Maintaining the XRE200 Modules

 

Installing and Removing XRE200 External Routing Engine Hardware Components

The field-replaceable units (FRUs) in an XRE200 External Routing Engine are:

  • AC or DC power supplies

  • Fan modules

  • Hard Disk Drive (HDD) modules

  • Virtual Chassis Control Interface (VCCI) modules

The AC or DC power supply and fan modules are hot-removable and hot-insertable: You can remove and replace them without powering off the external Routing Engine or disrupting external Routing Engine functions.

A single HDD module is hot-removable and hot-insertable: You can remove and replace it without powering off the external Routing Engine or disrupting external Routing Engine functions.

Caution

Do not remove both HDD modules at the same time when the external Routing Engine is powered on. If you need to remove both HDD modules, power off the switch before removing the modules.

The VCCI module is not hot-removable or hot-insertable.

Caution

You must power off the external Routing Engine if you need to remove or insert a VCCI module.

See these topics for instructions for installing and removing components:

Removing a VCCI Module from an XRE200 External Routing Engine

XRE200 External Routing Engines have two Virtual Chassis Control Interface (VCCI) module slots on the front panel. The slots support 10/100/1000BASE-T RJ-45 and 1000BASE-X Gigabit Ethernet small form-factor pluggable (SFP) VCCI modules. The VCCI modules are offline field-replaceable units (FRUs). You can use this procedure for both types of VCCI modules.

Ensure that you have the following parts and tools available to remove a VCCI module:

  • Phillips (+) screwdriver, number 2

  • An antistatic bag or an antistatic mat

Caution

You must power off the external Routing Engine before you remove or insert a VCCI module.

To remove a VCCI module from an external Routing Engine (see Figure 1):

  1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  2. Power off the XRE200 Routing Engine. See Powering Off an XRE200 External Routing Engine.
  3. Unscrew both captive screws counterclockwise using your fingers. If you are unable to easily unscrew the captive screws with your fingers, use the screwdriver.
  4. Gently pull the VCCI module toward you and out of the VCCI module slot, being careful to keep one hand underneath the module to support it when it is removed from the chassis.
  5. Place the VCCI module in the antistatic bag or on the antistatic mat.

Installing a VCCI Module in an XRE200 External Routing Engine

XRE200 External Routing Engines have two Virtual Chassis Control Interface (VCCI) module slots on the front panel. The slots support 10/100/1000BASE-T RJ-45 and 1000BASE-X Gigabit Ethernet small form-factor pluggable (SFP) VCCI modules. You can use this installation procedure for both types of VCCI modules.

VCCI modules are offline field-replacable units (FRUs).

Ensure that you have the following parts and tools available to install a VCCI module:

  • A Phillips (+) screwdriver, number 2

Caution

You must power off the external Routing Engine before you remove or insert a VCCI module.

To install a VCCI module in an external Routing Engine (see Figure 2):

  1. Power off the XRE200 External Routing Engine. See Powering Off an XRE200 External Routing Engine.
  2. If the VCCI module slot has an installed VCCI module, remove the module. See Removing a VCCI Module from an XRE200 External Routing Engine.
  3. Taking care not to touch VCCI module components, pins, leads, or solder connections, remove the module from its bag.
  4. Ensure the VCCI module is properly aligned with the VCCI module slot. When the module faceplate is properly aligned, the port numbers on the face plate read 0 through 3 from left to right.
  5. Insert the VCCI module into the VCCI module slot, and gently push the module all the way into the slot until the module is seated flush in the slot.Caution

    Do not use too much force to get the VCCI module seated flush into the VCCI module slot. If backpressure is preventing the module from seating flush in the module slot, remove the module from the slot and retry the procedure, taking care to ensure the module is properly aligned with the module slot.

  6. Tighten both screws on the VCCI module using your fingers. If additional tightening is necessary, tighten the screws using the screwdriver.
  7. Repeat Step 2 through Step 6 if you need to install a second VCCI module.
  8. Power on the external Routing Engine. See Powering On an XRE200 External Routing Engine.

Removing an HDD Module from an XRE200 External Routing Engine

XRE200 External Routing Engines support up to two hard disk drive (HDD) modules on the front panel. The HDD modules are hot-insertable and hot-removable field-replaceable units (FRUs).

Ensure that you have the following parts and tools available to remove an HDD module:

  • Phillips (+) screwdriver, number 2

  • An antistatic bag or an antistatic mat

Caution

A single HDD module must be installed in a powered-on XRE200 External Routing Engine. Removing both HDD modules when the external Routing Engine is powered on can cause severe hardware issues.

To remove an HDD module from an external Routing Engine (see Figure 3):

  1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
  2. A powered-on XRE200 External Routing Engine always requires at least one operational HDD module. If the switch is powered on, perform this procedure only if an operational HDD module is working in the other HDD module slot. If you are removing the only operational HDD module, power off the external Routing Engine. See Powering Off an XRE200 External Routing Engine.

    Unscrew both captive screws counterclockwise using your fingers. If you are unable to unscrew the captive screws using your fingers, use the screwdriver.

  3. Gently pull the HDD module toward you and out of the HDD module slot, being careful to keep one hand underneath the module to support it when it is removed from the chassis.
  4. Place the HDD module in the antistatic bag or on the antistatic mat.

Installing an HDD Module in an XRE200 External Routing Engine

XRE200 External Routing Engines have two 160 GB hard disk drive (HDD) module slots on the front panel. HDD modules are hot-removable and hot-insertable field-replaceable units (FRUs).

Ensure that you have the following parts and tools available to install the HDD module:

  • A Phillips (+) screwdriver, number 2

Caution

A single HDD module must be installed in a powered-on XRE200 External Routing Engine. Removing both HDD modules when the external Routing Engine is powered on can cause severe hardware issues.

To install an HDD module in an external Routing Engine (see Figure 4):

  1. Taking care not to touch HDD module components, pins, leads, or solder connections, remove the new HDD module from its bag.
  2. If the switch is powered on, at least one HDD module must be installed. Perform this step only when an HDD module is installed in the other HDD module slot or when the external Routing Engine is powered off.

    If you need to remove an HDD module in the HDD module slot, remove the HDD module. See Removing an HDD Module from an XRE200 External Routing Engine.

  3. Ensure the HDD module is properly aligned with the HDD module slot. The HDD module faceplate should be aligned so that the screws are aligned with the top of the HDD module slot.
  4. Insert the HDD module into the HDD module slot, and gently push the module all the way into the slot until the module is seated flush in the slot.Caution

    Do not use too much force to get the HDD module seated flush into the HDD module slot. If backpressure is preventing the HDD module from seating flush in the HDD module slot, remove the HDD module from the slot and retry the procedure, taking care to ensure the HDD module is properly aligned with the HDD module slot.

  5. Tighten both screws on the HDD module using your fingers. If additional tightening is necessary, tighten the screws using the screwdriver.
