Getting Started with MAXserver Access Servers

About the MAXserver

The MAXservers are standalone access servers that provide:

Serial Ports – The MAXserver is available in the following configurations:

The MAXserver 1620 provides 20 asynchronous serial communication

ports with RJ-45 interfaces.

The MAXserver 1640 provides 40 asynchronous serial communication

ports with RJ-45 interfaces. (See Figure 4 for connector signal assignments.)

The MAXserver 1608 provides 8 asynchronous serial communication

ports with RJ-45 interfaces.

The MAXserver 1604 provides 4 asynchronous serial communication

ports with RJ-45 interfaces.

0038

Figure 4 and Figure 5 show rear and front views of the MAXserver 1620 and MAXserver 1640. Figure 6 and Figure 8 show rear and front views of the MAXserver 1608A and MAXserver 1604.

NOTE: The front and rear panels of the MAXserver 1608A are

identical to the MAXserver 1620 and 1640 except for the number of ports available.

Ethernet Interfaces -- A 15-pin standard Ethernet Interface Attachment Unit Interface (AUI) connector and a 10Base-T Ethernet interface (RJ-45 connector). (See Figure 15 for AUI connector signal assignments.)

TCP/IP and LAT Protocol Support -- The MAXserver provides concurrent support for the DEC Local Area Transport (LAT®) and TCP/IP protocols.

Page 14

Getting Started with MAXserver Access Servers

Flash Card -- An optional card, from which the unit can load its operating

software.

The MAXserver can also load software from the flash card to other NBaseXyplex access server units on the network for which it has a load image.

Network Software Loading -- If you order a MAXserver without a flash card, the unit loads its operating software from a network host called a load server. The load server is typically a UNIXÔ or VAX/VMSÔ system. However, you can also use a MAXserver Manager card (MAXman) or another MAXserver. The load server downloads a software image to the MAXserver over the network whenever the access server is powered on or re-initialized. The load serverm can support other devices as well.

Expandable Memory – All MAXserver units are shipped with 4 MB of factory installed memory. The memory can be expanded in 2 MB increments, up to 8 MB, using SIMM memory modules. SIMMs should be installed by qualified personnel only. To upgrade your MAXserver, contact your NBase-Xyplex sales representative or distributor. Installation instructions are provided later in this Guide.

Concurrent Flow Control and Modem Control Support -- The MAXserver provides concurrent support for RTS/CTS flow control signals and modem control; signals on all ports. Adapters are available to support cabling to MAXserver ports when these signals are used. In most cases, the MAXserver can also use standard MAXserver 1000-series cabling, if support for the new signals is not required.

Downloading Software

MAXservers are configured at the factory to load software from a flash 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 that is equipped with a flash card

A MAXserver Manager (MAXMAN) card or Network 9000 processor

module

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

0038

Page 17

Getting Started with MAXserver Access Servers

The load server downloads a software image to the MAXserver, over the network, whenever the unit is powered on or re-initialized. By default, the unit requests software from each type of load server, until a server responds with a software load offer.

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.

Configuration Options

There are two Graphical User Interface configuration utilities that you can use instead of using the Access Server Configuration Menu or the Command Line interface to configure the MAXserver. These utilities simplify the task of configuring MAXservers - FocalPoint and ControlPoint.

About FocalPoint

FocalPoint for Access Servers is a Windows-based configuration utility with a point-and-click graphical interface (GUI) designed to step you through the process of configuring MAXservers.

0038

FocalPoint guides you through the logical progression of setup choices complete with default settings and context-sensitive online help.Using FocalPoint to configure the MAXserver eliminates the need to learn a complex command line interface.

FocalPoint automatically ships free of charge on the software and documentation CD with all Network 3000, Route Runners, MAXserver, and 720 Series Access Server modules for the Network 9000. The latest versions of FocalPoint software are also available from the NBase-Xyplex Web Site.

Page 18

Getting Started with MAXserver Access Servers

To use FocalPoint, simply load the software from the CD that was shipped with the MAXserver. From FocalPoint, you can select your MAXserver model and also provide all pertinent information before you can advance to the next step. FocalPoint will not prompt you for options not available to your system.

Figure 2 - Sample FocalPoint Configuration

About ControlPoint

Installation

This section explains how to install a MAXserver and place it into operation. The basic installation consists of the following procedures:

1. Unpack the unit, check the contents against the packing list, and inspect for possible damage during shipping.

2. Mount the unit in a standard 19" rack or place it on a suitable flat surface (19" x 15").

3. If the unit is equipped with a flash card, insert the into the card slot on the front of the unit.

NOTE: NBase-Xyplex recommends that you wear a

grounded wrist strap when you insert the card. If none is available, ground yourself by placing one hand on the unit (or another grounded object), before you insert the flash card, to prevent static from being discharged into the unit.

4. If the unit is not equipped with a flash card, verify that Release 5.3 or greater of Access Server software is installed in the network (Release

6.0.3 or higher if using the MAXserver 1604 or 1608B).

5. If you are installing a unit that is equipped with a flash card, as well as units that are not, install the unit with the flash card first. That unit can then serve as a load server for th e other units.

6. Connect the Ethernet transceiver cable or 10Base-T network cable to the unit.

0038

Page 21

Getting Started with MAXserver Access Servers

7. Connect the power cord to rear of the unit, then to an AC power outlet, and observe the front panel lights.

8. Connect the serial device cables to the unit and to the devices (terminals, PCs, etc.), and initialize the devices.

The following sections provide more detailed installation instructions.

Unpack and Inspect the Unit

Follow these steps:

1. Carefully unpack the unit shipping carton.

2. Inspect the contents and make sure that you received all parts listed on the shipping order.

3. Place all packing materials back into the shipping carton and save the carton. (If you need to return the unit to NBase-Xyplex or your distributor, you should return it in the original carton.)

0038

4. If the unit has been damaged in shipping or any parts are missing, notify your NBase-Xyplex representative or distributor immediately.

