Installing the router

This section describes the procedure for installing the router.

 

	NOTE: ·     The chassis and component views in this section are for illustration only. ·     Keep the packages of the router and components for future use.

 

Confirming installation preparations

Before you install the router, verify that:

·     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 if you are to install the router in a rack. For how to install a rack, see the rack installation guide.

·     The rack is sturdy and is reliably grounded.

·     No debris or obstacles exist inside or around the rack.

·     Make sure the rack has enough space to accommodate the router. As a best practice to maintain the rack stability, install the router at the rack bottom. To mount multiple devices in a rack, install the heavier devices at the bottom.

·     The total height of the devices to be installed is no higher than the available installation height of the rack and enough clearance is reserved for cable routing.

·     The router is ready for installation and has been carried to a place near the rack and convenient for moving.

Attaching slide rails and cage nuts to the rack

Installing slide rails

Before you mount the router in a rack, install slide rails on the rack. As a best practice, purchase slide rails from H3C. For the slide rails recommended for the router, see H3C CR16000-F Router Series Hardware Information and Specifications. For information about installing the slide rails, see the installation guide shipped with the slide rails.

If the rack has slide rails installed, skip this section.

 

	IMPORTANT: To rack-mount the CR16018-F router and CR16018-FA router, reserve a 2 RU space between the router (including slide rails) and the rack bottom.

 

Installing cage nuts

Before mounting the chassis in the rack, attach cage nuts to the front rack posts.

1.     Align the bottom edge of a mounting bracket with the top flange of a slide rail. Then mark the cage nut installation holes on the front rack post.

If the mounting brackets are already installed, you can use a pattern tool to record the installation holes of the mounting brackets and mark the cage nut holes accordingly.

2.     Install cage nuts into the marked square holes on the front rack posts.

Installing cable management brackets and mounting brackets (for the CR16014-F router)

Before installing the CR16014-F router in the rack, install the cable management brackets and mounting brackets shipped with the router. The cable management brackets and mounting brackets for other models have been installed when shipped. Cable management brackets are used for cabling the router, and mounting brackets are used for attaching the chassis to the rack.

Installing cable management brackets

Cable management brackets include signal cable management brackets and power cord management brackets.

The CR16014-F router comes with the signal cable management brackets attached to the mounting brackets. You need to install the power cord management bracket for the router.

To install the power cord management bracket:

1.     Unpack the power cord management bracket.

2.     Place the power cord management bracket against the chassis and align the mounting holes in the bracket with the installation holes in the chassis.

3.     Use screws to secure the power cord management bracket to the chassis.

Figure 2 Installing a power cord management bracket

 

Installing mounting brackets

Before installing the router in the rack, attach the mounting brackets to the chassis.

The left and right mounting brackets available for the router are labeled with L and R marks, respectively.

To install the mounting brackets, face the front of the router, and attach the left and right mounting brackets to the two sides of the router, as shown in Figure 3.

Figure 3 Installing the mounting brackets

 

(Optional) Installing an air filter

Air filters are optional components and include chassis air filters and cabinet air filters. The applicable air filters vary by router model.

Air filter is an optional component for the router. If you have ordered an air filter, install it before mounting the router in the rack.

·     CR16010-F—Use a chassis air filter, which is installed over the air inlet vents at the bottom front of the chassis. Before installing an air filter, install the power cord management bracket for the chassis.

·     CR16010H-F/CR16010H-FA/CR16018-F/CR16018-FA—Use a cabinet air filter, which is attached to the interior side of the cabinet door.

·     Other models—Use a chassis air filter, which is installed at the left of the chassis.

Installing an air filter for a CR16010-F router

1.     Place the air filter over the inlet vents at the front panel bottom, and then align the captive screws on the air filter with the screw holes in the chassis.

2.     Faster the captive screws.

Figure 4 Installing an air filter

 

Installing an air filter for the CR16010H-F/CR16010H-FA/CR16018-F/CR16018-FA/CR16005E-F/CR16010E-F

To prevent dust for the CR16010H-F/CR16010H-FA/CR16018-F/CR16018-FA/CR16005E-F/CR16010E-F router, install an air filter on the cabinet. For a cabinet with a double-leaf door, cut the air filter into two halves based on the door size and install the air filter on the two door leaves.

To install an air filter on a cabinet:

1.     As shown in Figure 5, paste air filter securing strips along the edge of the interior side of the cabinet door at a location 1 to 2 cm (0.39 to 0.79 in) away from the perforation holes. For a large-area single-leaf door, attach more securing strips.

Mounting the router in the rack

WARNING! ·     Do not hold the handle of a fan tray or power module, air vents, or the handle on the real panel to move the router. Doing so might cause equipment damage or even bodily injury. ·     The router is heavy. As a best practice, use a mechanical lift to move it. ·     After placing the router on the slide rails, do not leave go of your hands immediately because this might tip the router, damaging the router or even causing bodily injury.

 

This task requires a minimum of two people.

To mount the router in the rack:

1.     Move the chassis to face the rear of the chassis towards the front of the rack.

2.     Lift the router by using the handles or supporting the bottom of the chassis until the bottom of the router is a little higher than the slide rails on the rack.

3.     Place the router on the slide rails and slide the router along the slide rails until the mounting brackets on the router touch the front rack posts.

4.     Attach the chassis to the rack with mounting screws.

Figure 9 Installing the chassis in the rack

 

If the mounting holes in the mounting brackets cannot align with the cage nuts on the rack, verify 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 router

	CAUTION: Before you use the router, connect the grounding cable correctly to guarantee lightning protection and anti-interference of the router.

 

Grounding the router with a grounding strip

	CAUTION: ·     Use the supplied grounding cable (yellow-green grounding cable). ·     Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire main or lightning rod.

 

If 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 router is compliant with the NEBS standards.

2.     Remove the grounding screws from the grounding holes at the rear of the chassis.

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 ring 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.
