Unpack the Device
Do not unpack the device until you are ready to install it. If the final installation site will not be ready for
some time, keep the chassis in its shipping container to prevent accidental damage. When you are ready to
install the chassis, proceed with unpacking it.
The chassis, accessory kit, publications, and any optional equipment you ordered may be shipped in more
than one container. When you unpack the containers, check the packing list to ensure that you received all of
the items on the list.
If anything appears damaged, or if you encounter problems when installing or configuring your system, contact
a customer service representative.
Mounting the Voice Gateway in Rack
You can install the Cisco VG420 Voice Gateway in 19-inch (48.26-cm) EIA and 23-inch (58.42-cm)
Southwestern Bell Corporation (SBC) racks. You can also mount the voice gateway in a 600-mm ETSI rack.
Use the standard brackets shipped with the hardware for mounting the chassis in a 19-inch EIA rack; you can
order optional larger brackets for mounting the chassis in a 23-inch SBC rack.
You can mount the voice gateway in the following ways:
• Center-front mounting: Brackets attached in the center front of the chassis with only the front panel
facing forward.
• Center-back mounting: Brackets attached in the center back of the chassis with only the back panel facing
forward.
• Front mounting: Brackets attached at the front of the chassis with the front panel facing forward.
• Back mounting: Brackets attached at the back of the chassis with the back panel facing forward.
Perform the following steps to mount the device on the rack:
Step 1
Attach the mounting brackets to the chassis as shown in the following images, using the screws provided.
Do not over-torque the screws. The recommended torque is 15 to 18 inch-lb (1.7 to 2.0 N-m).