Place the Unit on a Flat Surface or Mount on Rack

Select a location for the unit that meets the following requirements:

Adequate Space -- A standard 19" rack or a 19" x 15" flat, stable surface such as a shelf or desktop must be available or use the instructions in Section 2.3.1 to mount it in a standard 19" rack.

You can locate the unit in a variety of environments, including an office or computer room, provided the environmental requirements are met.

Page 22

Getting Started with MAXserver Access Servers

To reduce the possibility of dust entering the unit and to allow easy inspection of the unit's front panel lights, make sure that the MAXserver is located at an optimum distance (preferably not less than 18 inches/45 centimeters) from the floor.

Environment -- Do not choose a location where the unit will be exposed to direct sunlight or subjected to vibration. Also, the unit must be installed in an environment with 20% to 80% humidity, noncondensing, 0° - 40° C (32°113° F).

Do not remove the MAXserver unit's "feet."

Do not place an object on the side(s) of the unit that might block airflow through the unit.

Rack Mount Installation (opt ional)

Rack mount installation is easier when performed by two persons -- one person holding the unit while another secures the mounting bolts with a Phillips-head screwdriver. (Threaded clips and bolts are supplied with the unit).

Complete these steps:

1. Locate a mounting position on the rack that allows at least one inch of space above and below the unit.

2. Secure the unit to the mounting rack using the supplied bolts, as shown in Figure 3. If the rack is not threaded, use the threaded clips supplied with the server.

10Base-T Connection -- Install the Ethernet cable by plugging it into the 10Base-T connector on the rear of the unit. (The 10Base-T connector signal assignments are shown in Figure 26.) If you use the 10Base-T connector, the LINK LED will light when the unit detects that it is connected to a working Ethernet network.

Page 26

Getting Started with MAXserver Access Servers

Connect the Power Cable

You do not need to set the unit for 115V or 230V operation. The power supply automatically adapts to the input voltage.

A grounded AC power outlet should be located within six feet of the back of the unit. You can use a UL-approved, 3-prong extension cord if necessary, provided it has sufficient current and voltage capacity. (The cord must have sufficient capacity for the input power, and AC power must meet the criteria listed in).

To connect the power cable, complete these steps:

1. Plug the AC line cord (supplied) into the AC power receptacle on the rear of the unit. (See Figure 4 for the l ocation of the power receptacle.)

2. Plug the other end of the cord into a grounded 3-prong AC power outlet (or a UL-approved extension cord with sufficient capacity that is plugged into a suitable outlet).

3. When you apply power, the unit performs a self test of its circuitry and then proceeds to load its software. When the unit has finished loading its software, the RUN light flashes slowly and the LAN light flashes as Ethernet packets are received. (Figure 6 shows the locations of the lights on the front panel.)

Port Status LEDs

The port status LEDs are used in several ways. During the initialization process, the LEDs indicate that self-tests are being performed, and if any self-test fails, they indicate an error code. After the unit has received a load image and parameters, the lights indicate when a port is actively being used. In this case, each light can indicate activity for more than one port. For example, if LED 1 is lit, this can indicate that there is activity on ports 1, 11, 21, or 31. LED 2 indicates activity on ports 2, 12, 22, etc.

Connect Serial Device Cables

Connect the serial device cables to the 8-pin RJ-45 jacks on the rear of the unit. The signal assignments of the 8-pin jacks are shown in Figure 8.

Page 30

Getting Started with MAXserver Access Servers

NBase-Xyplex recommends that you label all cables with the name of the device to which it connects and the number of the port you have assigned to it. This way, if the cable is removed for any reason, you can reconnect it easily. If the device cables have not yet been prepared with the correct RJ-45 connectors, see the Cabling Considerations later in this guide.

Additional Considerations for an Internet Environment

If you plan to use the unit in an Internet environment, you must define addressing and identification characteristics to enable Internet hosts to recognize the unit as a member of the network. See the IP Addresses section later in this guide for information about configuring the unit for an Internet environment.

Factory Defaults Settings

Each MAXserver unit is confi gured at the factory to use a default set of initialization parameters that sets all ports to operate with asynchronous ASCII terminal devices in order to obtain a software image. For most configurations, the default settings can load without any configuration changes. If you are not connecting keyboard terminals or PCs running VT100 terminal emulation software, proceed to “Logging in to the MAXserver.”

The unit is also configured at the factory to store parameters locally in Nonvolatile storage (NVS) or on a flash card, if one is installed, and remotely at any properly configured parameter server. The following table lists the factory default settings.

NOTE: The default settings listed in this table are for Initialization Record

1 only. Initialization Records 2 and 3 are not enabled at the factory. However, if you enable Records 2 and 3, their default settings are the same as Record 1.

Autobauding Feature

MAXserver serial ports are configured to adjust automatically to the communication speed of a connected terminal.

Page 32

Getting Started with MAXserver Access Servers

NOTE: Access servers do not autobaud when the port receives 7-bit

characters with EVEN parity from the device until software loading has completed. You must use 8-bit characters with parity set to NONE in order to receive load messages and to enter into the ROM Configuration Menu.

You can only enable AUTOBAUD at a port set to local access and when the attached device is configured with the following settings:

CHARACTER SIZE 8, (7 if EVEN parity) PARITY NONE (EVEN if character size is set to 7) SPEED

Valid speeds between 50 and 38400. The supported port speeds are: 50, 75, 110, 134, 150, 300, 600, 1200, 1800, 2000, 2400, 4800, 9600, 14400, 19200, 21600, 26400, 28800, 33600, and 38400 bits per second (baud). The device connected to the port must be set to one of these speeds. (Ports cannot au tobaud at port speeds above 38400 bps.

To autobaud the serial port, when your terminal is powered on, keep pressing RETURN until the unit recognizes the terminal. When you do this, the serial port adjusts to the communication speed of the terminal. (This process is called autobauding.)

0038

Page 33

Getting Started with MAXserver Access Servers

Reinitializing/Powering Off the Unit

The MAXserver always stores permanent parameters (i.e., those parameters that you change using the DEFINE or PURGE command) in local storage.

Some of the DEFINE SERVER Commands require that you reboot the server for the changes to take effect. A complete listing of these server commands are located in the Define Server section of Commands Reference Guide. Always reboot the server using the INITIALIZE DELAY command to prevent corruption of the parameter storage. Commands that require reinitialization display the following message when you press the RETURN key:

XYPLEX - 705 - CHANGE LEAVES APPROXIMATELY XXXXXXX BYTES FREE

These commands cannot be modified by a SET command, because the server must redistribute memory resources for the feature during the boot-up process.

0038

Before you reinitialize, cycle power, or power off the unit, make sure that the parameter storage process has completed or the permanent parameters may be corrupted.

To reinitialize the unit, use the privileged command:

XYPLEX>> INITIALIZE DELAY 0

Issuing this command ensures that parameters have been stored before the unit reinitializes.

Resetting the MAXserver

Before you power off the unit, use the following command to ensure that the unit has completed storing parameters:

MONITOR PARAMETER SERVER

Figure 9 - Monitor Parameter Server Display

The storage process is completed when the “Status” column on this display says “Current” for all parameter servers, and the “Storage State” field says “Idle.” When these conditions are met, you can turn the unit off.You can reset the MAXserver to force it to run a self test or to re-initialize the unit. Before resetting the server, check the port lights to make sure that no connections are in progress. All connections are terminated when the server is reset.

To reset the MAXserver, follow these steps:

1. Make a simple "tool" from an ordinary paper clip by bending one end outward. You need this tool to press the RESET button located behind the MAXserver front panel.

2. Look for the small hole between the CONSOLE light and the light labeled '1’ (see Figure 10).

3. Use the paper clip tool to press the RESET button once. This halts all MAXserver operations -- the server will no longer send or receive network data or data from its connected devices. When the MAXserver enters RESET state, all front panel lights illuminate.

4. Press the RESET button again. The MAXserver begins its self test.

If the MAXserver detects an error, the front panel lights illuminate

as described in the Troubleshooting section of this guide. This error sequence continually repeats until the error is corrected or you power off the MAXserver. During this time, no data is exchanged over the Ethernet cable or server ports.

If the MAXserver does not detect an error, it will begin loading

software from the flash card or begin requesting a network load (if no flash card is present). Once loaded, the MAXserver resumes normal operations.

0038

If your MAXserver does not behave in t h is manner, see the Troubleshooting section for advice.

Logging in to the Access Server

When your terminal is properly connected to the unit, turn its power ON, then press <RETURN> (or ENTER) a few times -- until the unit recognizes the terminal. When the unit responds, you see the following message on your screen:

WELCOME TO THE XYPLEX ACCESS SERVER.

ENTER USERNAME>

Type your name, your initials, or a nickname, then press <RETURN>.

You can type up to 16 characters (numbers or letters). This name is your identifier during this session. If you choose, you can change this information each time you make a connection. It will be shown whenever you or any other person on the network requests information about who is connected to the unit.

0038

After you enter your username, the unit returns the local command prompt:

XYPLEX>

To allow the system administrator to modify server and port settings, you must be in privileged mode. To enter privileged mode, use the following command:

XYPLEX> SET PRIVILEGED

The password prompt displays. Enter the default password “SYSTEM” . The password is not case-sensitive.

Telneting i nto the Access Server Console Port

Do the following to telnet into the console port on an access server:

NOTE: You should issue both the DEFINE and SET commands

where they are indicated in the foll owing procedure. Issuing both the DEFINE and SET commands ensures that the parameter change will take effect without rebooting the unit.

1. Configure the essential IP characteristics on the Access Server as follows:

a. Configure the IP Address to be assigned to the access server:

define server ip address [ set server ip address [

ip-address

]

b. Disable the Subnet Mask Autoconfigure feature. This disables the

access server’s ability to automatically define the natural subnet mask based on the IP address assigned to the unit. For example, the default subnet mask for a Class B network is 255.255.00. The default setting for Subnet Ma sk Auto-configure is ENABLED. You must disable the autoconfigure feature in order for the server to save any other variable-length subnet mask.

Use the following commands to disable the Subnet Mask Autoconfigure feature:

define server ip subnet mask autoconfigure disabled set server ip subnet mask autoconfigure disabled

0038

Page 40

Getting Started with MAXserver Access Servers

c. Configure the Subnet Mask for the access server. The subnet mask

must be consistent with the network on which the access server will reside. Use the following commands:

define server ip subnet mask [ set server ip subnet mask [

ip-address

]

d. Configure the default first-hop Router/Gateway:

define server ip primary gateway address [ set server ip primary gateway address [

ip-address

]

2. Specify Telnet Port 2000 when connecting remotely: Be sure to specify telnet remote port# 2000 when trying to connect. If no

port/socket number is specified, then most Telnet applications will use port 23 by default. Unless the Xyplex's console port has also been redefined to port 23, then any attempts to Telnet into the server's console port will be refused.

The current port setting on the access server is displayed in the “Remote Port” field of the “show port 0 telnet characteristics” screen. Figure 11 shows a “show port 0 telnet characteristics” screen with the “Remote Port” field set at 2000.

Page 41

Getting Started with MAXserver Access Servers

If you are trying to telnet from one NBase-Xyplex device into another

NBase-Xyplex access server’s console port, the command you will use is:

telnet x.x.x.x:2000

where “x.x.x.x” represents the IP address of the destination access server. For example, enter

telnet 140.179.41.59:2000

to reach the

console port of the server having an IP address of 140.179.41.59.

NOTE: Port# 2000 must be specified when trying to remotely connect

to the access server. If no port/socket number is specified, then most Telnet applications will use port 23 by default. Unless the access server’s console port has also been redefined to port 23, any attempts to Telnet into the server's console port will be refused.

3. When you are connected to the access server, press the Enter key one more time to display the login password prompt (#).

0038

4. Type the default login password “access” at the # prompt, and press the Enter key.

NOTE: The password is not echoed as you type.

5. If you entered the password correctly, the

Enter username>

prompt

will be displayed.

6. Enter any name at the

Enter username>

prompt, just as if you were

connected locally to one of the serial ports.

The

Xyplex>

prompt is now displayed.

