Upgrading the Routing Engines in the T1600 Router

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.
2. Follow the standard replacement procedure described in the T1600 Core Router Hardware Guide .

Upgrading the Junos OS on a T1600 Router

You must upgrade the router to Junos OS Release 9.6R2 or later for offline integration of the T1600 router.

To upgrade the software, you use CLI commands to copy a set of software images over the network to memory storage on the Routing Engine. The Junos OS set consists of several images provided in individual packages or as a bundle. You normally upgrade all packages simultaneously.

1. Upgrade the Junos OS running on the T1600 router.

   For information about installing and upgrading Junos OS, see the Routing Matrix with a TX Matrix Plus Router Feature Guide  and Junos OS Installation and Upgrade Guide .

2. After you are satisfied that the new packages are successfully installed and running, issue the request system snapshot command to back up the new software.

   For more information, see the Junos OS System Basics Configuration Guide .

Powering Off the T1600 Router

To power off the T1600 router:

1. On the external management device connected to the Routing Engine, issue the request system halt both-routing-engines operational mode command. The command shuts down both Routing Engines cleanly, so their state information is preserved. (If the router contains only one Routing Engine, issue the request system halt command.)
   user@host> request system halt both-routing-engines

   For more information about these commands, see the Junos OS System Basics and Services Command Reference .

2. Wait until a message appears on the console confirming that the operating system has halted.

   Halt the system ? [yes,no] (no) yes
   
   *** FINAL System shutdown message from user@host ***
   
   System going down IMMEDIATELY
   
   Terminated
   
   ...
   
   syncing disks... 11 8 done
   
   The operating system has halted.
   
   Please press any key to reboot.
   

3. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
4. Switch the circuit breakers on each power supply faceplate to the off position (O).

Replacing the T1600 Power Supplies

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.
2. Replace the power supplies as required for the converted T1600 router. Use the standard replacement procedures described in the T1600 Core Router Hardware Guide .

Upgrading the T1600 Rear Fan Tray

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.
2. Replace the rear fan tray with the model required for a converted T1600 router. Use the standard replacement procedure described in the T1600 Core Router Hardware Guide .

Setting the Chassis ID on the T1600 Router

You configure a T1600 chassis ID by setting a physical switch on each LCC-CB faceplate in the T1600 router (see LCC-CB on the T1600 Router). A chassis ID must be from 0 through 3. You must follow these requirements when setting the LCC-CB ID switches:

• Both LCC-CBs in a T1600 router must have the same switch setting.
• The switch setting for each T1600 router must be unique within the routing matrix.
• If the routing matrix contains only one T1600 router, we recommend that you assign a chassis ID of 0 to the router.
• The chassis IDs in a routing matrix do not need to be contiguous.
• The switch settings must match where the control cables are connected on the LCC-CB.
• Do not assign a chassis ID greater than 3.

1. Set the chassis ID switch on each LCC-CB to a value from 0 through 3. You must use the same chassis ID on each LCC-CB on the T1600 router.
2. Set the M/S switch on the LCC-CB on the T1600 router faceplate to M.

Upgrading the T-CBs in the T1600 Router with LCC-CBs

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.
2. Replace each CB with an LCC-CB on the T1600 router. Use the standard replacement procedure described in the T1600 Core Router Hardware Guide .

Upgrading the SIBs in the T1600 Router

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.
2. Replace each SIB with a TXP-T1600 SIB (Figure 2). Use the standard replacement procedure described in the T1600 Core Router Hardware Guide .

   Note: Ensure that the ejector handle tabs are properly mated inside their corresponding chassis slots before you tighten the captive screws on the ejector handles. You might have to close and open the handles a few times before the tabs catch the slots.
