OL-23875-02

You can speed up time-to-market by using the Cisco 5940 ESR, along with its associated Rear Transition Module (RTM), in industry standard enclosures. This deployment scenario is typically used for development systems or applications with less severe size, weight and power (SWaP) requirements. The RTM may be eliminated for production systems to save space, reduce cost and incorporate appropriate connectors. The Cisco 5940 ESR is based on industry standards – providing Cisco’s customers with an extensive combination of products and suppliers for designing and developing systems.

Cisco 5940 Embedded Services Router Hardware Technical Reference Guide Cisco 5940 Rear Transition Module (RTM) Card


OL-23875-02

Cisco 5940 Rear Transition Module (RTM) Card The Cisco 5940 Rear Transition Module (RTM) card takes the input and output data from the J2 connector on a midplane and provides four gigabit Ethernet interfaces and one console port on the RTM faceplate (see Figure 8 for an example). The RTM faceplate ports are standard RJ45 connectors and do not require special wiring.

The RTM can be used with either the air-cooled or conduction-cooled cards, but is most frequently used with the air-cooled card. If you do not use the RTM with the conduction-cooled card, you must ensure that you wire correctly from the J2 connector to your chassis connectors. See Table 7 for J2 pin-out assignments.

Figure 7 shows the Cisco 5940 RTM.

OL-23875-02

Removing the Cisco 5940 RTM Card

Warning To prevent electrostatic damage to cards in the rugged enclosure, attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis of the enclosure before you start the card replacement process.

To remove the Cisco 5940 RTM, perform the following procedure:

Step 1 Loosen the screws using a Phillips head screwdriver.

Step 2 Press the red button on the ejector lever on the module to disengage the lock.

Step 3 Carefully remove the Cisco 5940 RTM from the chassis.

Using the Cisco 5940 ESRYou can deploy the Cisco 5940 in a variety of applications and physical formats.

You can use a larger standard chassis, the Cisco 5940 card and Cisco 5940 RTM (Figure 9). In this configuration you connect both the Cisco 5940 ESR and RTM to a standard midplane using the J2 connectors on each board. The RTM provides the gigabit Ethernet interfaces and console ports that can connect to the other modules in the chassis or network.

You can also deploy the Cisco 5940 ESR into a custom chassis without using the Cisco 5940 RTM (Figure 10). This solution requires that the J2 connector signals be directly wired to the custom backplane. Any card to card connections are made by the backplane wiring. This solution has the advantage that you can design your custom chassis much smaller than most standard chassis that are available. The portions of the backplane not associated with the J2 I/O signals should still be designed in accordance with the cPCI specification.

Figure 10 Cisco 5940 ESR in Custom Chassis

A third possible solution can be the most compact and has the lowest power and weight. You can create custom connector wiring assemblies to wire the J1 and J2 connector signals on the Cisco 5940 ESR to chassis connector(s) (Figure 11). To use this method, the SYSEN# signal (J2.C2) and the BD_SEL# signal (J1.D15) need to be connected to GND. This makes the custom connector assembly emulate the system slot of a normal cPCI backplane to the Cisco 5940 ESR card.