Getting Started with MAXserver Access Servers

Changing the Telnet Remote Port

While you are logged into a port in privileged mode, you can change the telnet remote port on port 0 from 2000 to 23. Use the following commands:

define port 0 telnet remote 23 logout port 0

Now you can telnet to the IP without a socket number.

Passwords

The following passwords are the defaults the first time you use the MAXserver.

To log on to the server at the # prompt, the default login password is

ACCESS.

To set privileged mode at the Xyplex> prompt, the default privilege

password is SYSTEM.

These passwords prevent persons who do not know them from accessing the server. Change the default passwords to other values as part of your basic server setup.

IMPORTANT

If you change the default password, make sure that the new

password is written down in a safe location. If you forget the password, the server will need to be reset to factory default settings.

0038

Page 43

Getting Started with MAXserver Access Servers

When you enable the Login Password feature on a server port, a person attempting to log on to that port must enter a password in order to gain access. A single password is used at all ports where the feature is enabled. The login password feature is optional. The server does not prompt for it unless you enable it on a port.

Use the following command to enable the Login Password feature. The feature is disabled by default.

DEFINE PORT [

port-list

] PASSWORD ENABLED

Then define a password. The default login password is ACCESS. The password can be between 1 and 16 characters. Enclose the password string in quotes.

DEFINE/SET SERVER LOGIN PASSWORD "password"

Examples

Xyplex>> DEFINE PORT 1-8 PASSWORD ENABLED

Xyplex>> DEFINE SERVER LOGIN PASSWORD "login123"

Privilege Password

You must enter the privilege password to set a port to privileged mode. The default password is SYSTEM. You can specify the privilege status of a port where commands are issued. More th an one port on an access server can be privileged. Any user who knows the privileged password can use the SET PRIVILEGED command.

0038

Page 44

Getting Started with MAXserver Access Servers

NBase-Xyplex recommends that you change the default password to restrict

access to the commands that:

Change the server’s settings

Affect other users’ ports

Affect access to destinations on the network

You might want to change the privilege password periodically, to limit the

number of users who can set privileged mode.

Use the following command to define the privilege password:

DEFINE SERVER PRIVILEGE PASSWORD "password"

The password you define with this command is what users must type in order to use privileged server commands. The password can be between 1 and 16 characters. Enclose the password string in quotes. The default password is SYSTEM. There can be only one privileged password per server.

If you do not type the password on the command line, the system will prompt you for a password. In this case, do not enclose the password in quotation mark characters.

Example

Xyplex>> DEFINE SERVER PRIVILEGE PASSWORD "manager"

0038

Page 45

Getting Started with MAXserver Access Servers

Lost Passwords

NBase-Xyplex access servers are extremely secure. If you should lose your password, reset the unit back to factory defaults and reconfigure as new. New passwords should be properly maintained by the system administrator.

Time-Sensitive Passwords

With the time-sensitive password scheme, the user carries a security device the size of a credit card. The device displays a periodically changing number in an LCD display. When the user dials in and gives his or her user name, the access server prompts for a password. The user enters the number currently showing on the security card. To check the password, the access server queries a local security server that is running the same algorithm as the security card. If the passwords match, the user may then use the network.

NBase-Xyplex remote access products support both dialback security and time-sensitive passwords. Time-sensitive password protection is provided using Security Dynamics' SecurID system.

0038

See the Security Features section of the Advanced Congifuration Guide for detailed information about changing the security default passwords.

Page 46

Getting Started with MAXserver Access Servers

Prompts

The local command mode prompt changes to indicate that the port is a privileged port (unless the command is issued from a console port). For example, the default local command mode prompt for a non-privileged port is Xyplex>. The default local command mode prompt for a privileged port is Xyplex>>.

The Login Password prompt appears when a user attempts to log on to a port where the Login Password feature is enabled. The default prompt is #

Use the following command to change the prompt:

DEFINE/SET SERVER LOGIN PROMPT “

Example

DEFINE SERVER LOGIN PROMPT “Login:”

Configurable Username and Password Prompts

You can define user name and password prompts for any port. To do this, use the following command syntax:

DEFINE PORT [ DEFINE PORT [

The default username/password prompt length is 26 characters. Enlcose the prompt text in quotes.

Privileges

Privilege levels determine which commands users can enter at server ports. The server supports three privilege levels, described in Table 2. The default privilege level for all ports is Nonprivileged.

Table 2 - Privilege Levels

Privilege Level

Privilege A user in privileged mode can issue all commands,

including those that change and monitor server and port settings, and th ose that reboot and shut down the server. (Many of the commands in this manual are only accepted in privileged mode.) To set privileged mode, you must enter the privilege password.

Nonprivilege A user in nonprivileged mode cannot issue commands that

change and monitor the settings of the server or other ports, or commands that reboot and shut down the server.

Security Secure ports accept certain nonprivileged commands,

including commands that establish sessions on the network and display and change port settings.

Privileged Ports

A user at a nonprivileged port can set the port to privileged mode through this command:

Xyplex> SET PRIVILEGE

Description

Type the privileged password (password is not echoed by the terminal). The default password is "ACCESS". The access server will then display the privileged local command prompt.

Xyplex>>

0038

Page 49

Getting Started with MAXserver Access Servers

The port will have privileged status. This means that the user at the port

can set or change operational and permanent parameters for the server, and any or all ports, sessions, or services. When the port is logged out, it will automatically return to a non-privileged status for the next user.

Nonprivileged Ports

To restore nonprivileged mode, issue this command:

Xyplex>> SET NOPRIVILEGE

The port will return to non-privileged status. This means that the user will only be able to change parameters for the current port or session. This is the default privilege level when connecting to a port.

