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.
