Introduction
1.1 About the MAXserver 1600 and 1608
The MAXserver 1600 and 1608 are stand-alone terminal servers that provide:
Serial Ports -- The MAXserver 1600 provides16 asynchronous serial communication ports with RJ-45
interfaces. The MAXserver 1608 provides eight ports. (See Figure 2-4 for connector signal assignments.)
Ethernet Interfaces -- A 15-pin standard Ethernet Attachment Unit Interface (AUI) connector and a
"ThinWire" Ethernet interface (BNC connector). (See Figure B-1 for AUI connector signal assignments.)
TCP/IP and LAT Protocol Support -- The MAXserver 1600 and 1608 provide concurrent support for
the DEC Local Area Transport (LAT®) and TCP/IP protocols.
Memory Card -- An optional Memory card, from which the unit can load its operating software. Two
memory card types are currently available from Xyplex:
-“Flash” cards, which are readable/writeable and can be upgraded to a newer software version
-“ROM” (or "OTP") cards, which are read-only and cannot be updated
The MAXserver 1600 and 1608 can also load software from the Memory card, over the network, to
MAXserver 1100/1120, 1500/1520, 1600/1608, and 1800/1820 terminal server units.
Network Software Loading -- If you order a MAXserver 1600 or 1608 without a Memory card, the
unit loads its operating software from a network host called a load server. The load server is typically
a UNIXTM or VAX/VMSTM system. Alternatively, a Xyplex MAXserver Manager card (MAXman) or
MAXserver 1800/1820 terminal server can be used. The load server downloads a software image to
the MAXserver 1600/1608, over the network, whenever the terminal server is powered on or re-
initialized. The load server can support other devices as well.
Expandable Memory -- The MAXserver 1600 and 1608 are shipped with either 1 MB or 3 MB of factory
installed memory. The memory can be expanded in 2 MB increments, up to 5 MB, using SIMM memory
modules. SIMMs should be installed by qualified personnel only. To upgrade your MAXserver 1600 or
1608, contact your Xyplex sales representative. The order code for a 2 MByte SIMM memory upgrade kit
is MX-500-5744. (If you only need installation instructions, the order code is MX-420-0608.)
Concurrent Flow Control and Modem Control Support -- The MAXserver 1600 and 1608 provide
concurrent support for RTS/CTS flow control signals and modem control signals on all 16 ports. New
adaptors are available to support cabling to MAXserver 1600/1608 ports when these signals are used.
In most cases, the MAXserver 1600/1608 can also use existing MAXserver 1000-series cabling, if
support for the new signals is not required. (Refer to Section B.3.3 for more information.)

Introduction
1.1.1 Supported Communication Speeds
The MAXserver 1600 and 1608 support communication speeds of 110 bps to 38.4 Kbps.
1.2 Software Requirements
The MAXserver 1600 and 1608 require Xyplex TCP/IP-LAT software, Release 4.1 or greater. The units
are configured at the factory to load software from a Memory card, if one is inserted in the card slot. If a
card is not present, the unit requests software from a network load server, which can be:
•A MAXserver 1600 or 1608 that is equipped with a Memory card
•A MAXserver Manager (MAXMAN) card or MAXserver 1800/1820 terminal server
•A VAX/VMS host system, from which the unit can load via DEC Maintenance Operations
Protocol (MOP)
• A UNIX system running:
- Bootstrap protocol (BOOTP) and Trivial File Transfer Protocol (TFTP), or:
- Reverse Address Resolution Protocol (RARP) and TFTP
The load server downloads a software image to the MAXserver 1600 or 1608, over the network, whenever
the unit is powered on or re-initialized. By default, the MAXserver 1600/1608 requests software from each
type of load server, until a server responds with a software load offer. (Section 3.2 provides a detailed
description of the software loading process.)
If you need to install software on a network load server, refer to the Software Installation Guide for the type
of load server you plan to use.
1.2.1 Changing the Software Loading Method
You can change the method the MAXserver 1600 or 1608 uses to load its software. For example, you can
configure the unit to load exclusively from a specific type of load server; or, you can configure the unit to load
from the Memory card only. You use the ROM Configuration menu to change the software loading method.
(Refer to Chapter 4 for more information.) Alternatively, you can use DEFINE SERVER commands to change
the software loading method. (Refer to the TCP/IP-LAT software documentation for more information.)
1.3 Parameter Storage
The MAXserver 1600 and 1608 are configured at the factory to store configuration data (parameters)
locally, in Non-volatile storage (NVS). As an option, you can configure the unit to load parameters from a
network host, called a parameter server, using the ROM Configuration Menu. (Refer to Chapter 4 for
more information.) Alternatively, you can use DEFINE SERVER commands to change the parameter
loading method. (Refer to the TCP/IP-LAT software documentation for more information.)
