the appropriate DECnet product (Refer to the DECnet and 
      appropriate operating system SPDs). 

oo     A supported connection on the same LAN as the DECrouter 2000.

oo     A appropriate device available to read the software during 
      installation:

For VMS and MicroVMS Operating Systems:

oo     Magnetic tape or TK50 drive.

For ULTRIX-32 Operating Systems:

oo     Magnetic tape or TK50 drive.

For MS-DOS Operating Systems:

oo     RX24 or RX31 drive (a minimum of two drives, at least one of which 
      must be capable of reading 5.25 inch 360 Kbyte diskettes or 3.5 
      inch 720 Kbyte diskettes).

Block space requirements (Block Cluster Size = 1):

For VMS and MicroVMS Operating Systems Without TRACE:

Disk space required for installation:			    2,100 blocks
							   (1075K bytes)

Disk space required for use (permanent):		    7,100 blocks
							   (3635K bytes)

For VMS and MicroVMS Operating Systems With TRACE:

Disk space required for installation:			    2,500 blocks
							   (1280K bytes)

Disk space required for use (permanent)			    7,500 blocks
							   (3840K bytes)

For ULTRIX-32 Operating Systems:

Disk space required for installation:			    2,100 blocks
							   (1075K bytes)

Disk space required for use (permanent):		    7,100 blocks
							   (3635K bytes)

For MS-DOS Operating Systems:

Disk space required for installation:			    2,100 blocks
							   (1075K bytes)

Disk space required for use (permanent):		    7,100 blocks
							   (3635K bytes)

These counts refer to the disk space required on the system disk. The 
sizes are approximate; actual sizes may vary depending on the user's 
system environment, configuration, and software options. The space 
indicated for permanent occupancy includes 5000 blocks that should be 
reserved to receive one upload dump.

The DECrouter 2000 software requires the DEC MicroServer or DEC 
MicroServer-SP hardware unit, available as follows: 

oo     DEMSA-AA for use with 120 V AC power supplies

oo     DEMSA-AB for use with 240 V AC power supplies

oo     DEMSB-AA for use with 120 V AC power supplies

oo     DEMSB-AB for use with 240 V AC power supplies

The DEC MicroServer and DEC MicroServer-SP have a built-in LAN 
controller but need a suitable connection to connect to the customer's 
LAN, together with any necessary extension cables.

The DEC MicroServer and DEC MicroServer-SP use adapter cables to provide 
the necessary interchange circuits at the appropriate electrical 
interface types and ISO standard connections for each synchronous line.  
One of these cables is needed for each line that is used. The following 
table shows the cable numbers for each of the electrical interface 
types.

                             Adapter Cables

    Electrical Interface Type            Adapter Cable     Connector/pinout

    CCITT V.28/V.24 (EIA-RS232-C/D)	 BS19D-02	   ISO 2110
    CCITT V.10 (EIA-RS423/449)		 BC19E-02	   ISO 4902
    CCITT V.36/X.27(V.11, EIA-RS422/449) BC19B-02	   ISO 4902
    CCITT V.35				 BC19F-02	   ISO 2593
    CCITT X.21 {1980} (Leased services)	 BC19C-02	   ISO 4903

The BS19D-02 cable provides the V.28/V.24 (RS232-D) interface, but is 
supplied with an adapter that allows it to be used for RS232-C as well.

CLUSTER ENVIRONMENT

VMS and MicroVMS Load Host Only

This layered product is fully supported when installed on any valid and 
licensed VAXcluster* configuration without restrictions. The HARDWARE 
REQUIREMENTS sections of this product's Software Product Description and 
System Support Addendum detail any special hardware required by this 
product.

*     V5.x VAXcluster configurations are fully described in the 
      VAXcluster Software Product Description (29.78.xx) and include CI, 
      Ethernet and Mixed Interconnect configurations.

Note that the configuration procedure needs to be executed on each node 
that is requiree to be a load host.

SOFTWARE REQUIREMENTS

The DECrouter 2000 needs at least one DECnet Phase IV node to act as a 
load host.  That system needs to be a VAX-based system running the 
MicroVMS or VMS Operating System.
