T1600 Routing Node Overview 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 s

T1600 Routing Node Upgrade Guide 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. ■ 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 enviro

Verifying the Hardware Version of the Rear Fan Tray 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. To verify that FAN-REAR-TX-T640-S is installed: 1. Issue the show chassis environment command: In this example, the outpu

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:

T1600 Routing Node Upgrade Guide 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. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. See “Preventing Electrostatic Discharge Damage” on page 4

Upgrading the DC Power Supplies 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. The power supplies are located at the lower rear of the chassis. Each power supply is hot-insertable and hot-removable. When one power supply is powered down or removed, the other powe

Upgrading the DC Power Supplies CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply. 5. Using a 7/16-in. nut driver or pliers, remove the nuts and washers
