Cisco 5915 ESR Air-Cooled Card
To install the Cisco 5915 ESR conduction-cooled card, perform the following procedure:
Step 1
Carefully align the edges of the thermal plate between the upper and lower edges of the module slot.
Step 2
Verify that all the wedge locks are loose just enough to hold all the wedge lock pieces together.
Step 3
Slide the card into the module slot.
Step 4
Tighten the wedge locks using a hex torque screwdriver adjusted to 8.0 +/- 0.5 in-lb.
Removing the Cisco 5915 ESR Conduction-Cooled Card
Warning
When performing the following procedures, wear a grounding wrist strap to avoid ESD damage
to the Cisco 5915 ESR conduction-cooled card. Some platforms have an ESD connector for
attaching the wrist strap. Do not directly touch the edge finger or PCI connector pins with your
hand or any metal tool to avoid component failure.
To remove the Cisco 5915 ESR conduction-cooled card, use the following steps:
Step 1
Loosen the wedge locks using a hex screwdriver and complete seven (7) counter-clockwise turns.
Caution
Do not loosen the wedge locks past seven (7) counter-clockwise turns for removal. Doing so could cause
the wedge lock to fall off the card into the chassis.
Step 2
Carefully remove the Cisco 5915 ESR conduction-cooled card out of the conduction-cooled chassis.
Cisco 5915 ESR Air-Cooled Card
The Cisco 5915 ESR air-cooled card operates at a temperature range of -40ºC to +70ºC. Forced air is
used to cool the card.
Note
Cisco 5915 ESR air-cooled card installation depends on the system in which it will be used, hence the
installation information does not fall under the scope of this document.
The Cisco 5915 ESR air-cooled board (
Figure 5
and
Figure 6
) is used without thermal plates in an
air-cooled environment. The minimum air-flow required depends on the installation environment.
System integrators must perform the necessary thermal simulation to calculate the system level air-flow
requirement.
