| Prepare Your Installation Site |
You must perform three logistical steps when unpacking and installing your Cisco AccessPath-VS3 Packet Telephony Concentrator:
1. Unload the crate from its shipping vehicle.
2. Move the crate using a forklift or similar device to the unpacking site.
3. Move the unpacked system to the installation site.
Consider the following issues before you unpack and install your system:
Cisco's seismic safety guidelines include bolting patterns that conform to Network Equipment Building Standards (NEBS) requirements.
To ensure seismic safety, you must anchor the cabinet to the floor as follows:
1. Drill 4 holes.
2. Insert casings (anchors) in the holes.
3. Secure the system to the anchors using threaded rods.
There are 3 possible bolting patterns:

| Prepare Your Installation Site (continued) |
Cisco recommends the use of a bolting kit from HILTI, which has passed seismic testing when used with the Cisco AccessPath-VS3 system. If you use a bolting kit from another vendor (or if you supply your own), it is your responsibility to verify the fulfillment of seismic safety standards.
The recommended kit can be ordered by contacting HILTI, and includes the following elements:
In addition, you will use the load plate you saved when you unbolted the system from its shipping pallet.
Plan adequate human resources to unload and install the Cisco AccessPath-VS3 system. To safeguard both equipment and personnel during the installation process, Cisco recommends that five people be present whenever you move the cabinet.
A fully loaded system, with its casters installed for transport, can weigh up to 1300 lbs (590 kg), and moving it carelessly can endanger personnel.
Verify that you have the following tools available:
 | Warning Before installing the Cisco AccessPath-VS3 system, refer to the warnings listed in the document Regulatory Compliance and Safety Information for the Cisco AccessPath-VS3 Packet Telephony Concentrator. |

| Uncrate and Move the System (continued) |
Perform the following steps to remove the ramp and attach it to the shipping pallet:
Step 2 Lift one of the ramp legs away from the system and walk to the front of the system.
Step 3 Locate the 2 pins that extend from the shipping pallet. Align the ramp leg so that the hole at its end is directly over one of the pins, and lower it until the peg fits securely into the hole in the wood. The first of the 2 ramp legs is now locked into position.
Step 4 Repeat Step 2 and Step 3 with the second ramp leg.
Step 5 Check again that the pins are secure and locked.
The ramp is ready for use.

| Uncrate and Move the System (continued) |
Perform the following steps to unbolt the unit:
Step 2 Using a standard 7/8-inch wrench, loosen the nuts that secure the bolts to the cabinet. Remove the nuts and set them aside.
Step 3 Remove and save the 2 x 3 inch (5.1 x 7.6 cm) load plates that sit beneath the nuts. (You will use these for seismic safety bolting.)
Step 4 Push the loosened bolts through the pallet so they fall to the floor.
Step 5 Repeat Step 1 through Step 4 for the remaining three bolts.
Step 6 Make sure that all 4 bolts drop completely through the pallet to the floor and do not obstruct the system.

| Uncrate and Move the System (continued) |
Have one person work the front caster assembly and one person the back assembly. Now raise the system:
Step 2 Turn the wrench clockwise to lower the casters and raise the cabinet. Each turn of the wrench will lower the caster assembly and raise the Cisco AccessPath-VS3 system.
 | Caution
You must raise the entire assembly 1 1/2 inches (3.8 centimeters) (the maximum possible) to ensure that the cabinet clears the ramp. Otherwise, the cabinet might catch on the ramp lip. |
Step 3 Continue to lower the front and back casters in a coordinated fashion until all 4 wheels barely touch the pallet surface. Do not allow the wheels to touch the surface.
Step 4 Align the front and back caster wheels using your hands until they are parallel with each other and face the attached ramp legs. Be sure that no one is turning the caster assembly as you align the wheels.

| Uncrate and Move the System (continued) |
 | Warning We recommend that 4 people work together to roll the unit down the ramp and to the installation site. Using fewer than 3 people will substantially increase the risk to personnel and equipment. |
Step 5 Position yourself and the remaining personnel in the most efficient configuration. A fifth person should be present as a safety observer. If, as recommended, you have assigned 4 people to move the system, position each at a corner of the unit. If only 3 people are available, place 1 in front and 1 on each side.
Step 6 Roll the Cisco AccessPath-VS3 system down the ramp. Be sure to keep the unit under control, and move it as quickly as possible down the ramp.
| Uncrate and Move the System (continued) |
Step 7 After the system has reached the flat surface of the floor, roll it to the installation site. Check for any protrusions or obstacles that exist en route to the installation location. Walk quickly enough to maintain momentum, but not so quickly that you have difficulty turning or slowing the cabinet.
Step 8 After you have reached the installation site, move the cabinet into position over the bolt holes. See the "Install the Cabinet" section in Chapter 3 of the hardware installation guide.
| Install the System |
After moving the Cisco AccessPath-VS3 system to the installation site, you can install it by performing the following steps:
Step 2 If you have not yet placed the steel anchors into each hole, slide the cabinet away from the holes and do so now.
Step 3 Collect the 4 threaded rods that secure the system to the floor. Place them all within reach for easy access. (Each comes with a washer and a nut used to secure the rod within the casing. A load plate, also required to secure the rod, is shipped with the system packaging.)
Step 4 Locate the first mounting position on the base of the cabinet. Place the first thread loosely in the hole. Using a screwdriver, screw it down into the casing until it stops. Do not attempt to tighten the thread any further at this point.
Step 5 Repeat Step 4 for the remaining threaded rods.

To connect power to your system, you must first verify that your site meets the power requirements, which help guarantee power redundancy to the Router Shelf and the Switch Shelf:
For a Cisco AccessPath-VS3 system equipped for AC power, the power is supplied to the various shelves through a power strip located on the right side of the system, inside the front door.
Step 2 Verify that the AC power connections are firm between the shelves and the power strip. Check the connections in this order:
Step 3 Plug any unconnected power cords that come from the Cisco AccessPath-VS3 system into the power strip at the appropriate location.
Step 4 Connect each of the AC power input cables that bring power into the system power strip to a separate grounded power source. (This will require seven dedicated 20A (100-127 VAC) or 10A
(100-240 VAC) circuits per cabinet.)
Step 5 Turn each of the shelves ON, one at a time.

For a Cisco AccessPath-VS3 system equipped for DC power, the power is supplied to the various shelves through a DC busbar. This busbar comes with the system and is installed in the system cabinet.
Check DC grounding and busbar connections in the following order, starting at the top of the rack:
Step 2 If you need to connect any of the shelves to the DC busbar, do so:
Step 3 Connect the main earthing wire to either set of double grounding studs using a 2 to 6 AWG copper stranded wire crimped to a double lug of the appropriate size. (These studs are located at the top and bottom of the rear of the system.)
Step 4 Remove the DC busbar inlet panel. Connect DC power to the DC busbar. This will require 4 dedicated 45A (-48 to -60 VDC) circuits per Cisco AccessPath-VS3 system cabinet.
With the DC power source turned OFF, connect a 2 to 6 AWG copper-stranded wire to the DC busbar using the provided double lugs and following these guidelines:
