Figure 3.6 Combo ports, RJ45 and
fiber internal jumper settings.
Note:
Be certain that the main power is
disconnected before opening the unit or
changing any internal jumper settings
The factory (default) setting is Auto-
negotiation on all RJ45 ports and full duplex on
fiber 100Mbps ports, which is generally
popular. Auto-negotiation on RJ45 and FDX on
fiber port works well under most
circumstances, but cannot always be
depended upon to work as expected. If full-
duplex will not function properly in your setup,
internal jumpers allow the speed and mode of
the Q-Series Combo- quad ports to be fixed,
even if the attached device may or may not
support full-duplex. This is desirable when
there are unknown devices presently or
potentially connected, which will not operate
correctly with full duplex or half-duplex.
Examples include hubs that support only half-
duplex by default.
If auto-negotiation will not function
properly in your setup, internal jumpers allow the speed and mode of the Q-Series RJ45 (copper) quad-
ports to be fixed, even if the attached device may or may not support auto-negotiation. This is desirable
when there are unknown devices presently or potentially connected, which will not operate correctly with
auto-negotiation. Examples include some NICs and most Media Converters.
3.7 Fiber 10Mb ports, internal jumper settings for 10Mb fixed Half- or Full Duplex at all ports
The factory (default) setting is
for half-duplex on all fiber 10Mbps
ports, which is generally popular. HDX
works well under most circumstances.
If half-duplex on 10Mbps will not
function properly in your setup, internal
jumpers allow the duplex mode of the
Q-Series fiber quad- ports to be
changed, even if the attached device
supports full-duplex. This is desirable
when there are devices connected
which will not operate correctly with
half-duplex. Examples include switches
that support full duplex only.
Therefore, the default setting
of half-duplex (fiber ports) is generally
desirable as it is widely used and
allows for the connection of various
devices without re-configuration (where
the connected device is half duplex and does not support full duplex i.e. hub and media-converters).

ProSwitch Quad-Series Fiber Switches
Installation and User Guide
Page 15
Note:
For 10Mbps fiber ports, the user can set the jumpers either at full duplex or half duplex on all the
four ports. There are no individual port duplex options for 10Mbps ports.
Note:
Be certain that the main power is disconnected before opening the unit or changing any internal
jumper settings
3.8
Powering the ProSwitch Quad-Series Switch
The ProSwitch Quad-Series switches incorporate an internal universal power supply, and has a
recessed male IEC connector for the AC power cord at the left-rear. A manual power ON-OFF switch is
adjacent. A six-foot 115 VAC 60 Hz standard power cord is supplied with each unit shipped within the
United States and Canada.
The auto-ranging power supply supports installation environments where the AC voltage is from
90 to 260 volts with a power input frequency of between 47 and 63 Hz. The 8-port units will typically
consume fewer than 20 watts of power, and the 16-port units will typically consume about 35 watts.
When connecting the Ethernet cabling, there is no need to power down the unit. Individual
segments can be connected or disconnected without concern for AC power-related problems or damage
to the unit.
Power supply options are available to suit the Quad-Series switches to special high-availability
communications and/or heavy industrial-grade applications, including:
•
48VDC with single DC input,
•
48VDC with dual-source DC input,
•
48VDC with dual redundant internal power supply units and dual-source DC input,
•
AC with dual redundant internal power supply units and dual-source AC input

Quad Port Module (QPM) Installation
The ProSwitch Q-Series fiber switches are normally received from the factory with all required
QPM modules installed. There may be situations where QPM cards need to be added or replaced. In
cases where additional QPM cards are needed, the faceplate for an available front-mounted slot must be
removed. The following procedure describes this operation.
3.9.1 Preparation for Installing and Removing QPMs
STOP!!!
Be sure the power cord is unplugged from the chassis before attempting to remove and/or
replace any QPM cards. Failure to do so may result in damage to the unit and will void the
warranty.
Caution- Avoid Static Discharge: The port modules (like most electronic equipment) are sensitive
to static discharge. Use proper ESD measures when handling port modules.
Step 1
Make sure the QPM Card package has all necessary accessories to install it properly. The QPM
card package for field installation comes along with a QPM card, two 7/16 stand-offs, two #4-40
pan-head screws, two #4-40 black color flat-head screws and two headers pin.
Step 2 Remove Chassis Cover
The ProSwitch Q-Series chassis are combined with top and bottom part and assembled together
with the help of 20 Philips head screws. There are 7 screws located on front-top of the unit and three
screws each on the left and right edges. Remove these screws. Once these are removed, the top cover
is easily lifted off the chassis base. When the chassis top cover has been removed, the interior of the unit
is exposed.
