Chapter 1Introduction1.1 About the MAXserver 1600 and 1608The MAXserver 1600 and 1608 are stand-alone terminal servers that provide:Serial Ports -- The MAXserver 1600 provides16 asynchronous serial communication ports with RJ-45interfaces. 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 forthe DEC Local Area Transport (LAT®) and TCP/IP protocols.Memory Card -- An optional Memory card, from which the unit can load its operating software. Twomemory 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 updatedThe MAXserver 1600 and 1608 can also load software from the Memory card, over the network, toMAXserver 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, theunit loads its operating software from a network host called a load server. The load server is typicallya UNIXTM or VAX/VMSTM system. Alternatively, a Xyplex MAXserver Manager card (MAXman) orMAXserver 1800/1820 terminal server can be used. The load server downloads a software image tothe 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 factoryinstalled memory. The memory can be expanded in 2 MB increments, up to 5 MB, using SIMM memorymodules. SIMMs should be installed by qualified personnel only. To upgrade your MAXserver 1600 or1608, contact your Xyplex sales representative. The order code for a 2 MByte SIMM memory upgrade kitis 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 provideconcurrent support for RTS/CTS flow control signals and modem control signals on all 16 ports. Newadaptors 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, ifsupport for the new signals is not required. (Refer to Section B.3.3 for more information.)Figure 2-3 shows a front view of the MAXserver 1600/1608. Figure 2-2 shows a rear view.0590 9
