One port provides direct CLI access from a console terminal; the other Auxiliary port provides debug access from a console terminal. The management port is considered a data terminal equipment interface (DTE). Direct connection to a terminal or PC (which also have DTE interfaces) requires a crossover cable. See "Accessing E Series Routers" on page 61 for more information about management access. Connecting to the Network To connect the router to the network: 1. 2. Insert an Ethernet cable (RJ-45) connector into the 10/100Base-T (RJ-45) port on the SRP IOA until it clicks into place. Connect the other end of the cable to the appropriate Ethernet network for an out-of-band connection. Connecting to a Console Terminal When you connect a console directly to the SRP IOA, use a cable appropriate for your terminal connector. The cable must have a female DB-9 connector to attach to the RS-232 port on the SRP IOA. To connect the console to the SRP IOA: 1. Insert the female DB-9 connector into the RS-232 port, and tighten the screws. CAUTION: Do not overtighten the screws. 2. Connect the other end of the cable to your terminal's serial port (VT100/ANSI). Cabling IOAs This section describes the common connector types used with IOAs. Cabling IOAs 51 E120 and E320 11. 1. x Hardware Guide LC Duplex Connectors In accordance with EN60825-1, Safety of Laser Products - Part 1: Equipment Class, Requirements, and User's Guide (2001), multimode IOAs with LC connectors are defined as follows: CLASS 1 LED PRODUCT. In accordance with EN60825-1, Safety of Laser Products - Part 1: Equipment Class, Requirements, and User's Guide (2001), single-mode IOAs with LC connectors are defined as follows: CLASS 1 LASER PRODUCT. WARNING: Do not look directly into LC-style fiber connectors. The fiber-optic laser used in single-mode fiber (SMF) meets the regulatory requirements for casual exposure to the eye; however, looking directly into a laser can cause eye damage. WARNING: EN60825-1, Class 1 laser fiber connectors are for connection only to Class 1 laser devices. SFPs See "IOAs Requiring SFPs" on page 35 and the E120 and E320 Module Guide for information on small form-factor pluggable transceivers (SFPs) used on IOAs. Cabling the Router for Power After you have correctly cabled the SRP IOA, you must attach grounding and electrical wires before you attempt system power-up. Three main tasks are involved: 1. Switch all router power switches to OFF. CAUTION: Switches may have inadvertently flipped to ON during shipping and installation. Connect the grounding wires to the chassis. 2. WARNING: Always connect the grounding wires first (before connecting the power cables) and disconnect them last when installing or servicing the router. 52 Cabling the Router for Power Chapter 5: Cabling the Router 3. Connect the power cables to the PDUs. See "System Specifications" on page 91 for the power requirements for the router. Table 8 on page 53 identifies the cabling requirements. Table 8: E320 Router PDU Cables and Wires Needed Cable/Wire One 6-AWG ground wire Two 4-AWG wire leads Two 4-AWG wire leads From PDU ground terminal PDU Power A ­48 VDC and RTN leads PDU Power B ­48 VDC and RTN leads To Termination ground Appropriate leads on power source No. 1 Appropriate leads on power source No. 2 Figure 27 on page 54 shows the main components of a PDU. Cabling the Router for Power 53 E120 and E320 11. 1. x Hardware Guide Figure 27: PDU Task 1: Turn Off All Router Power Before starting to cable the router, push all router power switches to OFF to turn off the router. Task 2: Connect the Grounding Cables The router has two grounding studs located in the rear of the chassis, near the power inputs. 2. Locate the grounding studs on the router (Figure 27 on page 54). Remove the nuts and locking washers from the grounding studs. 54 Cabling the Router for Power Chapter 5: Cabling the Router NOTE: We recommend a minimum of 6-AWG ground wire with a ring-style terminal. Place the grounding cable lead on one of the grounding studs and tighten the nuts to secure the connection. Connect the other end of the ground cable to the appropriate ground termination lead. 5. NOTE: When grounding the router, leave a service loop in the grounding cable to ensure that the grounding cable is the last cable to disconnect from the shelf if strain is placed on the electrical cables. Task 3: Connect the Power Cables To connect power cables to the router, follow these steps. See Figure 27 on page 54 as needed. NOTE: Juniper Networks has qualified an AC power supply unit for use with the router. Contact your account representative for more information. WARNING: Before you begin this procedure, be sure the power source is turned off, the router is turned off, and proper grounding wires are attached. Be sure you have completed "Task 1: Turn Off All Router Power" on page 54 and "Task 2: Connect the Grounding Cables" on page 54. If applicable, loosen the screws from the clear power input module cover and remove it. 1. [. . . ] See Table 19 on page 111 for the pinout of the Ethernet port.
