Notes:
1
Letter D = Data device only.
Letter L = Valid ULTRIX load device.
2
Although there are four ports, ports 1 and 2 are not available. Port 3 is system console. Port 4 is available for printer or
modem.
3
The modems must be configured such that the
Forced DSR
attribute is NOT set on the modem. If the
Forced DSR
attribute
is set, the modem will be unable to recognize loss of connection, and may incorrectly assume that a connection has been
established. Consult the modem’s Owner’s Manual for specific information on clearing the
Forced DSR
option.
4
The SCSI (Small Computer System Interface) cable length is limited to six meters, thereby limiting the number of external
devices (tapes and disk) that can actually be attached to the system per bus.
5
Disk and tape devices are connected to the DECsystem and DECstation via SCSI (Small Computer System Interface). There
is one integral SCSI controller and, optionally, up to three more SCSI controllers may be added. Each SCSI controller will
support up to seven devices in any combination. Each controller has an identifier which can be set via the DS5000 Console
Interface (the factory default is id6). Each added device must have its own unique identifier which must not conflict with any
other device on its bus including the SCSI controller. The SCSI controller should always have the highest id.
6
On the DECsytem 5000 Model 25/33/50, the RX26 device may either be FDI-based, in which case it is integral in the system;
or SCSI-based, in which case it is a separate device. On the DECsystem 5900, the RX26 is SCSI-based.
7
The DECsystem 5000 Model 25/33/50 has one general purpose asynchronous/synchronous serial interface on the system
module. A TURBOchannel-based serial connector would be needed if more serial lines are required.
8
DEClaser support is equivalent to that which is available for the LN03, LN03R, and LN03S printers.
9
The RZ23, RZ23L, RZ24 and RZ24L devices are supported via the TURBOchannel Extender (TcE) box.
10
Disks and tapes supported on the CITCA are those CI devices already supported on the DECsystem 5800 series platforms,
e.g. ESE20, TAxx tapes, RAxx disks and HSCxx controllers. Devices connected to CITCA are supported as data devices
only.
11
Accepts TK50 distribution media.
12
Automatic stack loader tape drives are supported only by the dump, restore and cpio system utilities.
