2.3.5 Battery String Storage batteries store electricity. When the mains and D.G. fails, storage batteries supply DC power for the uninterruptible power supply (UPS). Then the DC power is inverted by the UPS into AC power for loads. Battery strings with different capacity are used based on the capacity of the UPS. In the medium modular data center, a battery string consists of forty 120 V valve-regulated lead acid batteries and provides a capacity of 40 Ah, 65 Ah, 100 Ah, or 150 Ah. To extend battery service life, it is recommended that storage batteries work under a temperature ranging from 15°C to 25°C. Dedicated hydrogen exhaust devices must be provided to exhaust hydrogen generated by storage batteries in the medium modular data center.

2.4 Cooling System Based on the maximum power (4 kW or 7kW) consumed by each cabinet for heat dissipation, the Cooling system supports high-end and low-end configurations, meets T1 and T3 condition requirements, and works with 380 V 50 Hz or 60 Hz power supplies,In the 380 V 60 Hz scenario, air conditioners are purchased locally.
Overview The medium modular data center consisting of high-density cabinets has great sealing performance. In normal cases, the temperature of air exhausted from air conditioners is higher than the dew-point temperature, and humidity in the medium modular data center changes slightly. Therefore, only some air conditioners are required to provide the humidification function. Low-density power consumption cabinets apply to small- and medium-sized enterprises and offices that have low requirements for services, installation environments, and sealing performance. To meet requirements of these small- and medium-sized enterprises and offices, only Ordinary precision air conditioning are required. Air conditioners are powered by dedicated UPSs. Air conditioners work in N+1 redundancy mode based on IT cabinets, the number of cable distribution cabinets, and the power (4 or 7 kW) consumed by each cabinet for heat dissipation. 1.
Maximum power of 7 kW consumed by a single cabinet for heat dissipation In-row air conditioners and cabinets form hot and cold confined aisles to isolate hot air from cold air. Air flows in from the rear and flows out from the front. Specifically, air conditioners cool hot air from servers and generate cold air for servers. Because in-row air conditioners are close to heat sources, the air supply distance greatly decreases, which improves the cold air utilization.
2.
Maximum power of 4 kW consumed by a single cabinet for heat dissipation This design involves high-end configurations and low-end configurations.
Issue 02 (2013–03–28)
a.
In high-end configurations, in-row air conditioners are used to meet high requirements for e-government networks and educational and financial organizations. In-row air conditioners and cabinets form hot and cold confined aisles to isolate hot air from cold air. If the medium modular data center is compact, it does not need to be sealed.
b.
In low-end configurations, common precise air conditioners are used to meet smalland medium-sized enterprise requirements. Air conditioners are vertical to servers, and aisles are not confined.

Description
Monitoring index
Monitoring indexes vary according to monitoring resources. For example, the NetEco monitors cabinets and power supplies and calculates their utilization rates. You can change the alarm thresholds based on which the NetEco generates an alarm and determines the alarm severity.
Alarm threshold
A specific value of a monitoring index. The NetEco generates an alarm when the monitoring index is higher or lower than this value. An alarm threshold helps you determine whether a device is working properly. If an alarm is generated, you need to rectify the fault. After the monitoring index returns to the normal range, the alarm will be cleared. The upper alarm threshold should be a little lower than the critical value (and vice versa) so that problems can be detected in advance.
Latest monitoring data

A confined aisle may negatively affect the gas fire extinguishing system. Therefore, for a data center with an existing fire extinguishing system, unconfined aisles are preferred. Figure 2-26 shows a single-row cabinet equipment room (with unconfined aisles) utilizing the existing fire extinguishing system. In this scenario, four IT cabinets are provided. Figure 2-26 Utilizing the existing fire extinguishing system for a single-row cabinet data center(with unconfined aisles)
Equipment Room Without Fire Extinguishing System A fire extinguishing system, including a smoke sensor, a temperature sensor, and a gas fire extinguishing system, must be installed after single-row or dual-row cabinets are installed. Figure 2-27 shows the fire extinguishing system for a single-row cabinet equipment room (with unconfined aisles). Figure 2-28 shows the fire extinguishing system for a dual-row cabinet equipment room (with unconfined aisles). Figure 2-29 shows the fire extinguishing system for a single-row cabinet equipment room (with confined aisles). In these scenarios, four IT cabinets are provided. The fire extinguishing system layout for a dual-row cabinet equipment room with confined aisles is similar to that for a single-row cabinet equipment room with confined aisles. Fires may emerge from inside the medium modular data center (for example, IT cabinets) or outside (for example, cables at the top). It is recommended that fire detection and extinguishing systems be installed both inside and outside the medium modular data center. The installation positions are determined by site conditions. If fire detection and extinguishing systems are installed only outside the medium modular data center due to certain factors, the performance of the systems may be degraded. The materials for a fire extinguishing system should be purchased from the local market. The entire system, including the sensors, alarm system, and heptafluropropane fire extinguishing system (not controlled by the NetEco), should be installed onsite and comply with related regulations and standards.

Heptafluoropropane Fire Extinguishing System (Not Controlled by the NetEco) A gas fire extinguishing system used for the mini data center is not controlled by the NetEco. It consists of an extinguishing agent vessel, an inlet pipe, a pressure sensor, and a electromagnetic valve driver. A heptafluoropropane fire extinguishing system is recommended. The heptafluoropropane fir extinguishing system provides a smoke sensor and a temperature sensor. It allows you to install a fire extinguishing controller on a cabinet or outside the protection zone as required. A fire in an equipment room generates a lot of smoke and increases the ambient temperature. Then the smoke sensor and temperature sensor send fire signals to the fire extinguishing controller. The fire extinguishing controller generates a large-power current to start the electromagnetic valve and open the extinguishing agent vessel in the heptafluoropropane fire extinguishing cabinet. Then extinguishing agent sprays into the protection zone. Figure 2-30 shows a heptafluoropropane fire extinguishing cabinet that uses an integrated gas fire extinguishing controller. An emergency startup/shutdown button, an audible and visual alarm, and a gas release indicator are installed around the data center entrance. When the smoke sensor sends an alarm signal, the audible and visual alarm generates an audible and visual alarm signal. After the smoke sensor and temperature sensor generate alarm signals, the gas fire extinguishing controller sends a signal for releasing the gas within 30 seconds and turns on the gas release indicator after the gas release action is detected.

2.7.2 Integrated Cabling Layout Principles Cable trays are used to route power cables and signal cables and enable separate management for Strong electric and weak electric cables. There are cables holes in the middle of each cabinet top. The cable trays can be extended and provide upper and lower channels for power cables and signal cables respectively when power cables and signal cables intersect. Red cable troughs are used by power cables, and green cable troughs are used by signal cables. There are cable binding holes at skylight ceiling joints. Figure 2-31 shows how to route power cables and signal cables. Figure 2-31 Routing power cables and signal cables
Integrated Cabling An integrated cabling cabinet is installed between the data center and network cable distribution compartment to aggregate upstream signal cables of server cabinets, as shown in Figure 2-32.
