Replacing Storage Media for a Supervisor Module
Caution Do not use embedded event manager commands to override the shutdown that can occur when the
three-minute timer expires or else an overtemperature condition can occur.
The fan trays are located on the back side of the Cisco Nexus 7018 chassis as shown in Figure 1-12 on
page 1-20.
Warning When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the
fan blades completely stop before you remove the fan tray. Statement 258
To replace a Cisco Nexus 7018 fan tray (N7K-C7018-FAN=), follow these steps:
Step 1 Place an antistatic mat or antistatic foam where you can place two fan trays.
Choose a place that prevents damage to the fan trays while they are outside the chassis.
Step 2 Unpack and place the replacement fan tray on the antistatic mat or antistatic foam.
Step 3 Loosen the four captive screws on the fan tray that you are replacing by turning them counterclockwise
until they are free of the chassis.
Step 4 Grasp the fan tray handle with one hand and pull the fan tray part way out of its slot on the chassis.
If the fan tray power connector does not easily unseat from the backplane, rock it gently.
Step 5 Place a hand under the bottom side of the fan tray to support it and pull the fan tray out of the chassis.
Step 6 Place the fan tray on an antistatic pad or repack it in its original packing materials.
Step 7 Grasp the handle for the replacement fan tray in one hand and orient the fan tray so that the lettering on
the LED labels is upright and readable.
Step 8 Place one hand under the bottom side of the fan tray, lift the fan tray to the open fan tray slot, align the
fan tray with the top and bottom chassis guides for the slot, and push the fan tray into the chassis until
the power connector seats in the backplane and the captive screws are aligned to their holes in the
chassis.
Step 9 Tighten the captive screws to 8 in-lb (0.9 N·m).
Step 10 Make sure that the STATUS LED turns on and is green.
Replacing Storage Media for a Supervisor Module
You can replace a CompactFlash card in either flash memory reader on any Supervisor 1 module or a
USB drive in either USB port on any Supervisor 2 or Supervisor 2E module. The replacement media
must already be formatted for the reader or port, or you must reformat the media after installing it.
Note The LOG FLASH and EXPANSION FLASH readers (Supervisor 1) and the LOG FLASH and
SLOT0 ports (Supervisor 2 or 2E) require different formats for their cards.
