· When stacking devices, maintain at least 1.5 cm of vertical spacing between them.
Mounting the device in a standard 19-inch rack
Restrictions and guidelines
· If you install the device in a standard 19-inch rack, ensure a distance of 1U (44.45 mm, or 1.75 in) between the chassis and other devices.
· Because the device is heavy, we recommend using the front mounting ears together with the tray, or using both the front and rear mounting ears together to safely support the device's weight.
· To avoid bodily injury or device damage, use a minimum of two persons to rack-mount the device.
Procedure
Unpack the device and accessories.
Use the mounting ear to align with the front Rack post to determine the cage nut installation position. At the same horizontal level as the bottom of the front mounting ear, use the rear mounting ear to mark the cage nut position on the rear Rack post with a marker, then install the cage nut at the mark.
To install the front mounting ears, use the supplied M4 screws to fasten the left and right front mounting ears to the left and right sides of the device faceplate.
To install the rear mounting ears, use M5 screws to mount the left and right rear mounting ears on the cabinet's rear Rack post.
Install the device into the cabinet, placing the rear end of the device onto the rear mounting ears.
Use a Phillips screwdriver to turn the M5 screws clockwise to secure the device's left and right front mounting ears to the cabinet's front Rack post.
Connecting the grounding cable
· Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. To install and use the device, first connect the grounding cable for the device reliably.
· Connect the grounding cable to the grounding strip in the equipment room. Do not connect it to a fire main or lightning rod.
You can ground the device by connecting it to the cabinet's grounding screw; ensure the cabinet is well grounded. If the installation environment has a grounding bar, the other end of the grounding cable can connect directly to the grounding bar. This document uses cabinet grounding as an example only.
Remove the grounding screw from the device chassis.
Place the OT terminal of the supplied yellow-green grounding cable over the chassis grounding screw.
Install the grounding screw into the device's grounding hole and tighten it with a Phillips screwdriver.
Remove the nut from a grounding post on the grounding terminal.
Tighten the other end with a nut.
Install optional accessories
Install interface module (optional)
No interface modules are provided with the device. Prepare them yourself as required.
Installation steps are as follows:
Face the front panel of the device.
Use a Phillips screwdriver to turn the thumb screws on the blank panel counterclockwise and remove the blank panel.
Slowly slide the interface module horizontally along the slot guide rails into the slot.
Use a Phillips screwdriver to turn the interface module's thumb screws clockwise to tighten them.
Install network port surge protector (optional)
· The network port surge protector applies only to 10M/100M/1000M copper interfaces (using RJ-45 connectors) of Ethernet ports.
· Network port surge protectors are not supplied with the device; users can purchase them as needed.
When the device is used in a server room and an external network cable enters the device, insert a network port surge protector in series with the signal line before it reaches the device's network port to prevent lightning damage.
Procedure
Peel off the protective paper from one side of the double-faced adhesive tape (user-supplied) and stick the tape to the surge protector's housing; then peel off the other side of the tape and stick the surge protector to the device chassis. Mount the surge protector as close as possible to the device's grounding screw.
Shorten the surge protector's ground lead according to the distance to the device's grounding screw, and firmly fasten the ground lead to the device's grounding screw; make sure the device's grounding screw is properly grounded.
Use a multimeter to check that the surge protector's ground lead makes good contact with the device's grounding screw and chassis. The measured resistance should be close to 0 ohm; gently tug the wire to confirm it is secure.
According to the surge protector's manual, connect the surge protector using a network port adapter cable (pay attention to orientation: connect the external cable to the IN side and the adapter cable to the device to the OUT side), and observe whether the interface module indicator LEDs display normally.
For the surge protector's technical specifications and installation and maintenance instructions, see the surge protector documentation.
Installation restrictions and guidelines
The following installation issues can affect the performance of the network port surge protector; please pay attention:
The surge protector was installed in the wrong direction. The correct connection is: "IN" to the external cable, "OUT" to the device's network port.
Poor grounding of the surge protector. The protector's ground lead should be as short as possible to ensure good contact with the device's grounding screw. After connecting, verify with a multimeter.
Incomplete installation of the surge protector. When more than one external network cable enters the device from other equipment, install surge protectors on all external network ports to provide protection.
Install AC power surge protector (optional)
Power surge protectors are not supplied with the device; users can purchase them as needed.
When the AC power cable is brought in from outdoors directly to the device's AC power input, use an external surge protection power strip for the AC input to prevent lightning damage. The surge protection power strip can be fixed to the cabinet, workbench, or server room wall with cable clamps and screws. In use, the AC power enters the surge protection power strip first and then flows to the device.
Figure 2-2 Power surge protector diagram
When you configure the recording mode, follow these restrictions and guidelines:
Table 1 When using a power surge protector, ensure its PE terminal is grounded.
Table 2 After plugging the device's AC power plug into the power surge protector (surge protection power strip) outlet, the surge protector provides lightning protection only when the green RUN indicator is on and no red alarm light is lit.
Table 3 Treat any red alarm on the power surge protector seriously and address it; correctly determine whether the ground is improperly connected or the live and neutral conductors are reversed.
You can use a multimeter to measure the polarity at the surge protector's power outlet. The specific method is as follows:
· If the outlet shows neutral on the left and live on the right (when facing the electrical outlet), it indicates the PE terminal of the power surge protector is not connected to earth ground.
· If it is not neutral-left/live-right, first check whether the AC electrical outlet connected to the power surge protector has reversed polarity. Open the power surge protector and correct the wiring polarity. If the red light still alarms afterward, the PE terminal is indeed not connected to earth ground.
Connecting Ethernet cables
Connecting an Ethernet copper port
You can use either a straight-through or a cross-over network cable to connect an Ethernet copper port.
To connect an Ethernet copper port:
Connect one end of the Ethernet cable to an Ethernet copper port on the device, and the other end to an Ethernet copper port on the peer device.
