Hardware Replacement Procedures

It is possible to “hot-swap” one module for another of the same type; that is,

replace one module with another while the switch is still powered on, without

interrupting the operation of the rest of the switch ports. If the modules are

not the same type, the switch may have to be reconfigured. If you use the

shutdown command first, the switch will not have to be reset.

Caution A 5-second delay is mandatory between removing a module, and either re-

installing it, or replacing it with another.

To replace the faulty AllianceONE zl Module with a replacement one, use the

following procedure:

1. Unscrew the retaining screws enough to disconnect them from the

threaded holes in the switch.

2. Using the extractor handles pull the module out from the slot.

3. Remove the HDD from the faulty module and install it in the replacement

module. The procedure is essentially the same as described under

“Replacing the HDD” on page 6 except that you move the HDD from one

module to another.

4. Remove the CF from the faulty module and install it in the replacement

module. The procedure is essentially the same as described under

“Replacing the Compact Flash” on page 8 except that you move the CF

from one module to another.

5. If the module you are replacing is an SBM AllianceONE zl Module

product, you will also have to remove the PCIe cards from the faulty

module and install them in the replacement module. Important: Make

sure that you place the PCIe cards in the same slots in the replacement

module as they were located in the faulty module.

6. Install the replacement module into the switch slots where the faulty

module was previously located, as described in the previous procedures.

Caution For proper cooling and reduction of electromagnetic emissions, ensure that

a slot cover is installed on any unused slot. In an operational chassis, an

unused slot should be covered if it is not used for more than 2 minutes.

7. Now please refer to “Restoring Product Operation” on page 12 for the

next steps to restore full software operation of your AllianceONE zl

Module product. Look for the section that applies to your product, and

“After zl Module Replacement”.
