Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.
· Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with wet cloth or liquid.
· Do not place the switch near water or in a damp environment. Prevent water or moisture from entering the switch chassis.
· Do not place the switch on an unstable case or desk. The switch might be severely damaged in case of a fall.
· Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction.
· Connect the yellow-green protection grounding cable before power-on.
· Make sure the operating voltage is in the required range.
· To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off.
· When replacing field replaceable units (FRUs), including power supplies and fan trays, wear an ESD wrist strap to avoid damaging the units.
Examining the installation site
The switch must be used indoors.
Mount your switch in a rack and verify the following items:
· Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
· The rack has a good ventilation system.
· Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into the switch from the cold aisle and exhausts to the hot aisle.
· Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the neighboring devices from entering the top device.
· The rack is sturdy enough to support the switch and its accessories.
· The rack is reliably grounded.
To ensure correct operation and long service life of your switch, install it in an environment that meets the requirements described in the following subsections.
Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
· Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of materials, and metal corrosion.
· Lasting low relative humidity can cause washer contraction and ESD and cause problems including loose mounting screws and circuit failure.
· High temperature can accelerate the aging of insulation materials and significantly lower the reliability and lifespan of the switch.
For the temperature and humidity requirements for the switch, see S6826 & S9826 Switch Series Hardware Information and Specifications.
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of metal components and contact points. In the worst case, this might shorten the device's lifetime and even cause communication failure. Table1-1 describes the dust concentration limits in the equipment room.

EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways:
· A conduction pattern of capacitance coupling.
· Inductance coupling.
· Electromagnetic wave radiation.
· Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
· If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid.
· Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices.
· Use electromagnetic shielding, for example, shielded interface cables, when necessary.
· To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route interface cables only indoors.

¡ To install the mounting brackets at the port-side mounting position, see Figure2-14, Figure2-15, Figure2-16, and Figure2-20.
¡ To install the mounting brackets at the power supply-side mounting position, see Figure2-17, Figure2-18, Figure2-19, and Figure2-21.
For the S6826-48Y8C switch, to install the mounting brackets at the power supply-side mounting position, use the four screw holes nearest to the power supply side. To install the mounting brackets at the network port-side mounting position, use the four screw holes nearest to the network port side.
2. Determine the chassis rail installation position:
¡ If the mounting brackets are installed at the power supply-side mounting position, install the chassis rails near the port side.
¡ If the mounting brackets are installed at the network port-side mounting position, install the chassis rails near the power supply side.
3. Place the chassis rail against the chassis side panel. Align the chassis rail installation holes with the screw holes. Use the provided M4 screws (recommended torque: 12 kgf-cm) to attach the chassis rail to the chassis. See Figure2-14 to Figure2-21.
You can use super-short slide rails and long chassis rails to rack-mount the S6826-48Y8C switch. Based on the rack depth, install the long chassis rails not reaching out of the chassis, as shown in Figure2-15 and Figure2-18 or reaching out of the chassis, as shown in Figure2-16 and Figure2-19.
|
|
NOTE: Secure the mounting brackets and chassis rails to both sides of the chassis in the same way. |
Connecting the grounding cable to the chassis
|
|
CAUTION: The primary grounding point and auxiliary grounding point are located on the left panel of the chassis. You must connect the grounding cable to the grounding point before you mount the switch in the rack. |
This section uses the primary grounding point on the S9826-32C switch as an example.
To connect the grounding cable to a grounding point:
1. Choose a grounding point as required.
This example uses the primary grounding point.
2. Unpack the grounding cable and grounding screws.
3. Use two grounding screws to attach the two-hole grounding lug of the grounding cable to the grounding holes at the grounding point. Use a screwdriver to tighten the screws (recommended torque: 20 kgf-cm). See Figure2-22.
Figure2-22 Attaching the grounding cable to the primary grounding point on the S9826-32C switch

1. Identify the slide rail installation position in the rack.
2. Install cage nuts (user-supplied) in the mounting holes in the rack posts.
3. Align the screw holes in one slide rail with the cage nuts in a rear rack post, and use user-supplied M6 screws to attach the slide rail to the post (recommended torque: 30 kgf-cm). See Figure2-23.
4. Repeat the preceding steps to attach the other slide rail to the other rear rack post.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.
Figure2-23 Installing the slide rails
Mounting the switch in the rack
This task requires two people.
To mount the switch in the rack:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Verify that the mounting brackets and chassis rails have been securely attached to the switch chassis.
3. Verify that the slide rails have been correctly attached to the rear rack posts.
4. Attach cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as the slide rails.
5. One person performs the following operations:
a. Supporting the bottom of the switch, aligns the chassis rails with the slide rails on the rack posts.
b. Pushes the switch slowly to slide the chassis rails along the slide rails until the mounting brackets are flush with the rack posts.
6. Another person uses user-supplied M6 screws (recommended torque: 30 kgf-cm) to attach the mounting brackets to the rack.
To secure the switch in the rack, make sure the front ends of the slide rails reach out of the chassis rails.
The rack-mounting procedures are the same for the S6826-48Y8C and S9826-32C switches. The following figures use the S9826-32C switch as an example.
Figure2-25 Mounting the S9826-32C switch in the rack (Port-side mounting position for the mounting brackets)
Grounding the switch
|
|
CAUTION: · Correctly connecting the grounding cable is crucial to lightning protection and EMI protection. · Do not connect the grounding cable to a fire main or lightning rod. · To guarantee the grounding effect and avoid switch damage, use the grounding cable provided with the switch to connect the switch to a grounding strip in the equipment room. |
The power input end of the switch has a noise filter, whose central ground is directly connected to the chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis ground to the earth so the faradism and leakage electricity can be safely released to the earth to minimize EMI susceptibility of the switch.
To ground the switch:
1. As shown in Figure2-26, attach the two-hole grounding lug of the grounding cable to a grounding point on the chassis. For more information, see "Connecting the grounding cable to the chassis."
The grounding point in Figure2-26 is for illustration only.
2. Remove the hex nut of a grounding post on the grounding strip.
3. Attach the ring terminal of the grounding cable to the grounding post on the grounding strip, and secure the ring terminal to the grounding post with the hex nut.
