F.2.3

Installing Fabric Module

You must make space for installing the module by removing an existing one (Removing Fabric Module)

or removing a blank (Removing Fabric Module Blank) from a fabric module slot available on the switch.

Perform the following steps to install the module.

1. Put on a grounded, anti-static ESD strap.

2. Unpack the module to be installed.

3. Open the ejector handles and carefully slide the module into the open slot.

4. Seat the module with the ejector handles open at 90 degrees.

5. Close the ejector handles.

6. Screw in the two Phillips screws.

7. Verify that the module is operating normally (Power Supply Status Indicators).

8. Use the show environment cooling command to further verify normal operation.

F.2.4

Removing Service Provider 7500N Series Fan and Safety Guard

ESD GROUNDING STRAP ADDITION

This product must be grounded. Never defeat the ground conductor or operate the equipment in the

absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority

or an electrician if you are uncertain that suitable grounding is available. When installing or replacing

this product, the ground connection must always be made first and disconnected last, and the person

performing the task(s) must wear a grounded, ESD (anti-static) strap.

On 7500 series products, you must replace the entire fabric module to replace a fan.

•

For the 7504 and 7508, unscrew the two Phillips screws on the back of the fabric module. Rotate

the ejector handle(s) 90 degrees back to hard stops and pull the fabric module straight back to

remove. Install the replacement fabric module by first opening the ejector handle(s), then aligning

the module in its slot with the same orientation as the original, and sliding it into the slot in the

same orientation as the one removed. When the module is seated, rotate the ejector handle(s)

forward and fasten the Phillips screws.Do not overtighten Phillips screws.

•

For the 7512 the failed fan replacement requires the removal of the plastic safety guard in addition

to the fabric module. First, in the CLI console, enter the global configuration mode by issuing the

commands enable, then config, followed by env fan-speed override 100 to increase fan speeds.

Wait five minutes for the system to sufficiently cool. Unscrew the six captive screws on the outside

perimeter of the plastic safety guard. Set the safety guard aside. Fabric module removal and

reinstallation procedure is the same as the 7504/7508 instructions above. Caution, the 7512R fabric

module weighs more than 25lbs. Support module during handling. Reinstall plastic safety guard

and fasten the six captive screws. Issue the env fan-speed auto command in the CLI console for

normal operation.

F.3

Touch Point Shield (Optional)

F.3.1

Installing the Touch Point Shield

The 7512N supports an optional Touch Point Shield component that is attached to the rear of the

device. Perform the following steps to install the Touch Point Shield to the 7512N.

1. Attach the ground cable to the chassis.

Note: The ground cable should be attached so that it exits upwards to enable access to the

ESD port on the chassis. You may arc the ground cable downwards, if needed (Figure 48:

Installing the Touch Point Shield (7512N)).
