Gathering Hardware Inventory Information

2017-11-03 09:05:07

Problem

You are taking a hardware inventory to track which hardware components are installed in which router, along with serial numbers.

Solution

The following command lists all the hardware components installed in the router:

aviva@router1> show chassis hardware Hardware inventory: Item Version Part number Serial number Description Chassis 25688 M20 Backplane REV 03 710-002334 BB9683 M20 Backplane Power Supply A REV 06 740-001465 005169 AC Power Supply Display REV 04 710-001519 BA4667 M20 FPM Board Routing Engine 0 REV 06 740-003239 9000016755 RE-2.0 Routing Engine 1 REV 06 740-003239 9001018324 RE-2.0 SSB slot 0 REV 02 710-001951 AZ8025 Internet Processor IIv1 SSB slot 1 N/A N/A N/A Backup FPC 0 REV 03 710-003308 BB5185 E-FPC PIC 0 REV 08 750-002303 BB5887 4x F/E, 100 BASE-TX PIC 1 REV 07 750-004745 BC9318 2x CT3-NxDS0 PIC 2 FPC 1 REV 03 710-003308 BF7478 E-FPC PIC 0 REV 03 750-002914 BC0119 2x OC-3 ATM, MM

Discussion

When you need to find out what hardware is installed in the router, use the show chassis hardware command. The first column of the output lists each hardware component installed in the router, starting with the chassis, which is the router itself. This router, an M20 system, has one power supply, two Routing Engines, one switching board (the SSB), and two FPCs with a total of four PICs. PICs are the network interface cards in the router. All these items are field-replaceable units (FRUs), so you or a service technician can replace them in the field.

The next three columns list the revision number, the Juniper Networks manufacturing part number, and the serial number. This information is very useful if you are tracking what router hardware you have and if you need to replace or return a defective piece of hardware.

The last column has a brief description of each hardware component. This is especially useful for finding out which PICs are installed on which FPC and in which location on the FPC. You need this information when you are configuring the router's interfaces because you must specify the FPC number and the PIC location to identify the interface (see Chapter 7). Most M-series and T-series routers have either four or eight slots for FPCs, and each FPC typically has four locations for PICs. The FPCs are numbered 0 through 7 (or 0 through 3), and the PICs are numbered 0 through 3. The numbering is always indicated on the router chassis itself, but if your routers are in a secured room, you likely don't have physical access to them.

The J-series router is a smaller router and has fewer hardware components:

aviva@RouterA> show chassis hardware Hardware inventory: Item Version Part number Serial number Description Chassis JN002648AA J2300 Routing Engine REV 07 750-009992 AA04451163 RE-J.1 FPC 0 REV 04 750-010739 AC04430335 FPC PIC 0 2x FE, 2x Serial

You can also get information about the memory storage areas on the router:
