Safety Instructions
When a connector is removed during installation, testing, or servicing, or when an energized fiber is
broken, a risk of ocular exposure to optical energy that may be potentially hazardous occurs,
depending on the laser output power.
The primary hazards of exposure to laser radiation from an optical-fiber communication system are:
Damage to the eye by accidental exposure to a beam emitted by a laser source.
Damage to the eye from viewing a connector attached to a broken fiber or an energized fiber.

Rack Mounting
When mounting the switch, practice good safety habits. Relay rack mounting normally requires at
least two people.
1. Obtain the tools required for the mounting hardware.
2. Attach the mounting brackets to the switch by using the screws in the accessory kit.
3. From the front of the relay rack, position the switch in its relay rack mounting location.
4. Secure the switch in its relay location on both left and right side of mounting bracket.

Ground Connecting
MLB-E42XX-28 must be properly grounded for optimum system performance.
Alarm Relay Connecting
The alarm relay output contacts with current carrying capacity of 30VDC, 1Aare a 2P terminal
block.
The alarm relay contact is “Normal Open”, and it will be closed when detected any power failures.
Power Connecting
DC Power Connection
The switch can be powered from two power supply (input range 12V –58V). The DC power
connector is a 4Pterminal block; insert the positive and negative wires into V+ and V- contact on the
terminal block and tighten the wire-clamp screws to prevent the wires from being loosened.
After completing chassis installation, please apply power to the fused power distribution panel
feeding the chassis.
Note
The DC power should be connected to a well-fused power supply.

AC Power Connection
If you use AC power, connect the AC power cord to the AC supply socket on the rear panel, and
plug the cord into the external power source. The voltage must be 100 to 240 V (±10% tolerance).
Warning:
Ensure that all power sources to the chassis (power distribution panel) are turned off
during the connection.
Ethernet Interface Connecting (RJ45 Ethernet)
MLB-E42XX-28 provides two types of electrical (RJ45) and optical (mini-GBIC) interfaces.
Connecting the Ethernet interface via RJ45:
To connect to a PC, use a straight-through or a cross-over Ethernet cable,
To connect the switch to an Ethernet device, use UTP (Unshielded Twisted Pair) or STP
(Shielded Twisted Pair) Ethernet cables.
Ethernet Interface Connecting (Fiber, SFP)
For a 1000 Mbps fiber port available, please use the mini-GBIC SFP. These accept plug in fiber
transceivers that typically have an LC style connector.
For a 100 Mbps fiber port (port 25 & 26 only) available, please prepare the LC connectors or SC
connectors (with the use of an optional SC-to-LC adapter).
They are available with multimode, single mode, long-haul or special-application transceivers.
DANGER:
Never attempt to view optical connectors that might be emitting laser energy.
Do not power up the laser product without connecting the laser to the optical fiber
and putting the cover in position, as laser outputs will emit infrared laser light at this
point.

Console Connection
The Console port is for local management by using a terminal emulator or a computer with terminal
emulation software.
DB9 connector connect to computer COM port
Baud rate: 115200bps
8 data bits, 1 stop bit
None Priority
None flow control
To connect the host PC to the console port, a RJ45 (male) connector-to-RS232 DB9 (female)
connector cable is required. The RJ45 connector of the cable is connected to the CID port of
MLB-E42XX-28; the DB9 connector of the cable is connected to the PC COM port. The pin
assignment of the console cable is shown below:
