KVM over IP Switch Energy Intelligence PDU

Q1: How do I select the KVM over IP switch? Q1: When is Energy Intelligence PDU required?

A1: First, you need to confirm the number of servers and remote active sessions. The number of servers will A1: Power stability and energy efficiency are critical for data center management. ATEN Energy

user’s needs, such as KN2132VA (2:32), KN1116V (1:16) or KN4164V (4:64). If we are able to
define the tender specifications, KN2140VA (2:40) or KN4140VA (4:40) are recommended.
Q2: How to choose between eco PDU and Energy PDU?

Q2: How do I choose the right KVM adapter cables?
A2: eco PDU is equipped with network feature for metering and switching the power distribution
over the network. Energy PDU is a budget-friendly solution without the built-in network feature.
A2: The number of servers is the same as the quantity of KVM adapter cables. You must choose If the over IP feature is required, the Energy Box can be added to provide the over IP capability to

required by the user, such as virtual media, smart card reader and audio etc.
(Refer to the KVM Adapter Cable Compatibility List for more information)
Q3: How to estimate the scale of eco PDU for the entire data center?

Serial Console Server A3: eco PDUs need to be deployed for all IT racks, power distribution cabinets (PDC), server racks,
core network racks and storage machine racks etc. planned for the data center that uses AC
power supply. If the data center uses A/B type power supply, then two power strips are required

devices in a data center. You can estimate the number of serial consoles based on those serial
devices mentioned above. Additionally, if Cisco Data Center Multi-Tier Model is applied, you can
estimate the number of serial devices separately by Core layer, Aggregation layer and Access layer, A4: eco PDU can basically be divided into 1U and 0U. 1U is designed for level installation. 8-outlet
and plan the required volume of serial console ports separately for each layer. is the major specification of 1U eco PDU which is commonly adopted by the market. 0U is
designed for vertical installation. The major specification of 0U is 24-outlet. When the total power
consumption of the rack cabinet is over 10KW, it is suggested to deploy two 30A eco PDUs at the

According to different countries, NEMA and IEC socket configuration are available for selection.
A2: System reliability is critical for data centers, we suggest selecting the models with dual power Firstly, confirm the power P designed for the IT rack; the input current of eco PDUs A = P ÷ 220V.
supplies and dual Ethernet ports, such as SN0108A, SN0116A, SN0132 and SN0148. For example, Next, confirm the number and type of IT rack equipment. If large power (for example, ≧ 2000W)
if there are 20 serial devices (Router, Switch and etc.) in the data center, SN0132 or SN0148 are IT equipment such as blade servers or small machines are deployed in the racks, then intelligent
recommended to fulfill this use case.
power strips with C19 output port must be selected. The number of output ports per power strip
must be greater than the number of IT equipment planned to be deployed for the rack. If not,
Q3: How to select the serial adapters (RJ-45 to DB9/DB25) for the various serial devices? please contact ATEN solution division of the product department for technical support.

A3: ATEN provides SA series adapters to connect the serial console server to serial devices with
different connector types (ex. DB9 or DB25). To select the suitable adapters, you need to confirm if
their serial devices work as a DTE or DCE role in the serial communication. If you can use a straight
cable to successfully connect the device to the SN series serial console server, the device works as a
DCE role. If you need a NULL modem cable to connect the serial device, the serial device works as a
DTE role. After the role of DTE/DCE of the serial device is confirmed, you can select the suitable
adapter according to the connector type (9 pin or 25 pin, Male or Female) of you serial device.

Q4: Could we recommend KA7140 and KN series KVM over IP switches instead of SN series serial
console server?

A4: Yes, if the serial devices are less than 6.
