Preparing for installation
Safety recommendations
To avoid any equipment damage or bodily injury caused by improper use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible
hazardous condition.
General safety recommendations
• Take adequate safety measures to avoid injury and switch damage. For example, wear an ESD
wrist strap.
• Make sure the ground is dry and flat and anti-slip measures are in place.
• Keep the chassis clean and dust-free.
• Do not place the switch on a moist area and avoid liquid surrounding the switch.
• Keep the chassis and installation tools away from walk areas.
• Move the switch and heavy components (such as the power supplies or chassis) with other people
rather than doing that alone.
Electricity safety
• Clear the work area of possible hazards, such as ungrounded power extension cables, missing
safety grounds, and wet floors.
• Locate the emergency power-off switch in the room before installation. Shut the power off at once in
case accident occurs.
• Unplug all the external cables (including power cords) before moving the chassis.
• Do not work alone when the switch has power.
• Always check that the power has been disconnected.
ESD prevention
To prevent the electronic components from being damaged by the electrostatic discharge (ESD), follow
these guidelines:
• Ground the switch correctly. For how to ground your switch, see "Installing the switch."
• Always wear an ESD wrist strap when installing components, especially the electronic printed circuit
boards.
• Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
• Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the range
of 1 to 10 megohm (Mohm) between human body and the ground.
To attach the ESD wrist strap:
1
1. Wear the wrist strap on your wrist.
2. Lock the wrist strap tight around your wrist to keep good contact with the skin.
3. Insert the ESD wrist strap into the ESD socket on the switch chassis.
Make sure the ESD wrist strap is correctly grounded.

Examining the installation site
The HP 12500E Routing Switch Series can only be used indoors. To ensure that th e switch works corre ctly
and to prolong its service lifetime, the installation site must meet the following requirements:
Weight support
Make sure the floor can support the total weight of the rack, chassis, cards, power supplies, and all other
components. Additionally, the floor loading plan must also consider system expansion, such as adding
more cards.

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling,

electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To
prevent EMI, take the following actions:
• 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.
• Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or
overcurrent caused by lightning strikes.
Grounding
Using a good grounding system to protect your switch against lightning shocks, interferences, and ESD
is essential to the operating reliability of your switch.
Make sure the resistance between the chassis and the ground is less than 1 ohm.
Power supply
To meet the power supply requirements:
1. Calculate the system power consumption.
2. Select power modules according to the system power consumption and power supply mode.
3. Verify that the power source on the installation site meets the requirements of the power modules.
For the power consumption and power module specifications of the switch, see "Appendix A Technical
specifications."
Cooling
Plan the installation site for adequate ventilation.
• Leave at least 10 cm (3.94 in) of clearance around the air intake vents and exhaust vents.
• Equip a good cooling system for the cabinet to install the switch.
• Equip a good cooling system for the installation site.
Figure 2, and Figure 3 sho
To ensure normal operation of the switch, make sure the maximum output power of the power
modules is greater than the system power consumption of the switch (reserve certain power for
redundancy). After determining the system power consumption and power supply mode (AC or
DC power supply), you can select power modules as needed.
Make sure the power source of the installation site is steady and can meet the requirements of the
power modules, including the input method and rated input voltage.

Installation preparation
Confirm the following preparations before starting installation:
19
A
• The rack is sturdy and securely grounded.
• There is sufficient clearance of 0.8 m (2.62 ft) around the rack for heat dissipation and installation.
• There is no debris inside or around the rack.
• The total height of the switches to be installed is no higher than the height of the rack and enough
clearance is reserved for cable routing.
• Make sure the clearance above the slide rail is sufficient for the switch and the slide rails can
support the weight of the switch. For the dimensions and weight of the 12500E switch, and the
weight of the hardware components, see "Appendix A Technical specifications."
Installing slide rails and cage nuts to the rack
Before installing the switch in the rack, secure slide rails to the rack. Besides slide rails, you can use a rack
shelf to support the switch. This document describes how to install slide rails only.
To ensure correct installation, use industry-standard slide rails or rack shelves. Slide rails or rack shelves
are not provided with the switch. HP recommends that you order HP slide rail LSTM2KSGD0. The slide
rail can be used in racks where the distance between the front and rear rack posts is in the range of 500
mm to 800 mm (19.69 in to 31.50 in).
Installing slide rails
If the rack has slide rails, skip this section.
The appearance and installation methods of slide rails depend on the slide rail types.
This section uses a 19-inch rack as an example to describe the installation procedures. The rack unit (RU)
(44.45 mm, or 1.75 in) measures the height of rack posts. As shown in Figure 14, eac
h 1 RU has three
mounting holes with center-to-center separations of 15.88 mm (0.63 in), 15.88 mm (0.63 in), and 12.70
mm (0.5 in). When installing the slide rails, make sure the bottom edge of the slide rails aligns with the
middle of the narrowest separation between mounting holes.
To install the slide rails:
1. Mark the position of the slide rail on the rack posts. Make sure the bottom edge of the slide rails
or rack shelf aligns with the middle of the narrower metal area between holes as shown in Figure
14.
TIP:
total of six screws are required within the 2 RU of installation space for each side of the slide rail.
You can mark the position for the top cage nut only.
20
Figure 14 Locating the installation position of the slide rails

2. Install the cage nuts on the rack posts.
a. Insert the upper ear (callout 1 in Figure 15) of a cage
nut into the corresponding installation
hole.
b. Push the cage nut to lead its lower ear (callout 2 in Figure 15) into th
e same hole.
c. Repeat steps a and b to complete installation of 24 cage nuts on the rack post. (Six cage nuts
for each rack post.
Figure 15 Installing the cage nuts
3. Align the screw holes on the two sides of the right slide rail (marked with F/R) with the marked
holes on the right rack posts, and then fasten the screws.
21
Figure 16 Fastening the screws
4. Use the same method described in step 3 to install the left slide rail to the left rack posts.
Keep the two slide rails at the same height so that the switch can be placed evenly.
Figure 17 Slide rails installed correctly
Installing cage nuts
Before mounting the chassis to the rack, install cage nuts to the front square-holed brackets of the rack.
22
g
To install cage nuts to the rack:
1. Align the mounting bracket with the left rack post, making sure its bottom edge and the slide rail
are level. Mark the positions of the cage nuts on the rack post according to the mounting holes on
the mounting bracket. (Each mounting hole on the mounting bracket corresponds to one cage nut.)
NOTE:
The mounting brackets are fixed on the chassis of the 12508E and 12518E before delivery from the
factory. To determine the installation holes for cage nuts, you can remove a mountin
bracket from
the chassis and mark the nut holes, or use a pattern tool to record the installation holes of the
mounting brackets and mark the nut holes accordingly.
2. Install cage nuts to the rack posts using the method described in relevant steps in "Installing slide
rails."
