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.

2
•
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 "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 2 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)

3
Substance Concentration limit (particles/m3)
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 3.
Table 3 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.
Laser safety
WARNING
!
•
The switch is a Class 1 laser device.
•
Do not stare into any fiber port when the switch has power
. The laser light emitted from the optical
fiber might hurt your eyes.
Installation tools
No installation tools are provided with the switch. Prepare the following tools yourself:
•
Phillips screwdriver.
•
ESD wrist strap.

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
12 to Figure 17.
NOTE:
Attach
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.
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.
As a best practice, use the primary grounding point or auxiliary grounding point 1 because the
grounding cable and grounding screw that come with the switch are suitable only for these two
grounding points.
To use auxiliary grounding point 2 on the HPE 5950 4-slot switch, prepare a grounding cable
yourself.
This section uses the primary grounding point on the HPE 5950 32QSFP28 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. See Figure 18.

Attaching the slide rails to the rack
The procedure is the same for attaching 1U and 2U slide rails to the rack. This section uses the 1U
slide rails as an example.
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 one slide rail with the cage nuts in a rear rack post, and use screws
(user-supplied) to attach the slide rail to the post, as shown in Figure 19.
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.

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 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.
The rack-mounting procedures are the same for the HPE 5950 48SFP28 8QSFP28 and HPE 5950
32QSFP28 switches. The following figures use the HPE 5950 32QSFP28 switch as an example.
