Step 1: Prepare the Site for MX104 Router Installation
Prepare your site for MX104 installation by observing the following guidelines:
You can install the router in a four-post rack or cabinet or an open-frame rack.
•
The rack rails must be spaced widely enough to accommodate the chassis's external dimensions: 6.125
•
in. or (15.55 cm) high, 9.5 in. (24.13 cm) deep, and 17.5 in. (44.5 cm) wide. The outer edges of the
mounting brackets extend the width to 19.2 in. (48.7 cm).
One person must be available to lift the router while another secures the router to the rack.
•
The rack must be strong enough to support the weight of the fully configured router, up to 32 lb (14.5 kg).
•
For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allow
•
at least 6 in. (15.2 cm) of clearance between side-cooled devices. Allow 2.8 in. (7 cm) between the side
of the chassis and any non-heat-producing surface such as a wall.
For service personnel to remove and install hardware components, there must be adequate space at the
•
front and back of the router. Allow at least 30 in. (76.2 cm) in front of the router and 24 in. (61 cm)
behind the router.
5
The rack or cabinet must have an adequate supply of cooling air.
•
Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet without recirculating
•
into the router.
You must install the router into a rack that is secured to the building structure.
•
Mount the router at the bottom of the rack if it is the only unit in the rack.
•
When mounting the router in a partially filled rack, load the rack from the bottom to the top with the
•
heaviest component at the bottom of the rack.
Install the router only in restricted areas, such as dedicated equipment rooms and equipment closets, in
•
accordance with Articles 110-16, 110-17, and 110-18 of the National Electrical Code, ANSI/NFPA 70.

Install the MX104 Router in the Rack
The router can be installed horizontally in a rack or cabinet.
Two people are required to install the MX104 router. The chassis weighs approximately 32 lb (14.5 kg).
To install the chassis (see Figure 3 on page 8):
1. Ensure that the rack is in its permanent location and is secured to the building. Ensure that the installation
site allows adequate clearance for both airflow and maintenance.
2. Position the router in front of the rack or cabinet.
3. Have one person grasp both sides of the router, lift the router, and position it in the rack, aligning the
mounting bracket holes with the threaded holes in the rack rails. Make sure the chassis is level.
4. Have the second person install a mounting screw into each of the open mounting holes aligned with
the rack, starting from the bottom.
5. Visually inspect the alignment of the router. If the router is installed properly in the rack, all the mounting
screws on one side of the rack should be aligned with the mounting screws on the opposite side, and
the router should be level.

•
Connect the Grounding Cable
You ground the router by connecting a grounding cable to earth ground and then attaching it to the chassis
grounding points on the front of the router. To ground the router:
1. Verify that a licensed electrician has attached the cable lug provided with the router to the grounding
cable.
2. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an approved
site ESD grounding point. See the instructions for your site.
3. Ensure that all grounding surfaces are clean and brought to a bright finish before grounding connections
are made.
4. Connect the grounding cable to a proper earth ground.
5. Detach the ESD grounding strap from the site ESD grounding point.
6. Attach an ESD grounding strap to your bare wrist, and connect the other end of the strap to an ESD
grounding point.
7. Place the grounding cable lug over the grounding points on the front of the chassis (see
Figure 4 on page 11).
8. Secure the grounding cable lug with the washers and screws. The holes are sized for SAE 10-32 screws.
Apply 4.34 lb-in. (0.49 Nm) of torque to each screw. Do not overtighten the screw. (Use a number 2
Phillips screwdriver.)
CAUTION: Ensure that each grounding cable lug seats flush against the surface of
the grounding points as you are tightening the screws. Ensure that each screw is
properly threaded into the grounding points. Applying installation torque to the
screw when improperly threaded may result in damage to the terminal.
10
CAUTION: The maximum torque rating of the grounding screws on the router is
4.34 lb-in. (0.49 Nm). The grounding screws may be damaged if excessive torque
is applied. Use only a torque-controlled driver to tighten screws. Use an
appropriately sized driver, with a maximum torque capacity of 5 lb-in. or less. Ensure
that the driver is undamaged and properly calibrated and that you have been trained
in its use. You may wish to use a driver that is designed to prevent overtorque when
the preset torque level is achieved.
9. Dress the grounding cable, and verify that it does not touch or block access to router components, and
that it does not drape where people could trip on it.

Connect MIC Cables to the MX104 Router
1. Have ready a length of the type of cable used by the component. For MIC cable specifications, see the
MX Series Interface Module Reference.
2. Remove the rubber safety plug from the cable connector port.
WARNING: Do not look directly into a fiber-optic transceiver or into the ends of
fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to a
transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when inserting
or removing a cable. The safety cap keeps the port clean and prevents accidental
exposure to laser light.
3. Insert the cable connector into the cable connector port on the faceplate.
NOTE: The XFP cages and optics on the components are industry standard parts that have
limited tactile feedback for insertion of optics and fiber. You need to insert the optics and
fiber firmly until the latch is securely in place.
14
4. Use the equipment frame to support cables and prevent them from dislodging or developing stress
points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess
cable out of the way in the cable routing channel.
CAUTION: Avoid bending a fiber-optic cable beyond its minimum bend radius. An
arc smaller than a few inches in diameter can damage the cable and cause problems
that are difficult to diagnose.
CAUTION: Do not let fiber-optic cables hang free from the connector. Do not
allow the fastened loops of a cable to dangle, which stresses the cable at the
fastening point.
Step 5: Connect Power to the MX104 Router
IN THIS SECTION

3. Remove the plastic cover protecting the terminal on the faceplate.
18
4. Verify that the DC power cables are correctly labeled before making connections to the power supply.
In a typical power distribution scheme where the return is connected to chassis ground at the battery
plant, you can use a multimeter to verify the resistance of the –48V and return DC cables to chassis
ground:
For –48V and –60V:
a. The cable with very high resistance (indicating an open circuit) to chassis ground is the DC input
cable (-).
b. The cable with very low resistance (indicating a closed circuit) to chassis ground is the return cable
(+).
For +24V:
a. The cable with very low resistance (indicating a closed circuit) to chassis ground is the DC input
cable (-).
b. The cable with very high resistance (indicating an open circuit) to chassis ground is the return cable
(+).
5. Remove the screws and washers from the DC terminals.
6. Secure each power cable lug to the terminal with the washers and screw (see Figure 11 on page 20).
Apply 27.4 lb-in. (3.1 Nm) of torque to each screw. Do not overtighten the screw. (Use a number 2
Phillips screwdriver.)
a. Secure the positive DC source power cable lug to the return (+) terminal.
b. Secure the negative DC source power cable lug to the input (–) terminal.
CAUTION: Ensure that each power cable lug seats flush against the surface of the
terminal block as you are tightening the screws. Ensure that each screw is properly
threaded into the terminal. Applying installation torque to the screw when
improperly threaded may result in damage to the terminal.
CAUTION: The maximum torque rating of the terminal screws on the DC power
supply is 27.4 lb-in. (3.1 Nm). The terminal screws may be damaged if excessive
torque is applied. Use only a torque-controlled driver to tighten screws on the DC
power supply terminals. Use an appropriately-sized driver, with a maximum torque
capacity of 27.4 lb-in. or less. Ensure that the driver is undamaged and properly
calibrated and that you have been trained in its use. You may wish to use a driver
that is designed to prevent overtorque when the preset torque level is achieved.
19
7. Replace the plastic cover over the terminals on the faceplate.
8. Connect each DC power cable to the appropriate external DC power source.
NOTE: For information about connecting to external DC power sources, see the instructions
for your site.
9. Switch on the external circuit breakers to provide voltage to the DC power source cable leads.
10. Repeat Step 2 through Step 9 for the remaining power supply.
11. Observe the LED on the power supply. The LED blinks green as it transitions online. If the power supply
is functioning normally, the LED lights green steadily.
If the LED is red or not lit, the power supply is not functioning normally. Repeat the cabling procedures.
