Preparing for installation
Overview
The HP A10500 Switch Series includes these models: A10504, A10508, and A10508-V.
Safety recommendations
W
ARNING!
Read all of the safety instructions in the
Compliance and Safety Gui de supplied with your device before
installation and operation.
This section provides general recommendations. For more information see the Compliance and Safety
Guide included with your device.
•Turn off all the power and remove all the power cables before opening the chassis.
•Unplug all power and external cables before moving the chassis.
•Locate the emergency power off switch before installation and shut off power immediately if
necessary.
•Always wear an ESD-preventive wrist strap when installing the device.
•Do not stare into the open optical interface; the high power density light can burn the retina.
•Use a good grounding system to protect your router against lightning shocks, interferences, and
ESD; this is essential to the operating reliability of your switch.
•Make sure that the resistance between the chassis and the ground is less than 1 ohm.

Rack-mounting requirements
Before rack-mounting a switch, make sure the rack meets the following requirements:
•HP recommends that you mount a switch in an open rack. If you mount a switch in a closed rack,
make sure there is a good heat dissipation system.
•The rack is steady enough to support the switch and accessories.
•The switch fits the rack size. Leave some space beside the left and right panels of the switch for
chassis heat dissipation.

Confirming installation preparations
Before installing the switch:
•You have read the chapter “Preparing for installation” carefully and the installation site meets all
the requirements.
•A 19-inch rack is ready for use. For how to install a rack, see the rack installation guide.

5
•The rack is sturdy and securely grounded; the installation position on the rack is appropriate for the
chassis; no debris exists inside or around the rack.
•The switch is ready for installation and has been carried to a place near the rack and convenient
for moving.
•Keep the packages of the switch and the components for future use.
Installing slide rails and cage nuts on the rack
Installing slide rails
If the rack has slide rails, skip this section.
Installation may vary with different rack types.
For the slide rails, HP recommends that you order the HP X421 A-Series Chassis Universal 4-Post Rack
Mounting Kit (JC665A). For more information about the kit, see the chapter “Appendix B FRUs and
compatibility matrixes.”
To install a slide rail:
1. Read the signs on the slide rail (see Table 7) to avoid making a mistake. Check that the slide rails
can support the weight of the switch. For the weights of the switches, see the chapter “Appendix A
Technical specifications.”

F/R Front end of the right slide rail Mount this end to the front right rack post.
2. Mark the position on the rack for installing the slide rail. To ensure the stability of the rack, mount
the switch at the lowest possible position. To mount multiple switches on the rack, mount the
heaviest switch at the bottom of the rack.
a. Position the chassis of the switch according to its height. For specifications, see the chapter
“Appendix A Technical specifications.”
b. Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area
between holes, as shown in Figure 5.
c. Each rack post requires six screws to attach the slide rail. You only need to mark the uppermost
square hole and lowermost square hole for installation.
d. Mark the square holes at the same height on the other three rack posts.
NOTE:
One rack unit has three holes, the middle of which is an auxiliary installation hole, and the other two
are standard installation holes. You can distinguish them by the space between each two holes. The
space between a standard installation hole and an auxiliary installation hole is larger than that
between two adjacent standard installation holes.

higher than the available installation height of the rack, and reserve enough clearance for cable
routing.
Installing mounting brackets and cable management brackets
Before installing the switch to the rack, install the cable management brackets and mounting brackets
shipped with the switch. Cable management brackets (signal cable and power cable management
brackets) are used for cabling the switch, and mounting brackets are used for attaching the chassis to
the rack.
Installing the cable management brackets
You must install the signal cable management brackets separately for the A10508-V switch. All other
A10500 switches come with the signal cable management brackets secured to the mounting brackets. In
this step, you only need to install the power cable management brackets for them.
•The A10508-V has two cable management brackets—the signal cable management brackets are
installed at the upper part of the switch, and the power cable management brackets are installed at

10
the lower part of the switch. They are installed in the same way. For more information, see Figure
10.
•The power cable management bracket installation procedure for the A10508 is the same as
A10508-V.
•The power cable management brackets of the A10504 have a slightly different structure, and
installed in a similar procedure. For more information, see Figure 11.
To install a cable management bracket:
1. Unpack the cable management brackets.
2. Attach the cable management bracket to the chassis, and align the screws with the screw holes on
the chassis, as shown in Figure 10.
3. Fasten the screws.

Installing mounting brackets
Before installing the switch to the rack, install the mounting brackets to the chassis. Marks L and R are
printed inside the mounting brackets to distinguish between the left and right mounting brackets. To
install the mounting brackets, face the front of the switch, and mount the left and right mounting brackets
to the two sides of the switch, as shown in Figure 12.

Mounting the switch to the rack
CAUTION:
•Do not hold the handle of the fan tray, power supply, or the back cover of the chassis, or the air vents
of chassis. Any attempt to carry the switch with these parts may cause equipment damage or even
bodily injury.
•After placing the switch on the slide rails, do not let go immediately because this may tip the switch,
and damage the switch or even cause bodily injury.
To mount the switch to the rack:
1. Move the chassis to face the rear of the chassis towards the front of the rack.
2. Use at least two people to lift the switch by using the handles or supporting the bottom of the
chassis until the bottom of the switch is a little higher than the slide rails on the rack. HP
recommends using a mechanical lift for moving your switch.
3. Place the switch on the slide rails and slide the switch along the slide rails until the mounting
brackets on the switch touch the front rack posts, as shown in callout 1 on Figure 13.
4. Attach the chassis to the rack with mounting screws.

NOTE:
If the screw holes on the mounting brackets cannot align with the cage nuts on the rack, check that the
bottom edge of the slide rail aligns with the middle of the narrower metal area between holes and that
the cage nuts are installed in the correct holes.

Grounding the switch
CAUTION:
Before using the switch, connect the grounding cable properly to guarantee lightning protection and
anti-interference of the switch.
Grounding the switch with a grounding strip
CAUTION:
•Use the supplied grounding cable (yellow-green grounding cable).
•Connect the grounding cable to the earthing system in the equipment room. Do not connect it to a
fire main or lightning rod.
When a grounding strip is available at the installation site, connect the grounding cable through the
grounding strip.
To connect the grounding cable:
1. Unpack the grounding cable. The grounding cable provided with the switch is compliant with the
NEBS standards.
2. Remove the grounding screws from the grounding holes at the rear of the chassis, as shown in
callout 2 on Figure 14).
3. Fasten the grounding screws, which are attached with the dual-hole terminals of the grounding
cable, into the grounding holes of the chassis.
4. Connect the OT terminal of the grounding cable to the grounding post of the grounding strip, and
fasten the grounding cable to the grounding strip with the hex nut.

Grounding the switch through the PE wire of an AC power
supply
If the switch is AC powered and no grounding strip is available at the installation site, you can ground
the switch through the PE wire of the AC power supply, as shown in Figure 15.
Make sure that the AC power supply uses a three-wire cable with a protection wire, and the PE wire of
the AC power supply is well grounded at the power distribution room or AC power supply transformer
side. In addition, make sure that the PE connector on the switch is well connected to the PE wire of the
AC power supply.

Installing modules
There is no required order for installing modules. HP recommends you to install the modules needed,
and then connect the power cord.
TIP:
Keep the packages of the switch and the components for future use.
Attaching an ESD-preventive wrist strap
Every switch provides an ESD-preventive wrist strap. To minimize ESD damage to electronic components,
wear an ESD-preventive wrist strap and make sure it is well grounded when installing modules.
To use an ESD-preventive wrist strap:
1. Make sure the switch is well grounded. For how to ground your switch, see the chapter “Installing
the switch.”
2. Put on the wrist strap.
3. Tighten the wrist strap to keep good skin contact. Make sure that the resistance reading between
your body and the ground is between 1 and 10 megohms.
4. As shown in Figure 16, insert the ESD-preventive wrist strap into the ESD port on the switch chassis,
or attach it to the grounding screw of the chassis with an alligator clip.
