Serial P or t Connections (COM1, COM2) T wo 9-pin male DE-9P connectors with IBM PC A T compatible pinouts are provided for connection to printers using serial ports.
USING THE HUB: Overview 19 USING THE HUB Overview The M208 W orkgroup Hub/Print Server includes a fully managable and intelligent eight port Ethernet hub . Hubs (or multi-port repeaters) are stable network de vices that perform signal regeneration (including amplification, symmetry , and retiming), packet forwarding, and routing.
20 USING THE HUB: Hub Installation • full hub monitoring capabilities using the npsh command set, • remote network management via pri v ate MIBs: the M208’ s pri vate MIB file contains all the .
USING THE HUB: Hub Configuration 21 Figure 3: T wisted-P air Cable Pinouts Hub Configuration The hub component of the M208 becomes fully operationable as soon as the unit is po wered up and thus very little configuration is required.
22 USING THE HUB: Hub Configuration ured on the unit. Configuring the M208 with an IP address There are a number of ways to configure the M208 with an IP address, either automat- ically with a shell script or manually .
USING THE HUB: Hub Configuration 23 T o disable link integrity on a specific port, please follo w the steps below: 1 Login to the M208 as a root user . 2 At the npsh prompt, type the following command: config hub [ portnum ] [-]li where portnum is the number between 1 and 8 of the port that you want to disable link integrity .
24 USING THE HUB: Monitoring the Hub If you are using the A UI port without an external transcei ver , the SQE T est can be used to verify the inte grity of the connection. T o enable the SQE T est on port 9, please follo w the steps below: 1 Login to the M208 as a root user .
USING THE HUB: Monitoring the Hub 25 Hub Monitoring Using npsh The command set npsh provides extensi v e information re garding the operation of the hub including both the general operational status of the hub as well as information specific to each port.
26 USING THE HUB: Monitoring the Hub Collisions Displays the number of occurrences where the port has acti vity on both its receiv e and transmit pairs. This is a normal e vent within a CSMA/CD network. Excessi ve collisions, ho wev er , may indicate an ov er- loaded network or a wiring error .
USING THE HUB: Monitoring the Hub 27 Readable Frames Displays the number of v alid frames receiv ed by the port. Readable Octets Displays the number of v alid octets receiv ed by the port. Rx P olarity Reversed Displays whether the recei ve polarity has been auto- matically re versed on the port.
28 USING THE HUB: SNMP Management Features SNMP Management Features The M208 includes a pri vate Management Information Base (MIB) file that contains a number of v ariables and traps that can be used to configure, monitor and manage all aspects of the unit.
USING THE HUB: Troubleshooting the Hub 29 • If you plug another hub into one of the RJ45 ports (Hub to Hub) and the LED does not turn on, try plugging it into port one and setting the selector switch to the straight-through position (||). If this works, either use port one or change to a crossed-ov er cable.

M208 INTERNAL ARCHITECTURE: Overview 89 unit host M208 INTERNAL ARCHITECTURE Overview This chapter will provide a more detailed description of the internal operating archi- tecture of the M208 including: destinations, models, v ariables, logpaths, and I/O ports.
90 M208 INTERNAL ARCHITECTURE: Models unit host Models Each destination on the M208 also has a model associated with it. The six models (one per destination) can be thought of as a series of mini-filter that can do special process- ing to the print job data.
M208 INTERNAL ARCHITECTURE: Variables 91 unit host V ariables V ariables are actually utilized within the M208’ s models and are useful for defining lengthy header or trailer strings. This might be necessary for certain printer switch strings, for example.
92 M208 INTERNAL ARCHITECTURE: Logpaths unit host Logpaths The term logpath comes from the UNIX syslog logging system. W ith the M208, each destination can report statistics on: user , page count, job name, and printer errors. In addition, a checksum calculation can be obtained to confirm data integrity when a job is sent to the printer .

The M208 allo ws just that through logpaths or through a backchannel method.
USING THE M208’S ADDITIONAL OPTIONS: TCP/IP Options 135 Lp Method The M208 provides its o wn version of the lp print command. This is used in conjunc- tion with rsh/rcmd/r emsh within an interface script or directly from the command line on the host.
136 USING THE M208’S ADDITIONAL OPTIONS: TCP/IP Options T wo methods are av ailable for doing this: 1 physically moving jumpers inside the Print Serv er, 2 issuing a command on the M208 and rebooting. Either way will produce an M208 that has all of the network settings it came with originally .
