Console description

The active500EM has a RJ-45 serial console port for local and telnet
configuration. The console port supports asynchronous mode. To achieve
asynchronous mode, set the data bit as 8, the stop bit as 1, the parity bit as
none, and the default baud rate as 9600bps.

In addition, the baud rates supported by the console port under Bootrom
mode includes 14400, 19200, 38400, 57600, and 115200(bps). The setting
will not take effect until after the switch is rebooted.

Back panel

The active500EM has one 100-240V 50/60Hz 5A AC power receptacle,
one standby DC power receptacle (48V), one ground connection, and two
expansion slots.

Status LEDs

The active500EM includes 24 port LEDs, power LED, AC power LED, system
automatic diagnoses LED, and 1/2 state LED of the extended module.

Environmental requirements

• The switch must be installed in a clean area; otherwise, the switch may
be damaged by electrostatic adherence.

• The switch must be maintained within system specifications.

• Ensure sufficient spacing around the switch for good air circulation.

• Avoid placing the switch in direct sunlight. Keep the switch away from
heat sources and strong electromagnetic interference sources.

2

• The switch must be mounted to a standard 19’’ rack or placed on a
clean, level desktop.

• The switch must be installed near an accessible power socket outlet.
When using DC input power, please make sure that a 4A circuit breaker
is used and is available near the controller installation site for easy
power off.

• The switch can be installed at a maximum altitude of 7,000 feet (2km).

• The DC power supply is screwed directly into the back of the
active500EM, creating a permanent connection. Therefore, an
appropriate disconnect device should be provided externally to the
active500EM in the case an urgent shutdown is required. The following
types of disconnect devices can be used:

• The main supply plug on the power supply cord.

• An appliance coupler.

• An isolating switch.

• A circuit-breaker.

• Any equivalent device.

Security warnings

• Do not place anything on top of the switch.

• Do not install, move, or relocate the switch and its modules when the
switch is in operation.

• Do not open the switch shell.

• Do not drop metals into the switch. This can cause the switch to short­circuit.

• Do not touch the power plug or power socket.

• Use standard power sockets, which have overload and leakage
protection.

• Have the emergency power switch on site. In case of emergency, switch
off the power immediately.

Preventing electrostatic discharge damage

CAUTION: Improper power supply system grounding,
extreme fluctuation of the input source, and transients (or
spikes) can result in larger error rate or hardware damage.

Electrostatic discharges (ESD) can cause damage to internal circuits and
the entire switch, and may cause physical injury. To avoid ESD damage:

• Ensure proper grounding of the device.

• Perform regular cleaning to reduce dust.

• Maintain proper temperature and humidity.

• Always wear an ESD wrist strap and antistatic uniform when in contact
with the switch.

Installation notice

• Read the instructions carefully before installation and operation. Prepare
installation materials, tools and installation site.

• Use the brackets and screws provided in the accessory kit with the proper
tools to perform the installation. Always wear an antistatic uniform and
ESD wrist straps. Use standard cables and connectors.

• Clean the site after installation, and ensure the switch is well grounded
before powering on.

CAUTION: Potential risks include: electric leakage, power
supply arcing, power line breakage, overloaded circuit, and
electrical short circuit. If electrical shock, fire, or electrical
short circuit occurs, cut off electricity and seek help.

Device installation

Required tools

• Screwdrivers, both Phillips (crosshead) and Standard (flat-head)

• ESD wrist strap & antistatic uniform

Installing the switch

To mount the active500EM on the 19’’ rack:

1. Attach the two brackets on the active500EM with screws provided in the
accessory kit.

2. Put the bracket-mounted switch into a standard 19’’ rack. Fasten the
active500EM to the rack with the screws provided. Leave enough space
around the switch for good air circulation.

CAUTION: The brackets are used to mount the switch to the
rack, and are not load-bearing. Place a rack shelf under the
switch. Do not place anything on top of the switch. Do not
block the vents on the switch to ensure the proper operation.

Connecting the console

The active500EM provides a serial console port.

To connect the console to the active500EM Access Control switch:

1. Attach the console cable (included) end to the console port of the
switch.

2. Connect the other side of the console cable to a COM port .

3. Turn on both the switch and the COM port, and configure the switch
through the COM port.

Copper cable cable connection

1. Insert one end of the Ethernet cable into the RJ-45 Ethernet port in the
switch copper port.

2. Insert the other end of the Ethernet cable into the RJ-45 Ethernet port
of the other device.

3. Check all status indicators for the corresponding ports; a lit LED
indicates that the link has been established. Otherwise, the link is not
ready and the cable should be examined.

CAUTION: Verify the label above the port before
connecting cables. Connecting to the wrong port may
damage the switch.

AC power supply connection

1. Insert one end of the power cable (included) into the power source
socket, and the other end into a standard power socket.

2. Check if the power status indicator in the front panel of the switch is
lit. The active500EM is self-adjustable for the input voltage. When the
input voltage is in the range printed on the switch surface, the switch
can operate correctly.
