4 Installing removable components

The figures of router and components in this document are for illustration only.

Slot arrangement

"LPU" in Figure4-1 refers to an interface module, "SFU" refers to a single-chassis fabric module, "MSFU" refers to a multi-chassis fabric module, and "PEM" refers to a power tray.

Figure4-1 Slot arrangement

 

Installing MPUs

CAUTION: ·     The router supports active/standby MPU switchover when you install two MPUs for the router. For the standby MPU to start up correctly, make sure the active and standby MPUs are the same model. ·     When you install an MPU, avoid damaging the connectors on the MPU. ·     To prevent a filler panel from being drawn into the chassis when fan speed is high, use both hands to grasp the filler panel by its two sides during filler panel installation and removal on an operating router. ·     If you are not to install an MPU in an MPU slot, keep the filler panel in the slot.

 

The router has two MPU slots. You can install one MPU, or two MPUs in 1+1 redundancy for the router.

To install an MPU:

1.     Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

2.     Remove the filler panel from the target MPU slot.

Keep the removed filler panel secure for future use.

Figure4-2 Removing a filler panel

 

3.     Orient the MPU correctly and align the MPU with the slot. Insert the MPU into the slot and fully open the ejector levers on the MPU.

4.     Continue to push the MPU by its middle part on the front panel until the brakes on its ejector levers touch the slot edges tightly.

5.     Close the ejector levers until they come in close contact with the front panel.

6.     Use a Phillips screwdriver to fasten the captive screws on the MPU.

Installing fabric modules

CAUTION: ·     The router provides eight fabric module slots at the rear. To use the following interface modules, install the fabric modules in slots 22 to 27. Installing fabric modules in slots 28 and 29 will not improve interface module performance. ¡     CR-19K-LPU-2002 ¡     CR-19K-LPU-2002B ¡     CR-19K-LPU-4004 ¡     CR-19K-LPU-8004 ¡     CR-19K-LPU-CC04 ¡     CR-19K-LPU-CC04B ¡     CR-19K-LPU-CC08 ¡     CR-19K-LPU-CQ06B ¡     CR-19K-LPU-CQ12 ¡     CR-19K-LPU-CQ12B ¡     CR-19K-LPU-CQ18 ¡     CR-19K-LPU-SP ¡     CR-19K-LPU-XP20CC02 ¡     CR-19K-LPU-XP40 ¡     CR-19K-LPU-XP48 ¡     CR-19K-LPU-XP72 ·     When you install a fabric module, avoid touching the connectors on the fabric module. ·     To prevent a filler panel from being drawn into the chassis when fan speed is high, use both hands to grasp the filler panel by its two sides during filler panel installation and removal on an operating router. ·     If you are not to install a fabric module in a fabric module slot, keep the filler panel in the slot.

 

To install a fabric module:

1.     Wear an ESD wrist strap and make sure it make good skin contact and is reliably grounded.

2.     Remove the filler panel from the target fabric module slot.

Keep the removed filler panel secure for future use.

3.     (Optional.) For a multi-chassis fabric module, remove the protection cover from the front panel, as shown in Figure4-4.

Figure4-4 Removing the protection cover

 

4.     Correctly orient the fabric module and align the fabric module with the slot. Insert the fabric module steadily into the slot and fully open the ejector levers of the fabric module, as shown in Figure4-5.

Figure4-5 Installing a fabric module

 

5.     Continue to push the fabric module by its middle part on the front panel until the brakes on its ejector levers touch the slot edges tightly.

6.     Close the ejector levers until they come in close contact with the front panel.

7.     Use a Phillips screwdriver to fasten the captive screws on the fabric module.

Installing interface modules

	CAUTION: ·     If you are not to install an interface module in an interface module slot, keep the filler panel in the slot. ·     To prevent a filler panel from being drawn into the chassis when fan speed is high, use both hands to grasp the filler panel by its two sides during filler panel installation and removal on an operating router.

 

Installing an interface module that uses detachable ejector levers

	CAUTION: ·     Put the detachable ejector lever back on its holder after use and then attach it to the chassis or cabinet for future use. ·     The ejector lever holder is magnetic. Be aware of electromagnetic interference. ·     Do not use only one detachable ejector lever to install or remove an interface module. ·     Do not hold detachable ejector levers to lift an interface module.

 

Figure4-6 Detachable ejector lever

 

To install an interface module that uses detachable ejector levers:

1.     Wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is reliably grounded.

2.     Remove the filler panel from the target interface module slot.

Keep the removed filler panel secure for future use.

3.     Remove the protection box (if any) from the connector side of the interface module, as shown in Figure4-7.

Keep the removed protection box secure for future use.

The number of screws for securing the protection box in Figure4-7 is for illustration only and the actual number of screws on your interface module might differ from that.

4.     Correctly orient the interface module. Align the module with the slot and push it steadily into the slot along the guide rails until about half of the module is in the slot.

Figure4-8 Installing an interface module that uses detachable ejector levers

 

5.     Attach the ejector lever holders to the chassis or cabinet and then remove the ejector levers from the holders.

6.     Identify the L and R marks on the ejector levers and attach them to left and right ejector lever retainers of the interface module, with the lettering on the ejector levers facing upward.

Figure4-9 Installing an ejector lever

 

7.     Open the ejector levers and continue to push the module by its middle part on the front panel until you cannot push it any further.

8.     As shown in Figure4-10, close the ejector levers until they come in close contact with the front panel. Use a Phillips screwdriver to fasten the captive screws on the interface module.

9.     As shown in Figure4-11, press the spring tab on each ejector lever retainer to remove the ejector levers. Place the ejector lever back on their holders and keep them secure for future use.

Figure4-11 Removing an ejector lever

 

Installing an interface module that uses general ejector levers

1.     Wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is reliably grounded.

2.     Remove the filler panel from the target interface module slot.

Keep the removed filler panel secure for future use.

3.     Open the ejector levers of the interface module. Gently push the interface module into the slot along the guide rails.

4.     Continue to push the interface module by its middle part on the front panel until you cannot push it any further. Then close the ejector levers.

5.     Use a Phillips screwdriver to fasten the captive screws on the interface module.

6.     Pivot up the ejector levers on the interface module.

Installing interface subcards

	CAUTION: ·     If you are not to install an interface subcard in a slot on an interface module, keep the filler panel in the slot. ·     To prevent a filler panel from being drawn into the chassis when fan speed is high, use both hands to grasp the filler panel by its two sides during filler panel installation and removal on an operating router.

 

For the interface subcard compatibility with interface modules, see H3C CR19000-20 Core Router Hardware Information and Specifications.

To install an interface subcard:

1.     Wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is reliably grounded.

2.     Remove the filler panel from the target slot on the interface module.

Keep the removed filler panel secure for future use.

3.     Correctly orient the interface subcard and open the right ejector lever of the interface subcard.

4.     Insert the interface subcard into the slot and push it steadily into the slot along slide rails.

5.     Continue to push the interface subcard by its middle part on the front panel until you cannot push it any further.

6.     Close the right ejector lever until it comes in close contact with the front panel.

7.     Use a screwdriver to fasten the captive screw on the interface subcard.
