Replacing the Chassis
Moving Processor Modules from the Old Chassis to the New Chassis
At the interface processor end of the chassis, slots contain the processor modules. (See Figure 1.)
The RSP2 occupies RSP slot 6 or 7. The remaining eleven slots, which are numbered 0 through 5
(CyBus 0), beginning at the far left, and 8 through 12 (CyBus 1), support any combination of
interface processors.
The processor modules are all keyed with guides on the backplane to prevent them from being fully
inserted in the wrong slot. Empty interface processor slots contain an interface processor filler (an
empty carrier) to help keep dust out of the chassis, provide EMI shielding, and maintain proper air
flow through the chassis interior.
Processor modules slide into the processor slots and connect directly to the backplane. The
spring-loaded ejector levers (see Figure 7) help to ensure that the bus connector on the back of the
processor module is fully seated in the backplane or fully dislodged from it. Captive installation
screws at both ends of each processor module faceplate prevent the processor from pulling away
from the backplane and support the EMI integrity of the system. Failure to use the ejector levers and
captive installation screws could result in a partial backplane connection, which can hang the system.
To retain your existing configuration, move interface processors to the same slot positions in the new
chassis. The lithium battery backup on the RSP2 retains the system configuration in nonvolatile
random-access memory (NVRAM). Therefore, if you install interface processors in the same slot
positions in the new chassis that they occupied in the old chassis, the system and the individual
interfaces should come up in their previous configuration. If you install interface processors in
different slots in the new chassis, the system will recognize the interfaces, but will leave them in a
shutdown state until you reconfigure and enable them.
We recommend that you use the slot and port configuration worksheet in Table 1 before you
Note
remove interface processors from the old chassis. (Also refer to Figure 10.) This will ensure that you
install them in the correct slots in the new chassis based on the configuration stored in NVRAM on
the RSP2.
Although interface processors support OIR, you must wait at least 15 seconds after inserting an
interface processor before inserting the next one. To help avoid errors with the installation, leave the
power off until you have moved all components into the new chassis and have verified that all of
them are installed properly.
Move the interface processors first, one at a time, then move the RSP2 last. Before you remove an
interface processor from the existing chassis, remove the interface processor filler from the
corresponding slot in the new chassis. Then immediately install the interface processor in the new
chassis and secure it in the slot before removing the next interface processor filler or module. If you
leave the interface cables attached to the interface processors, route the cables through the
cable-management brackets immediately after you secure the interface processor in the slot to help
keep the other slots clear during the installation.
If there is sufficient slack in the interface cables, and if you can easily move the processor modules
between the chassis without straining the cables, leave the interface cables connected. If you must
disconnect the cables, label each cable with its slot and port number before you disconnect it. Do not
reconnect the interface cables until you have installed all of the components in the new chassis (it is
easier to install interface processors when the slots are not impeded by cables that drop from other
slots). Use the optional cable-management brackets to keep the interface cables untangled and away
from other interface processor slots and ports.
