Prepare for Installation
This chapter describes the equipment and site requirements required to prepare your site for installing a Cisco AccessPath-VS3.
The chapter contains the following sections:
Before installing your Cisco AccessPath-VS3, consider:
- Power and cabling requirements
- Equipment required to install the system
- Environmental conditions that your installation site must meet to maintain normal system operation.
Consider the following issues when you plan your installation site for the Cisco AccessPath-VS3:
- The unpacking and installation process consists of 3 steps:
- Unload the unit from the vehicle in which it is shipped.
- Use a forklift or similar device to move the unit to an unpacking site.
- Move the unpacked unit to the installation site.
- Choose a place to unload that has enough area to maneuver the cabinet—You must allow for the shipping crate, pallet, and 2-legged ramp, which exceeds 6 ft (1.83 m) long.
 | Caution
The ramp only attaches on 1 end of the pallet See the instructions on the side of the cardboard to correctly align the system before setting it down for unpacking. |
- Choose an installation site that can accommodate your Cisco AccessPath-VS3. Plan enough space for installing the High-End Extended configuration—Allow space for:
- Make sure you have enough people to help you safely unload and install the system (at least 4 are required, and it is good practice to have a fifth person to guide the other 4). The system is very bulky and heavy—A cabinet can weigh up to 1300 lb (590 kg), and moving it incorrectly can present dangers to both personnel and cabinet.
 | Warning
In order to safeguard both equipment and personnel during the installation process, Cisco recommends that 4 people participate in moving the unit. Using adequate manpower is the best guarantee that you will avoid harming people or equipment. |
To prepare your site for installation of the Cisco AccessPath-VS3, you must drill seismic safety holes that will receive bolts that anchor the system in the floor. Do these steps to drill the seismic safety holes:
Step 1 Choose 1 seismic safety pattern from the 3 provided in Figure 2-1.
Step 2 Measure and drill the holes. The holes must be at least 4.33 in. (110 mm) deep.
Note In the High-End Extended configuration, which is housed inside 2 Cisco AccessPath-VS3 cabinets, the maximum space between the 2 cabinets is 30 ft (9.14 m).
Step 3 Install the anchors (casings) which will receive the threaded rods that secure the system to the floor. See Chapter 3, "Install and Configure the Cisco AccessPath-VS3 Packet Telephony Concentrator," for detailed instructions on securing the system to the floor.
Cisco recommends the use of a bolting kit from HILTI. This kit has passed seismic testing when used with the Cisco AccessPath-VS3. If you use a bolting kit from another vendor (or if you supply one), it is your responsibility to confirm that it meets seismic safety standards.
The recommended kit, which you can order from HILTI, includes:
You will use also need the load plate that you removed when you unbolted the system from the pallet.
Cisco provides for Network Equipment Building Standards (NEBS) patterns and its own recommended pattern. Figure 2-1 shows the various seismic safety bolting patterns available. The Cisco-recommended drilling pattern is based on the 4 filled holes shown in Figure 2-1. Unlike the NEBS patterns, usage of the Cisco-recommended pattern does not require removal of any part of the equipment infrastructure.
Figure 2-1: Seismic Safety Bolting Patterns for the Cisco AccessPath-VS3
Note If you apply NEBS drilling patterns, then you must remove the Catalyst 5002 switch before you bolt your system down. Refer to the Cisco AccessPath Model 531 Hardware Upgrade and Configuration Guide for more information on removing and installing the Catalyst 5002 switch.
The following guidelines lower the workers' risk of injury and protect the equipment.
- The installation of your Cisco AccessPath-VS3 should be in compliance with national and local electrical codes. In the United States, the relevant code is National Fire Protection Association (NFPA) 70, United States National Electrical Code. In Canada, it is Canadian Electrical Code, part I, CC22.1. In other countries, you must observe the standards of the International Electrotechnical Commission (IEC) 364, part 1 through part 7.
- Review the safety warnings listed in the publication Regulatory Compliance and Safety Information for the Cisco AccessPath Model 531 before installing, configuring, troubleshooting, or maintaining the Cisco AccessPath-VS3.
- Always turn OFF that device's power supplies and unplug its power cables before opening, installing, or removing a Cisco AccessPath-VS3 device.
- Keep the installation area clear and dust free during and after installation.
- Use the Cisco AccessPath-VS3 in accordance with its marked electrical ratings and product usage instructions.
- Never attempt to lift an object that might be too heavy for 1 person to lift alone. If you are not sure how much a particular object or device weighs, refer to the appropriate device specifications listed in the tables in Chapter 1, "Product Overview."
- Do not wear loose clothing, jewelry (including rings and chains), or other items that might become trapped in the cabinet. Fasten your tie or scarf and roll up your sleeves.
- Keep tools and devices away from walk areas.
A fully configured Cisco AccessPath-VS3, with casters installed for transport, weighs approximately 1300 lb (590 kg). The cabinet is not intended to be moved frequently.
Before you install the system, make sure that your installation site is properly prepared so that it won't become necessary for you to move the system.
Whenever you move the Cisco AccessPath-VS3, follow these guidelines:
- Always disconnect all external cables before moving the Cisco AccessPath-VS3.
- Do not attempt to move the unit with less than 3 people.
- Make sure that your footing is solid throughout the path that you will move the cabinet on.
- Move the system slowly but steadily.
- Keep your back straight and push with your legs, not your back. If you must bend down to move the cabinet, bend at the knees and not at the waist to reduce the strain on your lower back muscles.
