Replacing a JCS1200 Fan Shuttle
Removing a JCS1200 Fan Shuttle
Figure 1 shows how to remove and install a fan shuttle.
Figure 1: Removing and Installing a JCS1200 Fan Shuttle
To remove the fan shuttle (see Figure 1):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Power off any Routing Engines in the JCS1200 platform (see Powering Off a JCS1200 Routing Engine).
- If the platform is connected to a power source, disconnect the power from the platform and remove the power cables.
- Disconnect the cables from the modules in the rear of platform.
- Remove any of the following modules that are installed
in the rear of the platform:
- Fan modules (see Removing a JCS1200 Fan Module).
- Network clock fillers (see Removing a JCS1200 Network Clock Filler).
- MUX cards (see Removing a JCS1200 MUX Card).
- Alarm panel module (see Removing a JCS1200 Alarm Panel Module or Module Filler).
- Loosen the four captive thumb screws on the fan shuttle.
- Loosen the captive thumbscrews on the release handles,
and pull the handles to the open position. The fan shuttle moves out
of the chassis approximately 0.5 in. (1.3 cm).
Caution: Use your hands to hold the frame of the fan shuttle where the fan module bays are located. Do not use the release handles to hold the fan shuttle.
- While you support the fan shuttle with your hands, pull the fan shuttle out of the JCS1200 chassis.
Installing a JCS1200 Fan Shuttle
Figure 2 shows how to remove and install a fan shuttle.
Figure 2: Removing and Installing a JCS1200 Fan Shuttle
To install the shuttle (see Figure 2):
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
- Make sure that no modules are installed
in the fan shuttle and that the release handles on the shuttle are
in the open position.
Caution: Use your hands to hold the frame of the fan shuttle where the fan module bays are located. Do not use the release handles to hold the fan shuttle.
- Orient the fan shuttle so that fan module bays 1 and 3 are above fan module bays 2 and 4.
- Align the shuttle with the chassis, and push the shuttle into the chassis until it stops.
- Push the release handles to the closed position. The shuttle moves back fully into the chassis.
- Tighten the four captive thumbscrews on the fan shuttle.
- Tighten the captive thumbscrew on each release
handle.
Caution: The release handles have a safety switch that disables power output from the power boxes. If the release handles are not secured to the chassis with the thumbscrews, the platform will not power on.
- Install any of the following modules that you removed
from the rear of the platform:
- Fan modules (see Installing a JCS1200 Fan Module).
- Network clock fillers (see Installing a JCS1200 Network Clock Filler).
- MUX card (see Installing a JCS1200 MUX Card).
- Alarm panel module (see Installing a JCS1200 Alarm Panel Module or Module Filler).
- Reconnect any cables that you disconnected from the modules in the rear of the platform.
- Reconnect the power to the platform (see Connecting the JCS1200 AC Platform to AC Power or Connecting the JCS1200 DC Platform to DC Power).
- Restart any Routing Engines that were powered off in the platform.
