Figure 2: Rear View of the T1600 Routing Node T1600 Upgrade Kit To upgrade a T640 routing node to a T1600 routing node, you install the following hardware components: ■ Two redundant, load-sharing, .
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).

T1600-SIBs Figure 5 on page 9 shows a T1600-SIB. Figure 5: T1600-SIB Each T1600-SIB consists of the following components: ■ Switch fabric ASICs. ■ High-speed links to each FPC. ■ SIB online/offline button, located on the SIB faceplate. ■ Three LEDs located on the SIB faceplate that display the status of the SIB.
T1600 Routing Node Upgrade Overview NOTE: The T640 routing node can be upgraded while the routing node is powered on and operational. 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.
Verifying the Hardware Version of the Rear Fan Tray The rear fan tray, model number FAN-REAR-TX-T640-S, has eight fans and is required to support the additional thermal power generation of the T1600 routing node. Model number RHTREARTRAY-T-S has five blowers and does not provide sufficient cooling for the T1600 routing node.

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.
Removing the Rear Fan Tray The rear fan tray is mounted vertically on the right side of the rear of the chassis. The rear fan tray (model number RHTREARTRAY-T-S) weighs about 12 lb (5.4 kg). To remove the rear fan tray, follow this procedure (see Figure 7 on page 15): 1.
Figure 7: Removing the Rear Fan Tray Installing a Rear Fan Tray The rear fan tray (model number FAN-REAR-TX-T640-S) weighs about 10 pounds (4.5 kg). To install a replacement rear fan tray, follow this procedure (see Figure 8 on page 16): 1.

Upgrading the DC Power Supplies NOTE: You must upgrade both power supplies. Follow these procedures for one power supply, then immediately upgrade the other power supply. Mixing a two-input 160-A power supply and a three-input 240-A power supply is supported only during the upgrade.
CAUTION: Do not substitute a metric nut driver or wrench. A tool that does not fit the nuts exactly can damage them. If a 7/16-in. tool is not available, use pliers or an adjustable wrench.
CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and ( – ) to indicate their polarity.
Figure 11: Rear of the Power Supply Showing Midplane Connectors 11. Grasp the handle on the power supply faceplate and pull firmly. Slide it halfway out of the chassis (see Figure 12 on page 21). CAUTION: Each two-input 160-A power supply weighs approximately 23 lb (10.
Figure 12: Removing a Power Supply Setting the Input Mode Switch on a Three-Input 240-A Power Supply NOTE: Do not set the input mode switch if the power supply is installed in the chassis. If the power supply is already installed, you must remove it before setting the input mode switch.

Figure 16: Three-Input 240-A Power Supply with the Optional Cable Restraint To replace the cable restraint on a three-input 240-A power supply, use the following procedures: ■ Removing the Standard .
Connecting a Three-Input 240-A Power Supply To connect a three-input 240-A power supply to the power sources, follow this procedure: 1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
11. Verify that the ground and power cabling are correct, that they are not touching or blocking access to other hardware components, and that they do not drape where people could trip on them. 12. Replace the clear plastic cover over the terminal studs on the faceplate.
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.

2. Peel the protective backing off the T1600 agency label. 3. Apply the T1600 agency label on top of the T640 agency label. Registering Your T1600 Upgrade You must register the T1600 upgrade with Juniper upon completion of the upgrade. To register your upgrade: 1.
T1600 Routing Node Environmental Specifications Table 5 on page 44 specifies the environmental specifications required for normal T1600 routing node operation.
Table 6: Power System Electrical Specifications Specification Item Operating range: – 40.0 to – 72 VDC NOTE: If the input voltage from the DC power source drops below – 37.5 to – 39.5 VDC, the routing platform automatically shuts down. During automatic shutdown, the circuit remains active.
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.
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.