Secure Ports

The Secure Privilege level might be appropriate for many ports. If you want to limit the use of a port to commands that users need for normal daily work, consider making the port secure by default. The Commands Reference Guide describes commands that are available at secure ports only. Secure ports accept commands that:

0038

Establish sessions

Display information about the port and network destinations

Change some port settings

You can change the following port settings while in Secure mode:

Session switching characters

Multisessions feature

TN3270 feature

Page 50

Getting Started with MAXserver Access Servers

Secure ports do not accept commands that affect:

Server settings

Other user's ports

The accessibility of network destinations

Use the following command to change the privilege level to Secure. Unless

you set the default privilege level of a port to Secure through the following command, a port has the Nonprivileged security level:

Flash Cards

This section describes how to use flash cards. Flash cards are readable/writeable and can be updated to a newer software version. See the Software Installation Guide for Xyplex Loaders for instructions. The commands used to update flash cards are located in the Commands Reference Guide.

You can perform the following tasks with the image file contained on the flash card:

Copy the file to another card

Delete the files

Display the current status

Format the card

0038

Load the image file

Terminate file updates

Loading the Image File

The DEFINE SERVER LOAD SOFTWARE command specifies the CARD/XMOP/MOP filename that contains the software load image. You specify this filename if CARD, XMOP, or MOP is enabled as a load protocol for the software load image, and the load image name is different from the default. The default software load image name for a MAXserver is XPCSRV20. The CARD/XMOP/MOP load image filename appears in the Server Loaddump Characteristics display shown in Figure 27.

Page 52

Getting Started with MAXserver Access Servers

Use the following command to load the image file:

DEFINE SERVER LOAD [PRIMARY] SOFTWARE “FILENAME”

[SECONDARY] [TERTIARY]

Example

This example specifies XPCSRV20 as the filename for the secondary

initialization record.

XYPLEX>> DEFINE SERVER LOAD SECONDARY SOFTWARE XPCSRV20

Changing the Software Im age Filename

The software load image filename appears in the Software field on the Loaddump characteristics display (see Figure 33). The default filename for all MAXservers is

XPCSRV20

. The filenames apply to primary, secondary,

and tertiary initialization records.

Use the following command to specify a name for the software load image file:

DEFINE SERVER LOAD [

Rebooting

Use the INITIALIZE SERVER command to reboot the access server, or to cancel a previous INITIALIZE SERVER command. Using the INITIALIZE command, the access server returns to a state which is exactly the same as if you powered up the server (i.e., all settings are restored to the values specified in the permanent database. Values specified using SET commands are reset to the values in the permanent database, users are logged out, and the server image is reloaded).

INITIALIZE DELAY Command

You can specify a delay period before the access server reboots. When you issue the INITIALIZE command without specifying a delay period, the access server broadcasts a warning to all ports notifying any users who are logged on (the default is 1 minute). If you specify a delay time which is between 2 and 29 minutes, the server will broadcast a warning immediately, and then every minute for each of the last 5 minutes, until re-initialization. If you specify a delay of 30 minutes or greater, the access server will broadcast a message immediately, once every 30 minutes prior to reinitialization, and then once every minute for the last 5 minutes. These messages are broadcast regardless of the BROADCAST setting. Broadcast messages are only displayed at ports that have BROADCAST enabled.

Getting Started with MAXserver Access Servers

If you specify INITIALIZE DELAY 0,the server will reboot immediately

unless there are unsaved parameters, in which case you will receive the "Warning Configuration Not Saved" error message (message 198). If you specify INITIALIZE DELAY n with a delay value other than 0, and a user changes a permanent parameter (i.e., uses a Define command) before n minutes expire, the initialization is delayed until the parameters are saved. If the parameter server cannot save t h e parameters, the user who entered the Define command will receive the 198 error message, and the server will not reboot.

Use the following command to reboot the server:

Cabling Considerations

NBase-Xyplex offers a family of products that support access serving features. Each product can be connected to a variety of modems or other devices through one of three wiring schemes (with 6, 7, or 8 wires) which support different modem control and hardware flow control options. A fourth wiring scheme, which is available on some products, uses 3 wires and is not suitable for modem-based applications.

Standard cabling items available from NBase-Xyplex allow you to connect to any serial device that uses a male or female DB-25 connector. All you need is the appropriate modular cable (crossover cable for connecting to a DTE device, straight-through cable for connecting to a DCE device), and the correct modular adapter (male or female DB-25 connector), which is essentially an RJ-45-to-DB25 adapter.

Ordering Cables

NBase-Xyplex also supplies DEConnect-compatible crossover cables and modular adapters for use with all MAXserver units. To order cables, adapters or other cabling accessories from NBase-Xyplex, contact your Sales representative or distributor.

Cabling Types

See the Modems section of t he Basic Configuration Guide for information about modem control and setting up modems.

Modem Control/Hardware Flow Control

MAXserver serial ports can be set up to support RTS/CTS flow control. The

Basic Configuration Guide describes flow control options and explains how to set up flow control at a port. The adapters shown in Figure 13 and 13 support RTS/CTS flow control. MAXserver serial ports can also be set up to support modem control. The Basic Configuration Guide describes modem control options and explains how to set up modem control at a port. The adapter shown supports modem control, by supporting the RING signal.

0038

Page 62

Getting Started with MAXserver Access Servers

To use modem control or hardware flow control, you need an input control

signal and an output control signal for each. This is important to consider when you decide which NBase-Xyplex unit to use for a pa rticular application, since different NBase-Xyplex units support different wiring schemes, and some units might not have enough signals for the desired application.

NBase-Xyplex cabling and software can be configured to use various combinations of modem control, and hardware flow control. There are two types of hardware flow control: DCD/DSR and RTS/CTS. DCD/DSR flow control (referred to here as "standard" hardware flow control) is the type that one would typically use with lower speed modems. RTS/CTS is used with high speed modems (typically, these modems support CCITT V.42 operation). Only one type of hardware flow control can be used at a given port. Modem control and DCD/DSR hardware flow control are mutually exclusive (i.e., only one of these can be enabled at a given port). On 8-wire interfaces, modem control can be used concurrently with RTS/CTS hardware flow control.

NOTE: You would use a "null-modem" cable when making a direct

connection between the serial ports of two access servers (i.e., no modems involved) or other DTE device. For that application, use a DTE-to-DTE cable, as described in the hardware documentation supplied with your unit.

