needed for installation.
Safety recommendations
General safety recommendations follow:
Turn off all power and remove all power cables before opening the chassis.
Unplug all power and external cables before moving the chassis.
Before installation, locate the emergency power switch so that you can shut off power immediately if
necessary.
Always wear an ESD-preventive wrist strap when installing the device.
Do not stare into an open optical interface. The light can cause permanent eye damage.
Use a good grounding system. This is essential for reliable operation.
Confirm that the resistance between the chassis and the ground is less than 1 ohm.
Installation site requirements

Cooling
Air flows through the A-MSR20 from left to right, as shown in Figure 7.
Figure 7 A-MSR20 ventilation
To prevent overheating:
Provide adequate clearance for air flow.
Provide at least 10 cm [3.94 in] ventilation space around the router's air intake and outlet vents.
For heat dissipation and device maintenance, the front and rear of the rack should be at least
0.8 m (2.62 ft) away from walls or other devices.
The equipment room ceiling height should be no less than 3 m (9.84 ft).
Make sure the site has an adequate cooling system.
Lightning protection
To protect the router from lightning:
Make sure the grounding cable of the chassis is grounded properly.
Make sure the grounding terminal of the AC power receptacle is grounded properly.
Install a lightning arrester at the input end of the power supply.
Install a lightning arrester at the input end of outdoor signal lines (for example, E1/T1 line) to which
the router’s interface modules are connected.

Rack-mounting requirements
Before rack-mounting a switch, make sure the rack meets the following requirements:
Size. The rack must be appropriately sized to hold the switch.
Ventilation. HP recommends that you mount a switch in an open rack. If you mount a switch in a
closed rack, provide an adequate heat dissipation system. With either type of rack, there must be
enough space around the switch's left and right panels for unimpeded airflow and heat dissipation.
Sturdy support. The rack must provide steady, secure support for the switch and accessories.

Take measures to protect the power system from the
power grid system.
Keep the protection ground of the router as far away
from the grounding device or lightning protection

install the router in a closed cabinet, make sure that the
cabinet is equipped with a good ventilation system.
The rack is sturdy enough to support the weight of the
router and accessories.
The size of the cabinet is appropriate for the router.
The front and rear of the cabinet are at least 0.8 m
(31.50 in) away from walls or other devices.
Safety
precautions
The router is far away from any sources of heat or moisture.
The emergency power switch in the equipment room is identified and
accessible.

Installation accessories supplied with the router are ready.
User-supplied tools are ready.
Reference
Documents shipped with the router are available.
Online documents are available.

WARNING!
To avoid injury, do not touch bare wires, terminals, or parts with high-voltage hazard signs.
NOTE:
The barcode on the router chassis contains important product information that you must provide to HP Support
before returning a faulty router for service.
The HP tamper-proof label attached to a mounting screw on the router chassis must be kept intact. Before
opening the chassis cover, contact HP Support for authorization; if you do not, you take full responsibility for all
operation and maintenance failures.

To install the router on a workbench:
1. Make sure the workbench is clean, stable and properly grounded.
2. Place the router upside down on the workbench and attach the rubber feet to the four round holes
in the chassis bottom.
3. Place the router upright on the workbench.

Grounding the router
The grounding resistance should be less than 5 ohms.
If the router is mounted in a 19-inch standard rack, the rack must be properly grounded.
You can ground the router in one of the following ways, depending on the grounding conditions at the
installation site:
Ground the router to a properly grounded grounding strip.
Ground the router to a grounding conductor buried in the earth.
Grounding the router to a grounding strip
To connect the grounding cable, as shown in Figure 13:
1. Remove the grounding screw from the rear panel of the router chassis.
2. Put the OT terminal of the supplied grounding cable on the grounding screw.
3. Use a screwdriver to fasten the grounding screw, with the grounding cable OT terminal attached,
to the grounding screw hole.
