Chapter 2 Preparing for Installation Safety Guidelines Lifting Guidelines A fully configured router can weigh as much as 275 pounds (lb) (124.74 kilograms (kg)), while an empty chassis weighs 125 lb (56.7 kg). These systems are not intended to be moved frequently. Before you install the router, ensure that your site is properly prepared so you can avoid having to move the router later to accommodate power sources and network connections.
Chapter 2 Preparing for Installation Site Requirement Guidelines Site Requirement Guidelines The following sections contain the site requirement guidelines that you should be familiar with before installing the router: • Rack-Mounting Guidelines, page 2-6 • Air Flow Guidelines, page 2-12 • Temperature and Humidity Guidelines, page 2-13 • Power Connection Guidelines, page 2-13 • NEBS Supplemental Unit Bonding and Grounding Guidelines, page 2-18 • Site Wiring Guidelines, page 2-20 Rack-Mounting
Chapter 2 Preparing for Installation Site Requirement Guidelines Equipment Rack Types 27959 Figure 2-2 a b c Enclosed Rack Figure 2-2a shows a free-standing, enclosed rack with two mounting posts in the front. The router should not be installed in this type of enclosed rack, because the router requires an unobstructed flow of cooling air to maintain acceptable operating temperatures for its internal components.
Chapter 2 Preparing for Installation Site Requirement Guidelines Telco Rack Figure 2-2c shows a telco-type rack. The telco-type rack is an open frame consisting of two posts tied together by a cross-bar at the top and a floor stand at the bottom. This type of rack is usually secured to the floor and sometimes to an overhead structure or wall for additional stability. The router chassis can be installed in the telco-type rack either in a front-mounted position or a center-mounted position.
Chapter 2 Preparing for Installation Site Requirement Guidelines In the center-mounted position, you secure a set of optional center-mount brackets to the rack posts. The chassis rack-mounting flanges are then secured to the center-mount brackets (Figure 2-4). The center-mounted position moves the center of gravity of the chassis closer to the vertical axis of the rack posts, which adds to the stability of the rack installation.
Chapter 2 Preparing for Installation Site Requirement Guidelines Site Layout and Equipment Dimensions To help maintain trouble-free operation, adhere to the following precautions when planning your rack installation: • Ensure the site of the rack includes provisions for source AC or DC power, grounding, and network interface cables. • Allow sufficient space to work around the rack during the installation. You need: – At least 3 feet adjacent to the rack to move, align, and insert the chassis.
Chapter 2 Preparing for Installation Site Requirement Guidelines • To avoid noise interference in network interface cables, do not route them directly across or along power cables. Figure 2-5 shows the footprint and outer dimensions of the of the router chassis. Figure 2-5 Router Chassis Footprint and Dimensions—Top View 17.531 17.798 in. 25.533 in. 18.95 in. 149929 7.735 in.
Chapter 2 Preparing for Installation Site Requirement Guidelines Air Flow Guidelines Cool air is circulated through the router by the blower module located at the top of the chassis. The blower module maintains acceptable operating temperatures for the internal components by drawing in cool air through the air filter in front of the switch fabric and alarm card cage, and circulating the air through both card cages (Figure 2-6).
Chapter 2 Preparing for Installation Site Requirement Guidelines • Unrestricted air flow—Allow sufficient air flow by maintaining a minimum of 6 inches (15.24 cm) of clearance at both the inlet and exhaust openings on the chassis and the power modules. If the air flow is blocked or restricted, or if the inlet air is too warm, an overtemperature condition can occur within the router. Under extreme conditions, the environmental monitoring system powers off the router to protect the components.
Chapter 2 Preparing for Installation Site Requirement Guidelines AC-Powered Routers AC PEMs operate in the nominal range of 200 VAC to 240 VAC and require a minimum service of: • 20 A for operation in North America • 16 A for international operation • 13 A for operation in the UK Each of the AC power inputs requires separate dedicated branch circuit. For a list of the nominal and acceptable value ranges for source AC power, refer to Table A-2 on page A-3.
Chapter 2 Preparing for Installation Site Requirement Guidelines Table 2-1 lists power cord options. All AC-input power supply power cords measure 14 feet (4.3 m).
Chapter 2 Preparing for Installation Site Requirement Guidelines You must terminate DC power cables using cable lugs at the power shelf end.Ensure the lugs are dual-hole and that they fit over M6 terminal studs at 0.625-inch (15.88-mm) centers (for example, Panduit Part Number LCD8-14A-L or equivalent). Figure 2-8 shows the type of lug required for DC-input cable connections. Figure 2-8 DC Power Cable Lug All measurements in inches 2.24 End View 0.48 Ø 0.267 2 holes 0.08 0.63 0.
Chapter 2 Preparing for Installation Site Requirement Guidelines Figure 2-9 shows a typical source DC power distribution scheme for a 2800 W DC PDU.
Chapter 2 Preparing for Installation Site Requirement Guidelines The color coding of source DC power cable leads depends on the color coding of the site DC power source. Because there is no color code standard for source DC wiring, be sure that power source cables are connected to the PDU using the proper positive (+) and negative (–) polarity: Caution • In some cases, the source DC cable leads might have a positive (+) or a negative (–) label.

Chapter 2 Preparing for Installation Site Requirement Guidelines To ensure a satisfactory supplemental ground connection to the router, use the following parts: Note These parts are not available from Cisco, but are available from commercial vendors. • One grounding lug, which have two M6 bolt holes with 0.625 to 0.75-inch (15.86 to 19.05-mm) spacing between them, and a wire receptacle large enough to accept a 6-AWG or larger, multistrand copper wire.
Chapter 2 Preparing for Installation Site Requirement Guidelines Give special consideration to the effect of a lightning strike in your vicinity, especially if the wiring exceeds the recommended distances, or if it passes between buildings. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena can easily induce enough energy into unshielded conductors to destroy electronic devices.
Chapter 2 Preparing for Installation PRP Port Connection Guidelines PRP Port Connection Guidelines This section contains detailed cabling and signal information for all interface and port connections to the PRP. It also provides information for Ethernet routing and equipment. Caution Ports labeled Ethernet, 10BASE-T, Token Ring, Console, and AUX are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits.
Chapter 2 Preparing for Installation PRP Port Connection Guidelines Figure 2-11 shows the auxiliary and console port connections from the PRP to the associated devices.
Chapter 2 Preparing for Installation PRP Port Connection Guidelines PRP Auxiliary Port Signals The PRP auxiliary port is a DTE, RJ-45 interface for connecting a modem or other DCE device (such as a CSU/DSU or another router) to the PRP. The auxiliary port supports hardware flow control and modem control. Table 2-2 lists the signals used on the auxiliary port.
Chapter 2 Preparing for Installation PRP Port Connection Guidelines PRP Console Port Signals The PRP console port is a DCE RJ-45 interface for connecting a terminal to the router. The console port does not support modem control or hardware flow control and requires a straight-through RJ-45 cable. Before connecting a terminal to the console port, check the terminal setting for the data transmission rate, in bits per second (bps).
Chapter 2 Preparing for Installation PRP Port Connection Guidelines PRP Ethernet Connections The PRP has two RJ-45 MDI Ethernet ports; ETH0 and ETH1 (Figure 2-12). PRP Ethernet Connections TX EN TX PRIMARY 70693 PRIMARY LIN K EN SL RX RX ETH 1 S OT LOT -0 -1 ETH 0 LIN K Figure 2-12 These connections support IEEE 802.3 and IEEE 802.3u interfaces compliant with 10BASE-T and 100BASE-TX standards.