The port adapters and power supplies in the Router shelves are designed to be removed and replaced while the Cisco AccessPath-VS3 is operating without presenting an electrical hazard or damage, with the following exceptions:
- Power down the Switch shelf before removing its I/O controller and network processing engine,
- Power down any VoIP Access Server shelves before replacing their port adapters or power supplies.
Follow these basic guidelines while working with any electrical equipment.
In addition, use the following guidelines if working with any equipment that is disconnected from a power source, but still connected to telephone wiring or other network cabling:
| Warning
|
The network processing engine, I/O controller, and each port adapter consists of a printed circuit board that is fixed in a metal carrier that has connectors and a handle. If you are not familiar with the terms "ESD" read the following description:
Although the carrier helps protect the boards, use an antistatic strap whenever handling the network processing engine, I/O controller or port adapters.
Follow these guidelines to prevent ESD damage:
The environmental monitoring capability in the Cisco AccessPath-VS3 protects it and its components from potential overvoltage and overheating damage. After installation, the site must maintain an ambient temperature of 32 to 104ºF (0 to 40ºC), as dust-free as is practical.
The following sections list the site environment requirements for the Cisco AccessPath-VS3.
Note Plan your site configuration and prepare your site before installation. This assures normal operation and avoids unnecessary maintenance.
The AC-input power supplies operate on input voltage and frequency of 100 to 240 VAC and 50/60 Hz. Each AC-input power supply operating at 120 VAC requires 5A service.
Note Cisco recommends powering the Cisco AccessPath-VS3 from a 20A (100 to 127 VAC) or 15A (200 to 240 VAC) uninterruptible power source.
The DC-input power supply allows the Cisco AccessPath-VS3 shelves to operate at -48 VDC nominal in North America and -60 VDC in the European Community.
For system and device power specifications, including input voltage and operating frequency ranges, refer to the appropriate specification tables in Chapter 1, "Product Overview."
The following section gives guidelines for setting up the plant wiring and cabling at your site. When you plan the location of the new system, consider the distance limitations for signaling, EMI, and connector compatibility.
When wires are run for any significant distance in an electromagnetic field, field interference can distort the signals on the wires. The potential presence of interference has 2 implications for the construction of plant wiring:
Follow these guidelines to reduce the possibility of extraneous interference and damage from EMI pulses:
Note To predict and remedy strong EMI, you might also need to consult experts in radio frequency interference (RFI).
The size of your networks and the distances between connections depend on the type of signal, the signal speed, and the transmission media (the type of cabling used to transmit signals). For example, standard coaxial cable has a greater channel capacity than twisted-pair cabling and can transmit signals more clearly for a greater distance.
The distance and rate limits in the following descriptions are the IEEE (Institute of Electrical and Electronics Engineers) recommended maximum speeds and distances for signaling.
Note If you understand the electrical problems that might arise and can compensate for them, you can obtain good results with rates and distances greater than those listed here. For example, the recommended maximum rate for V.35 is 2 Mbps. Still, it is commonly used at 4 Mbps without any problems. You exceed the recommended limits at your own risk—Cisco recommends that you do not exceed specified transmission rate and distance limits.
When you prepare to connect your the Cisco AccessPath-VS3 to its network, there are interface-dependent factors that you must consider:
- Cable required (fiber, thick, or thin coaxial, shielded twisted-pair [STP] or unshielded twisted-pair [UTP] cabling)
- Distance limitations for each signal type
- Specific cables you need to connect each interface
- Any additional interface equipment you need, such as transceivers, hubs, switches, modems, channel service units (CSUs), or data service units (DSUs)
- Optional—If you build your own cables, see Appendix B, "Cabling Specifications" in the Cisco AccessPath Model 531 Hardware Upgrade and Configuration Guide.
For ordering information about any additional special equipment, contact a Cisco customer service representative. Remember that the Cisco AccessPath-VS3 is preconfigured in the configuration that you ordered. All devices, cables, documentation and miscellaneous parts should be included with the system.
In the Cisco AccessPath-VS3, field replaceable units (FRUs) are accessible from the front of the system. This means that all installation and removal procedures (with the exception of router shelf power cables) are performed at the front of the unit.
| Caution
Do not substitute a third-party vendor's rack mounting system for the 1 provided with the Cisco AccessPath-VS3. Cisco has designed the cabinet, including the cabling connections, specifically for your Cisco AccessPath-VS3. |
When you plan your rack installation, consider the following guidelines:
Additionally, read the precautions for avoiding overheating in the following portion of this section.
This section lists the operating and nonoperating environmental site requirements. The following ranges are those within which the Cisco AccessPath-VS3 can operate. A problem can also arise if your system operating conditions stay at either extreme repeatedly or for a prolonged period. You can lengthen system life by anticipating and correcting environmental anomalies before they approach a maximum operating range.

Planning a proper location for the Cisco AccessPath-VS3 is essential for successful operation. Equipment can overheat if it is placed too close together or lacks adequate ventilation. Additionally, device panels made inaccessible by poor equipment placement can make system maintenance difficult.
Follow these general precautions when you plan your equipment locations and connections:
Observe these precautions when you plan power connections to your Cisco AccessPath-VS3:
- Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power. Install a power conditioner if necessary.
- Install proper grounding to avoid damage from lightning and power surges.
Your Cisco AccessPath-VS3 has been fully configured at the factory; no assembly is required. However, you need the following tools and equipment to install the Cisco AccessPath-VS3:
