Preparing for installation
The H3C S6890 Switch Series includes the following models:
•S6890-54HF
•S6890-30HF
•S6890-44HF
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 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 in the equipment room and make sure the air inlet and outlet vents of
the switch are not blocked.
•Make sure the input voltage for the power supply 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.
Make sure the installation site meets the following requirements:
•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 the temperature and humidity in the equipment room in the acceptable range.

2
•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 "Technical specifications."
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points, especially when indoor relative humidity is low. In the worst
case, electrostatic adsorption can cause communication failure.
Table 1 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m³)
Dust ≤3 x 104 (no visible dust on the tabletop over three days)
NOTE:
Dust diameter ≥5 μm
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 2.
Table 2 Harmful gas limits in the equipment room
Gas Maximum concentration (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
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.

3
Laser safety
WARNING!
•The switch is a Class 1 laser device.
•Do not stare into any disconnected fiber port or optical fiber. The laser light emitted from the fibe
r
port or optical fiber might hurt your eyes.

Attaching the mounting brackets and chassis rails to the
chassis
IMPORTANT:
M4 screws are used for attaching the mounting brackets and chassis rails to the chassis. As a best
practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten the M4 screws.
To attach the mounting brackets and chassis rails to the chassis:
1. Place the wide flange of the mounting bracket against the chassis side panel. Align the
mounting bracket installation holes with the screw holes in the chassis. Use M4 screws
(provided) to attach the mounting bracket to the chassis.
{To install the mounting brackets at the power supply-side mounting position, see Figure 9.
{To install the mounting brackets at the port-side mounting position, see Figure 10.
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 M4 screws (provided) to attach the chassis rail to the chassis. See Figure
9and Figure 10.
4. Attach the mounting brackets and chassis rails to the other side of the chassis in the same way.

Connecting the grounding cable to the chassis
CAUTION:
The primary grounding point and auxiliary grounding point 1 are located on the left panel of the
chassis. If you use one of these grounding points, you must connect the grounding cable to the
grounding point before you mount the switch in the rack.
The grounding cable and grounding screw that come with the switch are applicable to both the
primary and auxiliary grounding points.
To connect the grounding cable:
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. See Figure 11.
As a best practice, use a torque of 20 kgf-cm (1.96 Nm) to fasten the grounding screws.
Figure 11 Attaching the grounding cable to the primary grounding point on an S6890-54HF
switch
Attaching the slide rails to the rack
The installation procedure is similar for short and long slide rails. The following procedure uses long
slide rails as an example.

10
To attach the slide rails to the rack:
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 a slide rail with the cage nuts in a rear rack post, and use M6 screws
(user-supplied) to attach the slide rail to the post, as shown in Figure 12.
As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.
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 that the slide rails can slide into the chassis rails.
Figure 12 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 tasks:
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 screws (user-supplied) 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.

Grounding the switch
CAUTION:
•Correctly connecting the grounding cable for the switch is crucial to lightning protection and EMI
protection.
•As a best practice to guarantee the grounding effect, connect the grounding cable provided with
the switch to the 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.
NOTE:
The power and grounding terminals positions in the figures in this section are for illustration only.
CAUTION:
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a
fire main or lightning rod.
To connect the grounding cable:
1. 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."
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.

Installing and removing fan trays
CAUTION:
To ensure good ventilation of the switch, follow these guidelines to install and remove fan trays:
•The switch comes with the fan tray slots empty. Before powering on the switch, make sure all fan
tray slots have fan trays installed and the fan trays are the same model.
•Make sure all slots have a module or filler panel installed when the switch is operating.
•If multiple fan trays fail on an operating switch, do not remove the fan trays at the same time.
Replace the fan trays one after another and finish replacing a fan tray within 3 minutes.
The supported fan trays vary by switch model.
Installing a fan tray
CAUTION:
To prevent damage to the fan tray or the connectors in the chassis, insert the fan tray gently. If you
encounter a hard resistance while inserting the fan tray, pull out the fan tray and insert it again.
Multiple fan trays are available for the switch. Select fan trays for the switch as needed. For the
available fan trays and their specifications, see "Fan trays."
The installation procedure is the same for the fan trays. The following procedure installs an
LSWM1FANSA fan tray in an S6890-54HF switch.
To install a fan tray:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
