T1600 Routing Node Overview

The T1600 Internet routing node is a complete routing system that provides Gigabit Ethernet, SONET/SDH, and other high-speed interfaces for large networks and network applications, such as those supported by Internet service providers (ISPs). The routing node accommodates up to eight Flexible PIC Concentrators (FPCs), which can each be configured with a variety of network media types. The T1600 routing node provides up to 800 gigabits per second (Gbps), full duplex (1600 Gbps of any-to-any, non-blocking, half-duplex switching).
The routing node architecture cleanly separates control operations from packet forwarding operations. This design eliminates processing and traffic bottlenecks, permitting the routing node to achieve high performance.
■ Control operations in the routing node are performed by the host subsystem,
which runs JUNOS Internet software to handle routing protocols, traffic engineering, policy, policing, monitoring, and configuration management.
■ Forwarding operations in the routing node are performed by the Packet
Forwarding Engines, which consist of hardware, including ASICs, designed by Juniper Networks. Application-specific integrated circuits (ASICs) are a definitive part of the routing node design; these ASICs enable the routing node to achieve data forwarding rates that match current fiber-optic capacity. The T1600 routing node provides up to a total of 1600 million packets per second (Mpps) of forwarding.

T1600 Upgrade Kit

T1600 Upgrade Kit
To upgrade a T640 routing node to a T1600 routing node, you install the following hardware components:
■ Two redundant, load-sharing, three-input 240-A power supplies that connect to
the rear of the midplane
■ Five T1600-SIBs
■ One T1600 craft interface panel
You can order these components individually or order a T1600 upgrade kit that contains all the components. You must supply four additional DC power cables.
T1600 Upgrade Kit ■ 5
T1600 Routing Node Upgrade Guide
NOTE: These components must be installed before you can install a T1600-FPC in the T1600 routing node.

Power Supplies

Two redundant, load-sharing DC power supplies are located at the lower rear of the chassis in slots PEM0 and PEM1 (top to bottom). For power specifications for the system, power supplies, and power cables, see “T1600 Routing Node DC Power Specifications” on page 44.

Three-Input 240-A Power Supplies

Each three-input 240-A power supply weighs approximately 25 lb. (11.3 kg) and consists of three inputs, three 80-A circuit breakers, a fan, and LEDs to monitor the status of the power supply. Figure 3 on page 6 shows the three-input 240-A power supply.
Figure 3: Three-Input 240-A Power Supply
Three-Input 240-A Power Supply Inputs
The three-input 240-A DC power supply inputs are labeled INPUT 0, INPUT 1, and
INPUT 2, from top to bottom. Each input consists of –48 VDC and return—each with
its own 80-A circuit breaker. The input mode switch on the faceplate allows you to set the DC power supply to either two-input or three-input mode mode. Three-input mode is required for the T1600 routing node. Two-input mode is not currently supported.

Three-Input 240-A Power Supply Load Sharing and Fault Tolerance
When the routing node is operating normally and both power supplies are switched on, load sharing between them occurs automatically. When one power supply fails or is turned off, the other power supply immediately assumes the entire electrical load for the system. A single power supply can provide full power for as long as the routing node is operational. Table 2 on page 7 describes the behavior of the power supply if one of the inputs fails.
Table 2: Fault Tolerance
Two-Input ModeThree-Input ModeInput
INPUT 0
INPUT 1
If this input fails, INPUT 0, INPUT 1, and INPUT 2 shut down. The power supply shuts down, and the other power supply assumes the electrical load for all three inputs.
If this input fails, INPUT 0 is unaffected and INPUT 1 and INPUT 2 shut down. The other power supply assumes the electrical load of INPUT 1 and INPUT 2.
If this input fails, INPUT 0 and INPUT 1 shut down. The power supply shuts down, and the other power supply assumes the electrical load of INPUT 0 and INPUT 1.
If this input fails, INPUT 0 is unaffected and INPUT 1 shuts down. The other power supply assumes the electrical load of INPUT 1.
INPUT 2
If this input fails, INPUT 0 is unaffected and INPUT 1 and INPUT 2 shut down. The other power supply assumes the electrical load of INPUT 1 and INPUT 2.
Not applicable
Three-Input 240-A Power Supply LEDs
LEDs on each power supply faceplate (see Figure 4 on page 8) indicate the status of the power supply. In addition, a power supply failure triggers the red alarm LED on the craft interface. Table 3 on page 8 describes the functions of the power supply LEDs.

