1.1.2 Chromebook Cart Side view Rear view Front view The Chromebook Carts main purpose is to charge and store all 41 Chromebooks when not in use. The top of the cart can also be used to store and power the Super Zoom, Content Delivery Appliance (CDA) and the Access Point. Power Power to the cart is provided by a single standard 13 amp plug and is therefore standard voltage. Each cart is fitted with a surge protector to avoid damage during lightning strikes or electrical surges. It is recommended that the cart should never be used without the surge protector being installed. Charging The cart has 3 trays on which Chromebooks can be placed on. Each tray can be turned on or off depending on which tray of Chromebooks are required to charge. Each tray can hold and charge a maximum of 14 Chromebooks. Mobility On the base of the cart are 4 lockable wheels that can be securely locked to avoid the cart moving when pushed.
1.1.3 Yes Super Zoom What is a Yes Super Zoom? The Yes 4G Super Zoom provides the Lab with high-speed 4G Internet connectivity. Unlike other Zooms the Super Zoom does not transmit a Wi-Fi signal directly to the Chromebooks. Instead, it acts as an Internet gateway, providing internet connectivity whenever the AP/CDA requires it. In the ChromeLab it is the Access Point that transmits the Wi-Fi signal to the Chromebooks not the Super Zoom. What do the LED indicators on the Super Zoom mean? 1. The top 5 LEDs represent 4G signal strength. 5 bars being strongest and 1 bar being low signal. If the lowest 4G LED blinks, it indicates that Zoom is not connected to Yes network. During a firmware update, these LEDs will blink in an up and down fashion. 2. The Wi-Fi LED indicator shows whether the Wi-Fi network is enabled. It will also blink when data is transmitted or received over Wi-Fi. 3. The Voice LED indicator shows whether voice service is available. It will blink when voice service is being used. 4. The LAN LED indicator shows whether a device is being connected via RJ-45 cable. It will blink when data is transmitted and received over LAN. 5. The Power LED indicates whether the modem is turned on. Yes Super Zoom FAQ s My 4G LED indicators are blinking in an up and down motion. What does that mean? 1. The Zoom is currently performing a firmware update over the air. The 4G LED indicators will return to their normal states when this is completed. It typically takes approximately 5 minutes or less depending on the Internet connectivity speed the Zoom is experiencing.
Does the Zoom have to be pointed to a particular direction for best 4G coverage and performance? 1. The Zoom is equipped with a multi-directional high gain antenna that allows it to be placed on any direction. For best performance, place the Zoom near any window. 1.1.4 Peplink Content Delivery Appliance (MFA 300) The Peplink media fast (MFA-300) is an all-in-one Video/Content Delivery Appliance (CDA) which helps cut huge upstream bandwidth usage and expenses while delivering video, learning apps, and other web-based instructional content for the mobile lab internet usage. It has an internal storage capacity of 250GB and will store content for 30 days. Deletion of content is by First in First Out whereby after 30 days the oldest content will be written over and replaced by newer content. The Content Delivery Appliance (CDA) reduces the usage amount of internet bandwidth required when browsing videos, learning apps or any web-based resources. For example, if a whole class wants to access an online video, the Cache Server will store the video in order to reduce bandwidth consumption and speed up the loading time. Peplink Content Delivery Appliance FAQ s What are the functions of the LED lights?

What is the difference between a LAN Port and a WAN Port? Generally speaking, the WAN port connects to the Internet, and the LAN port accommodates wired Ethernet computers. Both ports share these features: They accept standard RJ-45 Ethernet connectors. They are designed not to allow accidental insertion of an RJ-11 telephone connector. Note: Do not plug in anything to port 2 and 3. It may disturb the Mobile Lab Performance. What content cannot be cached? There are certain materials that the CDA will not store. These are: Live streaming video or audio streaming (live internet TV or internet radio). Data transmitted using https or other secured/encrypted connections like SFTP or VPN Any content that has not been fully downloaded previously. 1.1.5 Access Point (EnZGenius EAP600)
The EAP600 is a wireless-11n 600Mbps (300Mbps + 300Mbps) high power Dual Band concurrent Access Point. It allows simultaneous operation of a 2.4GHz and a 5GHz wireless network. The device is used to provide Wi-Fi access to the devices inside the ChromeLab. It supports up to 42 simultaneous connections for each ChromeLab. Access Point (EnZGenius EAP600) FAQ s What is the function of the LED indicator lights? NO. DESCRIPTION ACTION 1.

A surge protector is a device that shields computers and other electronic devices from surges in electrical power, or transient voltage, that flow from the power supply.
How does a Surge Protector work? A surge protector works by channelling the extra voltage into the outlet's grounding wire, preventing it from flowing through the electronic devices while at the same time allowing the normal voltage to continue along its path. Electrical surges can damage computer equipment by burning its wires or gradually over time wearing down the device's internal components. Surges can even wipe out any saved data. Surge protectors can also protect telephone and cable lines as these also carry electric current. How do I use the Surge Protector? Plug in the Surge Protector to your power source. Then plug in the main power plug of the ChromeLab cart to the Surge Protector. WARNING! It is your responsibility to ensure that the wires from the external power source to the Cart are properly insulated and earthed. The Surge Protector is not a failsafe. Lack of proper insulation and earthing could lead to electrocution even with the Surge Protector plugged in. 1.1.8 Headsets Each ChromeLab consists of 41 headsets. Headsets must be plugged into the 3.5mm combined headphone/microphone socket as shown below. Note: The headphones have a built in microphone. Audio volume is controlled using the Chromebook volume controls; there are no audio controls on the headsets.
