PSM-8E

USER’S GUIDE

Designed to be networked with TRANSITION Networks PowerStar

™

hubs, the TRANSITION Networks PowerStar Express Multiplexer (PSM-8E) is a site-configurable multiplexer used for extending IBM 5250* protocol network distances over fiber.

*IBM 5250 protocol products include the IBM®System 34, 36, 38, and AS/400, remote controllers, and many supporting devices manufactured by IBM and other companies.

The PSM-8E allows multiple AS/400, System 3x, or remote controller polling groups to be transmitted over a single fiber-optic pair, providing maximum throughput in either 1 Mb/s Optimized mode or in 2 Mb/s Express mode by transparently multiplexing the 5250 "split-polling" feature. (All new IBM controllers support "split-polling" as a means of achieving higher throughput rates, even when connected to standard legacy devices. The PSM-8E uses "split-polling" to increase performance up to four times over the standard legacy 1 Mb/s 5250 protocol.)

NOTE: Refer to IBM 5250 Express reference material available from network vendors when installing the PowerStar Express Multiplexer or PowerStar

™

in a 5250 Express network.

PSM-8E IN THE NETWORK

Install one host PSM-8E multiplexer and one or more device PSM-8E multiplexer(s) in the network to extend, over fiber, the distance between a AS/400, System 3x, or remote controller and 5250 protocol network devices.

A DB-25 connector at the back of the PSM-8E allows a single host PSM-8E connection to an AS/400 over twisted-pair cable.

Eight (8) RJ-45 connectors at the front on the PSM-8E allow a host PSM-8E connection to an AS/400, System 3x, or remote controller over twisted-pair cable (using RJ-45 connectors and baluns, with twinax “bricks” as necessary).

NOTE: The eight RJ-45 connections at the front of the PSM-8E are divided into two polling groups of four connections each. Polling group #1 is the set of connections labeled A and B and numbered 0-3. Polling group #2 is the set of connections labeled C and D and numbered 4-7. Ports within a polling group must be connected to ports from a common controller. (A major difference between the newer AS/400 work station controllers (WSC) and the older WSCs is the number of polling groups. The older WSCs had one polling group for all eight ports. The newer WSCs have two polling groups: ports 0-3 comprise one polling group and ports 4-7 comprise the other polling group.)

INSTALLATION

Optionally Modify Jumper Settings

Internal PSM-8E jumpers allow selection among three RJ-45 pin configurations (4 & 5, 3 & 6, 1 & 2) and the DB-25 connection. All PSM-8Es jumpers are factory configured and the factory setting is circled on an identification label located at the rear of the PSM-8E. If required at the installation site, these factory settings can be changed.

NOTE: The DB-25 and the RJ-45 jumper configurations are mutually exclusive. If any of the three RJ-45 options is selected, the DB-25 option is deselected. If the DB-25 option is selected, the RJ-45 options are deselected.

WARNING: Remove AC line cord from power source before modifying jumper settings. Failure to observe this warning could result in personal injury or death.

CAUTION: Wear a grounding device and observe electrostatic discharge precautions when modifying jumper settings. Failure to observe this caution could result in damage to, and subsequent failure of, the PSM-8E.

To modify the PSM-8E jumper settings:

1. Remove PSM-8E top cover.

• Remove and retain two (2) top cover screws located on rear panel.

• Gently slide top cover back one inch.

• Carefully tilt top cover up.

2. Locate eight (8) sets of jumpers positioned behind the eight (8) RJ-45 connectors.

3. Using small screwdriver or similar device and referring to drawing below, reconfigure jumpers as required.

NOTE: JUMPERS SETTINGS FOR ALL EIGHT (8) SETS OF JUMPERS MUST BE IDENTICAL.

4. Replace PSM-8E top cover:

• Carefully tilt top cover down.

• Slide top cover forward to align against bottom cover.

• Install two (2) retained top cover screws.

5. Do devices interfere with each other? YES

• Is there one and only one host-polling group per PSM-8E polling

group?

• Do all devices on star segments have unique addresses?

• Are all devices properly terminated?

• Contact Technical Support: (800) 260-1312.

• Continue at step 6.

6. Are devices able to operate in Express mode? NO

Note that the controller may have down-shifted to 1 Mb/s due to errors during installation. If this is the case, the controller will wait approximately one hour and then retry the Express mode.

• Are the host AND the device capable of Express mode?

• Do all inter-connecting components support the Express mode?

• Are all devices on the port Express ready?

• Are all cable distances within the Express specification?

YES

• Continue at step 7.

7. Do Express LEDs flash? YES

Note that if there are fewer than seven devices, the flashing Express LED is normal.

• Continue at step 8.

8. Are Express LEDs ON without data activity? YES

Note that If the host is disconnected during an Express connection, the Express LED remains on.

• Check host cables for proper connection.

• Contact Technical Support: (800) 260-1312.

grounded AC outlet?

• Does the grounded AC outlet provide power?

• Contact Technical Support: (800) 260-1312.

YES

• Continue at step 2.

2. Is the PSM-8E RX LED OFF or FLASHING? YES

• Are the fiber-optic connectors are properly connected?

• Have the fiber-optic budget and distance been exceeded?

• Continue at step 3.

3. Is the PSM-8E TX LED OFF? YES

• If problems persists, contact TRANSITION Networks Technical

Support.

• Continue at step 4.

4. Is a network device down or unstable? YES

• Is there one and only one host polling group per PSM-8E polling

group?

• Does the host device type match the device?

• Has the host work station controller (WSC) capacity been

exceeded?

• Is the device properly terminated using two 54.9 ohm resistors

located between the "A" phase pin & earth ground and the "B" phase pin & earth ground? NOTE: Termination is provided by a "Y" or "T" cable assembly or by a terminating balun (i.e. ASFT series).
