Washers are required

Mounting the Chassis on a Rack

To mount the chassis on a rack:

Before you begin

Your chassis ships with a pair of brackets and mounting screws for use with a 19-inch rack. For information about the mounting screws that you must use, see Mounting Screws.


Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

  • If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006

  • The unit should be mounted at the bottom of the rack if it is the only unit in the rack.

  • When mounting the unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.


Warning

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024


Warning

Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018


Warning

To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of: 40 °C (104 °F). Statement 1047


Caution

If installed on enclosed racks, the racks must have adequate ventilation. An enclosed rack should never be overcrowded and should have louvers and a fan.

If the Cisco VG310 or Cisco VG320 is installed in an enclosed rack with a ventilation fan at the top, make sure that heated air drawn upward from other equipment does not pass through the Cisco VG310 or Cisco VG320 chassis.

If the chassis is installed using slide rails, check for blocked ventilation ports when it is in position in the rack or cabinet. Make sure that the ventilation ports of the chassis are not blocked.

Tip

Baffles can help isolate exhaust air from intake air. Baffles also help draw cooling air through the cabinet. The best location for the baffles depends on the airflow patterns in the rack. You can test the airflow by experimenting with different equipment arrangements.


Note

Machine screws for securing the chassis in a rack are not included in the package. You must arrange for machine screws of the appropriate size required by your rack.

This section describes how to remove and replace a CompactFlash memory card in Cisco VG310 and Cisco VG320:

Removing a CompactFlash Memory Card


Caution

Do not remove a CompactFlash memory card from the chassis while it is being accessed. This can cause data corruption and erratic operation. The CompactFlash memory card LED blinks to indicate when flash memory is being accessed. Removing the CompactFlash memory card from the chassis while flash memory is being accessed can cause data corruption and erratic operation.

Procedure

Step 1

Read the Safety Recommendations and disconnect the power supply before you replace any module.

Step 2

Press the ejector button next to the CompactFlash memory card. The ejector button moves outward so that it projects from the panel.

Step 3

Press the ejector button again to eject the CompactFlash memory card partially out of its slot.

Step 4

Pull the memory card out of its slot.

Step 5
