Rack Mount Safety Instructions
When installing the chassis in a rack, impleme nt the following safety instructions:
• Elevated Operating Temperature: If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient temperature. Therefore, consideration should
be given to installing the equipment in an environ m ent compatible with the
maximum ambient temperature (TA) of 40°C (104°F).
• Reduced Air Flow: Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation on the equipment is
not compromised.
• Mechanical Loading: Mounting of the equipment in the rack should be
such that a hazardous condition is not achieved due to uneven mechanical
loading.
• Circuit Overloading: Consideration should be given to the connection of
the equipment to the supply circuit and the effect that overloading of the
circuits might have on over-current protection and supply wiring.
Appropriate consideration of equipment nam eplate ratings should be used
when addressing this concern.
• Reliable Earthing: Reliable earthing of rack-mounted equipme nt should be
maintained. Particular attention should be given to supply connections
other than direct connections to the branch circuit (e.g., use of power
strips.)

5.2.2 Deployment of a Standalone De vice
The Ethernet ports on the E-SBC module operate in pairs to provide Ethernet port 1+1
redundancy. In each pair, one port serves as the active Ethernet port while the other as
standby. When the active port fails, the device switches to the standby Ethernet port. The
port pairs are shown in the figure below:
Figure 5-3: Ethernet Port Pairs
It is important that the two ports making up a pair are connected to different switches (but
in the same subnet). The figure below illustrates an example of implementing Ethernet-port
redundancy:

5.2.3 Deployment of Two Devices for High Availability
The device supports 1+1 high availability, whereby two devices are deployed and
connected to the same broadcast domain/s. In such a setup, the same Ethernet port-pair
redundancy setup is done for each device. For example, if port-pair 5 and 6 are used for
Device "A", then Device "B" must also use port-pair 5 and 6, as shown in the figure below:
Figure 5-5: Cabling for High Availability (Example)
In High Availability, the two devices interconnect through their Maintenance interfaces,
using the same Ethernet Port Group.
Note: For possible connections (including Tx / Rx settings) between the HA devices,
refer to the User's Manual.

sharing and redundancy. Each module provides an AC power socket on the
device's rear panel. If both power modules are used, ensure that you
connect each one to a different AC supply socket.
• The two AC power sources must have the same ground potential.
To connect the device to the power supply:
1. Connect the AC power cord (supplied) to one of the power sockets located on the rear
panel.
Figure 5-8: Connecting to Power
2. Connect the other end of the power cord to a standard AC electrical outlet (100-
240V~50-60 Hz).
3. For load sharing and power redundancy, repeat steps 1 through 2, but using the
power socket of the second Power Supply module and connecting this to a different
supply circuit.
4. Turn on the power at the power source (if required).
5. Check that the POWER LED on each Power Supply module (front panel) is lit green.

This allows optimal internal airflow pressure within t he chassis.
6.1.1 Grounding the Device
Before performing any maintenance procedures, ensure that your device is properly
grounded, as described in Section 5.1 on page 25.
6.1.2 Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) due to improper handling of the device's modules and
components can cause irreversible damage to the equipment. Adhere to the following
guidelines for preventing ESD:
When handling modules, always wear a grounded ESD wrist strap or ankle st rap at a
grounded work area to prevent ESD. Connect the equipment end of the strap to the
chassis ESD screw (described in the procedure below).
To prevent static electrical damage to the module, do not touch the electrical
components of the module. Instead, hold t he m odule only on the edges where no
electrical components are located.
Ensure that the modules are securely installed in the chassis.
To attach an ESD wrist strap to the chassis:
1. Attach the ESD wrist strap to your body (typically, the wrist) so that it is in direct
contact with your skin.
2. Attach the other end of the wrist strap (e.g., an alligator cl ip) to the ESD spring screw
located on the rear panel of the chassis, as shown below.