Making Your Own RJ-45 Cabl es

If you make your own cables, you should be very careful when using the crimping tool. Make sure that the RJ-45 connector is fully inserted into the die-set cavity of the crimping tool, and that the wire is fully inserted into the RJ-45 connector, before crimping. The die set might be fragile, and could break if the RJ-45 connector is not properly seated before you squeeze the handle.

0038

Page 63

Getting Started with MAXserver Access Servers

Also, NBase-Xyplex recommends that you use different colored wires for

straight-through and crossover cables, in order to keep track of the cable type. For example, NBase-Xyplex recommends silver wire for making crossover cables and black wire for making straight-through cables.

RJ-45 Wiring Considerations

You should give special consideration to the wiring scheme when connecting a device such as a terminal to a MAXserver serial port. The MAXserver is considered a DTE device. If you want to connect to another DTE device such as a terminal that is also DTE, you will need a crossover wiring scheme somewhere in the cabling. (Communication between DTE-to-DTE devices requires a crossover.) When a DCE device is connected to a MAXserver serial port, straight-through wiring is required.

To make a modular cable with a crossover, you need only crimp the RJ-45 connector in the same direction at both ends. This crosses all wires in the cable. To make a modular straight-through cable, you need only crimp the RJ-45 connector in opposite directions at both ends. Figure 12 shows the crossover and straight-through wiring schemes.

0038

The crossover connects the MAXserver transmit data (XMT) line to the receive data (RCV) line of the user DTE device. Similarly, the MAXserver receive data (RCV) line crosses over to the transmit data (XMT) line of the user DTE device. The other signals are crossed over in a similar manner (see Figure 12).

You can obtain adapters with male and female DB-25 connectors from NBase-Xyplex. These adapters direct signals from the RJ-45 connector on the cable to the correct pin on the DB-25 connector. Figure 13 and Figure 14 show how devices are cabled when you use these adapters.

Using Existing MAXserver 1000-series Cabling

The adapters shown in Figure 13 and are designed for use with all MAXserver units. If you have existing MAXserver 1000-series cabling at your site, the cabling can be used to connect MAXserver ports to DTE devices -- provided you do not need to turn on RTS/CTS flow control at the ports. If you plan to connect the unit to a DCE device, you should use one of the adapters shown in Figure 14.

NOTES: In order to expand the functionality of the serial interface,

the MAXserver modular cabling allows you to connect different signals to pin 7 of the MAXserver. (This pin is an input to the MAXserver.) When a DCE device is connected to a MAXserver serial port, the device's DCD output is connected to pin 7. In this case, the signal at pin 7 is referred to as DCD.

When a DTE device is connected to a MAXserver serial port, the device's DTR output is connect ed to pin 7 of the MAXserver. In this case, the signal at pin 7 is referred to as DSR. (This cabling scheme also provides DECconnect compatibility, since DECconnect does not support the DCD signal.)

DEConnect RJ-45 Cables

DEConnect cables no longer available.

0038

Figure 15 shows the DEConnect-compatible cables available from NBaseXyplex and shows how the cables are wired. The Male RJ-45 connector is attached to the server. The MMJ connector attaches to the DEConnectcompatible device (DTE). The cable is a crossover cable that uses the six inner pins of the server port and makes the signals available at the MMJ connector. The cable is constructed using standard six-wire cable.

Octopus Cables

An octopus cable fans out a single 50-pin male or female Telco connector, or a 36-pin male or female Telco DEConnect connector, to eight male RJ-45 connectors. These cables enable you to connect a MAXserver's serial ports to existing wiring in your facility. For example, you can use octopus cables to connect the MAXserver's serial ports to a punch down block.

connectors

By using two types of octopus cable, you can connect MAXserver serial ports to a distribution panel that has DB-25 connectors. This enables you to adapt modular cabling to NBase-Xyplex TSERV-style cabling. NBase-Xyplex offers octopus cables that fan out a 50-pin Telco connector to 8 male or female DB25 connectors. These cables are available from NBase-Xyplex in 3', 10', and 50' lengths. You can connect the unit to the distribution panel via the two octopus cables as shown in Figure 19. (You might need an extension cable to connect the two cables.)

NBase-Xyplex 6-Wire Cabling

This cabling scheme provides XMT, RCV, DCD, DTR, RING, and ground wires. Using this cabling scheme you can use either modem control or hardware (DCD/DTR) flow control, but not both, since there are only three control signals. This scheme is useful for applications which have simple modem signalling requirements, such as:

Terminal emulation and file transfer applications (Kermit, Xmodem,

Microphone, etc).

Applications such as SLIP and PPP using low speed modems.

Figure 20 depicts the wiring that you would use to connect the serial port of

a NBase-Xyplex unit to a modem or other DCE device. For simplicity, modular cables are shown in the figure; but there are other wiring options available with this cabling scheme. (These are covered in more detail in the hardware documentation supplied with your unit.) You can purchase modular cables and adapters shown in the figure from NBase-Xyplex, or make your own cables based on the wiring diagram.

Using the Configuration Menu

This section explains each parameter in an intialization record and how to change the configuration parameters for the access server using the Configuration Menu, or you can enter the appropriate command at the Xyplex prompt instead of using the menus. Most of the time, the default values in initialization records load software automatically, so often you do not have to change them.

Each access server provides Initialization Configuration software that you use to:

View current settings of initialization parameters and change the

settings when necessary.

Change the protocol used to load parameters.

Change the protocol used to receive a software load image, or change the

name of the load image that it requests.

Change the protocol used to trans m it dump files.

Instruct the operating software, once loaded, to initialize server and port

parameters.

Configure multiple initialization (load/dump) configurations.

Change the unit’s memory settings whenever you add or remove memory

(SIMMs).

Reset the parameter initialization records to default factory settings.

Rename the software image load file.

0038

Page 81

Getting Started with MAXserver Access Servers

Loading Software Image and Parameters

When you initialize an access server, it obtains the software load image and parameter file using the information in an initialization record. The NVS for the access server maintains three initialization records. The access server first attempts to load software using the information in the primary initialization record, if it is enabled. If it cannot load successfully, it attempts to load using the information in the secondary initialization record, if it is enabled. Finally, if it cannot load successfully using the secondary initialization record, it attempts to use the information in the tertiary initialization recordif it is enabled. If all three attempts fail, the access server begins this sequence again with the primary initialization record.

You can load the initialization parameters from any of the following locations:

From a flash card installed in the unit’s flash card slot that contains the

appropriate load image.

From a host system that has the access server software installed, if a

card is not present or the appropriate image is not on the card.

0038

A MAXserver unit or a Network 9000 module that has a flash card with

the appropriate load image.

Displaying Load Status Messages

You might want to disable this feature during the software loading process if a device such as a bar code reader, which cannot interpret status messages, is connected to a serial port.

Use the LIST SERVER LOADDUMP CHARACTERISTICS command to display the current status of the status message.

Use the following command to enable or disable the loading of status messages.

Page 82

Getting Started with MAXserver Access Servers

DEFINE SERVER LOAD STATUS MESSAGE [ENABLED]

[DISABLED]

Where

Means

ENABLED Status messages display during the loading process. This

is the default.

DISABLED Status messages will not display during the loading

process.

Example

DEFINE SERVER LOAD STATUS MESSAGE DISABLED

Loading Protocols

The default protocols are tr ied in the following order: Flash Card,, Directed TFTP, XMOP, BOOTP/TFTP, MOP, and RARP/TFTP. The protocols are:

Flash Card - For MAXservers, use FlashCard (card) to load image only.

Use XMOP for loading from a NBase-Xyplex load server.

Use MOP for loading from a VAX/VMS host.

Use BOOTP, RARP, and DTFTP (Directed Trivial File Transfer Protocol)

for loading from a UNIX host. Typically, you only need to use DTFTP when loading across a router or when the load host does not support BOOTP or RARP.

You can change the default value for many prompts. The first ti me you run the Configuration Menu, the default value shown is the factory default value. After you exit from the Configuration Menu, having saved changes,

0038

Page 83

Getting Started with MAXserver Access Servers

the default value shown for a prompt is the currently stored value, not the factory default value.

NOTE: NBase-Xyplex Access Servers cannot load from a

DEC Info Server or any other device that does not support loading via DEC MOP V3 using all 5 parameters (Including the fifth parameter, which is the Host date/time stamp) for "Parameter Load with Transfer Address" using MOP.

Accessing the Configuration Menu

To access the Configuration menu, follow these steps:

1. Using a straightened paper clip, press the RESET switch once to enter reset mode. (Figure 4 shows the location of the switch.) All lights on the front panel should illuminate.

2. Press the RESET switch again, and hold the switch in. With the switch held in, observe the port lights. The port lights should first go off then light in sequence from left to right. Then all lights will go off in sequence from left to right. Then port lights 9 and 10 will go on (for MAXserver 1620/1640; ports lights 7 and 8 for the MAXserver 1608A, 1608B, and 1604). When this sequence has completed, you can release the RESET switch. Next, the unit performs the standard self-test diagnostics, as shown by lights 8 through 1 being turned on in sequence. (The self test requires about 20 seconds to complete.)

0038

3. When the RUN light flashes rapidly (indicating that the self test has completed), autobaud any serial port by pressing RETURN a few times at a terminal connected to the port. Once the serial port has selected a port speed, it generates a message that is similar to the following:

CONFIGURATION IN PROGRESS. PLEASE WAIT.

4. Type the password "ACCESS" (note that there is no prompt) and press

Page 84

RETURN. The unit displays the menu shown in Figure 28.

Displaying Initialization Records

When you initialize a MAXserver Series access server, it obtains the software load imageand parameter file using the information in an initialization record. The for the access server maintains three initialization records. The access server first attempts to load software using the information in the primary initialization recordif it is enabled. If it cannot load successfully, it attempts to load using the information in the secondary initialization record, if it is enabled. If this fails, it attempts to use the information in the tertiary initialization recordif it is enabled. If all three attempts fail, the access server begins this sequence again with the primary initialization record.

0038

You can create up to three unique "initialization configurations" (also called initialization records), numbered 1 (primary), 2 (secondary), and 3 (tertiary). (In this case, initialization refers to loading both image and parameters.)

If for any reason there are no service offers for loading and/or dumping made as a result of the first (primary) initialization configuration, the unit will try the secondary initialization configuration. If there are no service offers from that configuration, the unit will try the third (tertiary) initialization

configuration. If there are still no service offers, the unit will wait and then try again, beginning with the primary configuration. Only the primary default initialization configuration is enabled at the factory.

To display the settings for an initialization record, complete the following steps:

Type 1, 2, or 3 at the Display Unit Configuration Menu. The menu displays a list of currently stored configuration values and the new configuration values for the specified initialization configuration as shown in Figure 30.

Loading and Dumping Protocols

Each initialization record has several loading and dumping protocols enabled by default if the access server attempts to obtain software and parameters from the network.The enabled protocols determine where the access server obtains the files. Table 4 lists the enabled protocols.

Table 4 - Enabled Protocols

Enabled Protocol Files Obtained From Host/Loader

XMOP Xyplex loader MOP VAX/VMS host RARP, BOOTP, DTFTP UNIX host

Displaying the Software Load Host

Use the SHOW/MONITOR SERVER STATUS command to display the name and location of the software load host if the access server obtained the software load image from the network.

Displaying the Parameter Server

Use the SHOW/LIST/ MONITOR PARAMETER SERVER command to display the name and location of the parameter server.

By default, all available dump protocols and parameter file protocols are enabled, and all available software load image protocols are enabled except DTFTP. Table 5 lists the available protocols for each process.

0038

Software Load Image Parameter File Dump file

CARD (default) XMOP MOP BOOTP RARP

NVS (default) XMOP MOP BOOTP RARP

XMOP MOP BOOTP RARP

DTFTP*

*Not enabled by default.

The access server first attempts to load software from the flash card using the CARD protocol, because this is the default. If a card is not present, it searches for the load image using protocols in the order in which they appear on the screen: XMOP, MOP, BOOTP, RARP, and DTFTP, if it is enabled. When the access server attempts to send information to a dump server, it first attempts to use XMOP, then MOP, BOOTP, and RARP.

Directed Trivial File Transfer Protocol (DTFTP)

The DTFTP (Directed Trivial File Transfer Protocol) information display on the screen only when DTFTP is listed as an Image load method. (Typically, you only need to use this when loading across a router or when the load host does not support BOOTP or RARP.) Similarly, the CARD/XMOP/ MOP load filename is present when CARD, XMOP, or MOP is listed as an Image load method.

0038

Using the CARD, NVS, XMOP and MOP Protocols

The access server uses the CARD, NVS, XMOP, and MOP protocols to search for a software load image or parameter file on a particular location determined by the protocol.

NOTE: The CARD and NVS protocols do not apply to dump files,

Page 90

Getting Started with MAXserver Access Servers

because NBase-Xyplex flash cards do not function as dump servers due to size limitation. The NVS protocol is also not applicable to load image files.

The XMOP and MOP Protocols

The XMOP and MOP protocols look for a software load image file, a parameter file, or a dump server. The access server first attempts to use XMOP and then MOP. The XMOP and MOP protocols can send diagnostic information to a dump server.

The Xyplex Maintena nce Operations Protocol (XMOP) looks for the files on a Xyplex loader on the network. See the Software Installation Guide for Xyplex Loader Kits for more information about how to use XMOP.

The Digital Equipment Corporation Maintenance Operations Protocol (MOP) looks for software load image and the parameter file on a Digital Equipment Corporation host running the MOP protocol. The access server can also use MOP to send information to a dump server. See the Software Installation Guide for VMS Kits for information about how to configure a MOP host.

Modify Unit Configuration

The Modify Unit Configuration option is where you can:

Change how the unit loads its software

Change the name of the load image that it requests, if any

Change how the unit requests parameter service and dumps memory

Specify the total configured memory

Enable/disable load status messages

return to the Modify Unit Configuration Menu.

Page 92

Getting Started with MAXserver Access Servers

‘N

’ - Disables the specified initialization configuration and lets you create your own configuration. See “Creating a Customized Configuration” to continue.

Creating a Customized Configuration

This section explains how to create a custom configuration for the MAXserver access server. You can customize the following values for up to three initialization records:

Enable all image loading types or only specific methods (e.g., CARD,

DTFTP, RARP)

Enable all parameter loading methods or only specific parameter loading

methods (e.g., NVS, XMOP, MOP)

Enable all dumping methods or only specific dumping methods (e.g.,

XMOP, TFTP, BOOTP)

Define a load file name (if you selected Card, XMOP or MOP loading

methods)

Define IP addresses for the unit, host and gateway (if you selected TFTP

as the loading method)

Defining the Image Loading Method

You can change the method the MAXserver uses to load its software. For example, you can configure the unit to load exclusively from a specific type of load server or from the flash card only. Use the Access server Configuration menu to change the software loading method. Alternatively, you can use DEFINE SERVER commands to change the software loading method. (See Command Line Interface section of this guide for a description of the commands you can use at the

Defining Parameter Loading Methods

This section describes how to specify the unit’s parameter loading methods. All MAXserver units are configured at the factory to store configuration data (parameters) locally in Non-volatile storage (NVS). Alternatively, you can use DEFINE SERVER commands to change the parameter loading method. See the Commands Reference Guide for a complete listing of DEFINE SERVER commands.

As an option, you can configure the unit to load parameters from a network host, called a parameter server, using the Access server Configuration Menu.

Once you have selected the image loading methods and pressed Return, the unit displays the following prompt:

Enable ALL methods for parameter loading (Y,N) [Y]?

‘Y’ - All methods are selected.

0038

‘N’ - You can select specific method(s). The configuration menu prompts:

Defining The CARD/XMOP/MOP Image Filename

Page 98

Getting Started with MAXserver Access Servers

This section describes how to define the image filename if you selected CARD, XMOP or MOP as the loading method. Once you have selected the dumping methods and pressed RETURN, the unit displays the following prompt (if you selected CARD, XMOP or MOP as the unit’s loading method).

CARD/XMOP/MOP IMAGE FILENAME (16 CHARACTERS MAX) [XPCSRV20]:

1. Enter a file name or a numerical value. The valid responses are as follows:

Valid filenames

Valid filenames consist of up to 16 characters, which can be letters and numbers, the underscore character (_), the hyphen character (-), and the period (.) character. The default load file name is XPCSRV20. (The actual name of the load file is XPCSRV20.SYS.)

Numerical Values

In place of a filename, you can specify a numerical value. A numerical value specifies to a Xyplex loader (another unit which has a flash card and the proper load image, or a MAXserver Manager card) that it should determine the appropriate load file based on:

The requesting unit's hardware type, or

A node entry in the client database of a Xyplex loader.

You can also use numerical values to specify that a MOP (Maintenance Operations Protocol) loader is to determine the appropriate load file based on information contained in the NCP (Network Control Program) database.

0038

Page 99

Getting Started with MAXserver Access Servers

Valid numerical values consist of the pound-sign character (#) and a number in the range of 0 through 128. Xyplex load servers respond to the numbers 1 through 5. The following table describes these values.

Table 10 - Image File Naming Conventions

Numerical Value Description

1 Allows you to specify a load file name via the NCP

commands at a VAX/VMS load server, or via client entries on a Xyplex loader. This is the default.

2 through 4 Reserved for use by NBase-Xyplex

5 Requires a load server to ignore the load request --

unless the load server's client database contains a node entry for the requesting access server. (The numerical value 5 is useful when you want to require that a specific load server be used to load the unit.)

6 through 128 Undefined.

0038

2. Enter a valid filename and press RETURN. The unit returns you to the Access server Configuration Menu. This completes the configuration of the access server.

3. If you enabled all image loading protocols or specified TFTP as the loading protocol, proceed to “Defining IP Addresses.”

Defining IP Addresses

If you enabled all image loading protocols or specified DTFTP as the loading protocol, you must supply a non-zero Internet address for the unit, load host and gateway (if the load host is not on the same network as the unit.
