QPRJ-MSC, "3 + 1" 3@10/100Mbps RJ45 and 1@100Mbps Fiber SC Multimode Connector,
5.2.7
"Combo" Quad-Port Module
The QPRJ-MSC "3+1 Combo" quad-port supports three
auto-negotiating twisted pair ports at 10/100Mbps FDX / HDX, and
one fiber port with 100Mbps multimode FX SC connector. The
three RJ45 ports on the right operate the same as those in the
same place on the QPM- module.
The fiber SC connector functions as a fiber optic
transceiver to support 100BASE-FX network segments. When
installed in a Quad-Series Fiber Switch, it supports fiber cable
distances up the IEEE-standard 100Mbps distance limits, i.e.,
typically 2km at full duplex and 412m at half-duplex. The factory
default setting is for full-duplex operation, and a jumper on the
module must be moved to select half-duplex. (See Section 3.4).
Each 3+1 combo port has an Activity (ACT) LED indicating packets being received, a Link (LK)
LED that indicates proper connectivity with the remote device when lit, a FDX/HDX LED to indicate full-
duplex mode when lit (or half-duplex when off). In addition, the RJ45 ports have a "speed" LED-indicating
100Mbps when lit (or 10Mbps when off). The fiber port is always 100Mbps speed.
5.2.8
QPRJ-MST, "3 + 1" 3@10/100Mbps RJ45 and 1@100Mbps Fiber ST Multimode Connector,
"Combo" Quad-Port Module
The ProSwitch QPRJ-MST is also a 3+1 Combo quad-port. It is the same as the QPRJ-MSC
"3+1 combo" module except the multimode fiber port is ST-type. See Section 5.2.1 for a description of the
100Mbps multimode-mode fiber SC-type port.
5.2.9
QPRJ-SSC, "3 + 1" 3@10/100Mbps RJ45 and 1@100Mbps Fiber SC Singlemode Connector,
"Combo" Quad-Port Module
The ProSwitch QPRJ-SSC is also a 3+1 Combo quad-port module. It is the same as the QPRJ-
MSC "3+1 combo" module except the fiber port is singlemode. See Section 5.2.3 for a description of the
100Mbps singlemode fiber port.
5.2.10 QPM-FP
The QPM-FP is a blank face plate or cover plate that must be
installed in any empty QPM slots to maintain proper cooling air flow, and for
safety, etc.
Two screws underneath the front panel hold the QPM-FP in place.

TROUBLESHOOTING
All ProSwitch Ethernet products are designed to provide reliability and consistently high
performance in all network environments. The installation of ProSwitch Quad-Series switches is a
straightforward procedure (see Sections 3); the operation is also straightforward and is discussed in
Sections 4.
Should problems develop during installation or operation, this section is intended to help locate,
identify and correct these types of problems. Please follow the suggestions listed below prior to
contacting your supplier. However, if you are unsure of the procedures described in this section or if the
ProSwitch Quad-Series product is not performing as expected, do not attempt to repair the unit; instead
contact your supplier for assistance or contact Waters Communications Customer Support.

1. If difficulty is encountered when installing or operating the unit, refer back to the Installation
Section of the applicable chapter of this manual. Also check to make sure that the various components of
the network are inter-operable.
2. Check the cables and connectors to ensure that they have been properly
the cables/wires have not been crimped or in some way impaired during installation. (About 90% of
network downtime can be attributed to wiring and connector problems.)
3. Make sure that an AC power cord is properly attached to each ProSwitch
unit. Be certain that each AC power cord is plugged into a functioning electrical outlet. Use the PWR
LEDs to verify each unit is receiving power.
4. If the problem is isolated to a network device other than the ProSwitch Q-
it is recommended that the problem device be replaced with a known good device. Verify whether or not
the problem is corrected. If not, go to Step 5 below. If the problem is corrected, the ProSwitch Quad-
Series Switch and its associated cables are functioning properly.
5. If the problem continues after completing Step 4 above, contact your supplier of the ProSwitch
Quad-Series unit (or if unknown, contact Waters Network Systems) by fax, phone or email for assistance.
