switch fabric modules (half-height modules for the switch 8108fl;
1 full-height modules for the switch 8116fl) are installed in the central slots labeled fm. install the primary module in slot fm-a; install the hot standby module into slot fm-b. (when you install a single switch fabric module, you can use either slot fm-a or fm-b.)
2 management modules (thicker, half-height modules) are installed in slots labeled mm.
(1)if you are installing only one management module, you can install it in either slot mm-a or mm-b.
(2)if you are installing two management modules, the primary management module is the one installed in slot mm-a. the redundant management module is the module installed in slot mm-b.
3 interface modules (narrow half-height modules) are installed in numbered slots (1-8 on the switch 8108fl; 1-16 on the switch 8116fl).
be sure to install each type of module in its appropriate slot by referring to the slot number or label, as shown in the following illustration:
to avoid damaging modules and the backplane, be sure to insert the right type of module into the slot type designed for it. if you install a module in the wrong slot, physical keying prevents the module from fully entering the slot.
1 avoid damage from static electricity. static electricity can severely damage the electronic components on the modules. follow these procedures to avoid such damage:
(1)use proper esd grounding procedures before handling modules.
(2)handle the module by its bulkhead or edges and avoid touching the components and the circuitry on the board.
(3)when installing the module, equalize any static charge difference between your body and the switch by wearing a grounding wrist strap and attaching it to the switch’s metal body, or by frequently touching the switch’s metal body.
2 ensure you fully insert the modules. that is, press the module into the slot until the bulkhead on the module is contacting or is very close to contacting the front face of the switch chassis.
(1)do not force a module into its slot. if the module does not seem to be seating correctly, ease it back out and check alignment. forcing a module can damage it and the backplane. modules are keyed so that they cannot be fully installed in a wrong slot.
(2)check for alignment. make sure that the metal plate of the module —not the circuit board—is between the module guides. check both the upper and lower guides for proper alignment.
3 secure the module. once the module is fully inserted, make sure that you fully close the ejector levers and screw in the two retaining screws to secure the module in place.
4 for safe operation, proper switch cooling, and reduction of electromagnetic emissions, ensure that a slot cover is installed on any unused module slot. for safety, no more than one slot should be uncovered at a time when you install a module and while the switch is powered on.
hot swapping modules
modules can be “hot swapped”, that is installed or replaced while the switch is powered on. the procedures and conditions differ slightly, according to the type of module. for more information, see “hot swapping and redundancy”
installing a switch fabric module
a procurve switch 8100fl requires at least one switch fabric module to process traffic for any interface module. only one switch fabric module is required for full throughput.
note that the 8-slot switch 8108fl uses the half-height switch fabric module. the 16-slot switch 8116fl uses a full-height switch fabric module.
if you are installing two switch fabric modules, the primary switch fabric module is the one installed in slot fm-a. the redundant switch fabric module is the module installed in slot fm-b.
to prevent equipment damage, review the installation precautions.
to install a switch fabric module (j8729a or j8730a):
1. if a cover plate is installed in the switch fabric module slot, remove it by loosening the captive screws (using slotted or p2 phillips screwdriver) and pulling the ejectors.
2. open the ejectors at the top and bottom of the module, and hold the upper ejector lever in the unlocked position while you are installing the module (see step 1 in the illustration opposite).
3. position the switch fabric module in the fm-a slot (for primary module) or fm-b slot (for redundant module). (you can use either slot in a single switch fabric module installation.)
4. slide the switch fabric module all the way into the slot, firmly but gently pressing to make sure that the pins on the back of the module are completely seated in the backplane.
the 8116fl switch fabric module is a double height module, which makes it heavier than the other modules. make sure that the module is properly seated when you insert it in the switch chassis.
make sure that the metal plate of the module, and not the circuit board,is between the guides. check both the upper and lower guides for proper alignment.
do not force a module into its slot. if the module does not seem to be seating correctly, ease it back out and check alignment. forcing a module can damage it and the chassis.
5. to lock the module into the slot, close the ejectors until they are vertical.
6. tighten the captive screw on each ejector by hand and seat with a screw driver to keep the module from being removed accidentally. do not overtighten the captive screws.
the module must be fully seated and the ejectors fully locked (vertical) before the captive screws will align properly. also, fully seating the module ensures proper contact of the card with the backplane which is necessary for optimal performance.
7. repeat steps 1 to 6 to install a second switch fabric module to provide full (100%) redundancy in the event of a failure of the primary module.
installing a management module
the management module is the main processing unit of a procurve switch 8100fl and is required for the unit to operate. it contains system-wide bridging and routing tables, and runs the main control protocols.
in addition to a slot for the primary management module, the chassis also has a slot for a second (optional) redundant management module:
(1)if you are installing only one management module, you can install it in either slot mm-a or mm-b.
(2)if you are installing two management modules, the primary management module is the one installed in slot mm-a. the redundant management module is the module installed in slot mm-b.
to prevent equipment damage, be sure to follow the installation precautions
to install a management module (j8731a):
1. if a cover plate is installed in the management module slot mm-a or mm-b, remove the cover plate: loosen the captive screws on the ejectors until the screws pop out, then open the ejectors and pull out the plate.
2. open the ejectors at the top and bottom of the module, and hold the upper ejector lever in the unlocked position while you are installing the module (see step 1 in the illustration opposite).
3. align the metal plate of the management module with the guides at the top and the bottom of the slot opening, as shown in the illustration on the next page.
make sure that the metal plate of the management module, and not the circuit board, is between the module guides. check both the upper and lower guides.
do not force a module into its slot. if the module does not seem to be seating correctly, ease it back out and check alignment. forcing a module can damage it and the chassis.
4. slide the management module all the way into the slot, firmly but gently pressing to make sure that the pins on the back of the management module are completely seated in the backplane.
5. to lock the module into the slot, close the ejectors until they are vertical.
6. tighten the captive screw on each ejector by hand and seat with a screw driver to keep the module from being removed accidentally. do not overtighten the captive screws. (you can tighten the thumb screws with a p2 phillips screwdriver to eliminate the possibility of casual removal by unauthorized personnel.)
the management module must be fully seated and the ejectors fully locked (vertical) before the captive screws will align properly. also, fully seating the card ensures proper contact of the card with the backplane which is necessary for optimal performance.
7. repeat steps 1 to 6 to install a secondary management module to provide full (100%) redundancy in the event of a failure of the primary module.
installing an interface module
procurve 8100fl switches provide non-blocking throughput regardless of the software features you are using. therefore, you do not need to “load balance” interface modules by placing them in certain physical relationships to balance the load on the backplane. regardless of where you install the interface modules, the backplane can provide full, non-blocking throughput.
you can install interface modules in any numbered slot (1–8 on the switch 8108fl and 1–16 on the switch 8116fl). the illustration shows an example of how to install an interface module.
to install an interface module (j8733a, j8734a, or j8735a):
to prevent equipment damage, review the installation precautions.
1. if a cover plate is installed in the interface module slot, remove the cover plate: loosen the screws on the ejectors, then open the ejectors and pull out the plate.
2. open the ejectors at the top and bottom of the module, and hold the upper ejector lever in the unlocked position while you are installing the module (see step 1 in the illustration opposite).
3. align the metal plate of the interface module between the module guides, as shown in the illustration.
make sure that the metal plate of the interface module, and not the circuit board, is between the module guides. check both the upper and lower guides.
do not force a module into its slot. if the module does not seem to be seating correctly, ease it back out and check alignment. forcing a module can damage it and the chassis.
4. slide the interface module all the way into the slot, firmly but gently pressing the interface module in place to make sure that the pins on the back of the interface module are completely seated in the backplane.
5. to lock the module into the slot, close the ejectors until they are vertical.
6. tighten the captive screw on each ejector by hand and seat with a screw driver to keep the module from being removed accidentally. do not overtighten the captive screws. (you can tighten the thumb screws with a p2 phillips screwdriver to eliminate the possibility of casual removal by unauthorized personnel.)
the interface module must be fully seated and the ejectors fully locked (vertical) before the captive screws will align properly. also, fully seating the card ensures proper contact of the module with the backplane which is necessary for optimal performance.
7. repeat steps 1 to 6 to install any additional interface modules.