Preparing the Site

The following sections describe how to prepare your site so that you can install upgrade components.
■ Typical Power Distribution on page 12
■ Provisioning Additional Power for the T1600 Routing Node on page 13

Typical Power Distribution

The DC power supply in slot PEM0 must be powered by a dedicated power feed derived from feed A, and the DC power supply in slot PEM1 must be powered by a dedicated power feed derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system.
Figure 6 on page 13 shows a typical DC source cabling arrangement.
12 ■ Preparing the Site

Replacing the Rear Fan Tray

Figure 6: Typical DC Source Cabling to the T1600 Routing Node

Provisioning Additional Power for the T1600 Routing Node

For a maximally configured T1600 routing node, we recommend that you provision at least 64 A @ –48 VDC for each power supply input in the system.
We recommend that you provision a facility circuit breaker for each DC power supply input rated for at least 125% of the continuous current that the input draws at –48 VDC.
Replacing the Rear Fan Tray
NOTE: If the rear fan tray (model number FAN-REAR-TX-T640-S) is already installed, replacing the rear fan tray is not necessary. Proceed to “Upgrading the DC Power Supplies” on page 17.
The rear fan tray is hot-insertable and hot-removable. To replace a fan tray, use the following procedures:

26 ■ Upgrading the DC Power Supplies

Upgrading SIBs

NOTE: After a power supply is powered on, it can take up to 60 seconds for status indicators—such as the LEDs on the power supply, the show chassis command display, and messages on the LED display on the craft interface—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.
5.
Verify that the CB ON LEDs on the power supply faceplate are lit steadily. The
CB ON LEDs blink momentarily, then light steadily to indicate that the circuit
breakers are on.
6.
Verify that the DC OK LED on the power supply faceplate is lit steadily, indicating that the power supply is correctly installed and is functioning properly.
NOTE: After powering on a power supply, wait at least 60 seconds before turning it off. If the system is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the system again, first issue the CLI request system halt command.
Upgrading SIBs
After powering off a power supply, wait at least 60 seconds before turning it back on.
To convert an operational T640 routing node to a T1600 routing node, you upgrade the standard SIBs or SIBs version B in the T640 routing node to T1600-SIBs. You repeat the upgrade procedures for each of the five SIBs in the routing node.
NOTE: During the SIB upgrade:
■ The routing node should not experience packet loss if the traffic is less than
50 percent per Packet Forwarding Engine in each FPC.
■ The routing node might experience some packet loss if the traffic is more than
50 percent per Packet Forwarding Engine in each FPC, depending on the operational environment.
For more information, contact your customer support representative.

T1600 Routing Node DC Power Specifications ■ 45
T1600 Routing Node Upgrade Guide
NOTE: If you plan to operate a maximally configured T1600 routing node, we recommend that you provision at least 64 A @ –48 VDC for each power supply input in the system. Although Input 0 requires less power, we recommend provisioning the same amount of power for each input to avoid the possibility of connecting the lower-powered DC cable to Input 1 or Input 2.
Use a facility circuit breaker rated for 80 A (–48 VDC) minimum for each power supply input. Doing so enables you to operate the T1600 routing node in any configuration without upgrading the power infrastructure. You must provision a circuit breaker for each DC power supply input rated for at least 125% of the continuous current that the system draws at –48 VDC.

DC Power Cable Specifications

Table 8 on page 46 summarizes the specifications for the DC power cables, which you supply. For two of the inputs on each power supply, use the DC power cables and lugs that were connected to the two-input 160-A power supply. Four additional DC power cables are required. The accessory box shipped with the T1600 upgrade kit includes four cable lugs that attach to the terminal studs of the additional third input on each three-input 240-A power supply (see Figure 25 on page 46).

Preventing Electrostatic Discharge Damage

Many T1600 routing node hardware components are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets. Observe the following guidelines to minimize the potential for electrostatic discharge (ESD) damage, which can cause intermittent or complete component failures:
■ Always use an ESD wrist strap or ankle strap, and verify that it is in direct contact
with your skin.
CAUTION: For safety, periodically check the resistance value of the ESD strap. The measurement should be in the range of 1 to 10 Mohms.
■ When handling any component that is removed from the chassis, verify that the
equipment end of your ESD strap is attached to one of the ESD points on the chassis, which are shown in Figure 1 on page 4 and Figure 2 on page 5.
Preventing Electrostatic Discharge Damage
■ Avoid contact between the component and your clothing. ESD voltages emitted
from clothing can still damage components.
■ When removing or installing a component, always place it component-side up
on an antistatic surface, in an antistatic card rack, or in an electrostatic bag (see Figure 26 on page 47). If you are returning a component, place it in an electrostatic bag before packing it.
