Installing FRUs
As a best practice, connect power cordsafter installing all required FRUs. To ensure good ventilation,
install filler panels on unused slots.
Long-time exposure to strong air flow might cause discomfort. To avoid this hazard, do not stand
close to the air outlet vents while the switch is operating. If you must be next to the switch on the air
outlet vent side for an extended period, avoid the air flow or take other protective measures.
TIP:
Keep the chassis and the component packages for future use.
Attaching an ESD wrist strap
An S12501X-AF switch does not have an ESD jack and no ESD wrist strap is provided with it.
Prepare an ESD wrist strap for the switch yourself and ground the strap reliably.
The other S12500X-AF switch models each are provided with an ESD wrist strap. To minimize ESD
damage to electronic components, wear the ESD wrist strap and make sure it is reliably grounded
before you install FRUs.
To attach an ESD wrist strap:
1. Make sure the switch is reliably grounded. For information about how to ground your switch,
see "Installing the switch."
2. Put on the wrist strap.
3. Tighten the wrist strap to make sure it makes good skin contact. Make sure the resistance
reading between your body and the ground is between 1 and 10 megohms.
4. As shown in Figure 1, insert the ESD wrist strap into the ESD jack on the chassis.

Installing MPUs
CAUTION:
•If you are not to install an MPU in an MPU slot, keep the filler panel in the slot.
•Before you install an MPU in the chassis, make sure the connectors on the MPU are not broken
or blocked.
•When you install an MPU, avoid damaging the connectors on the MPU.
•To prevent a filler panel from being drawn into the chassis when fan speed is high, use both
hands to grasp the filler panel by its two sides during filler panel installation and removal on an
operating switch.
An S12501X-AF switch does not require MPUs.
Unless otherwise stated, the term "MPU" in this document refers to MPUs and cloud SEUs.
For the compatibility between the switch and the MPUs, see "Appendix B FRUs and compatibility
matrixes."
You can install one MPU, or two MPUs for redundancy on the switch. If you are to install one MPU,
install it in either of the MPU slots.

Installing MPUs for the S12516X-AF, S12512X-AF, and
S12508X-AF switches
For the S12516X-AF, S12512X-AF, and S12508X-AF switches, the ejector levers of the MPUs and
the ejector lever seats on the MPU slots have pink marks. The MPU installation procedure is the
same for the S12516X-AF, S12512X-AF, and S12508X-AF switches. The following uses the
S12516X-AF switch as example.
To install an MPU:
1. As shown by callout 1 in Figure 2, remove the filler panel from the target MPU slot.
Keep the removed filler panel secure for future use.
2. As shown by callout 2 in Figure 2, orient the MPU with lettering on it upright. Hold the MPU by
the front panel with one hand and support the bottomwith the other. Push the MPU steadily into
the slot along the guide rails.
Keep the MPU parallel to the slot to avoid touching other components in the chassis.
3. As shown by callout 3 in Figure 2, pull the ejector levers of the MPU outward when most part of
the MPU is inserted in the slot.
4. Push the MPU until the brakes on its ejector levers touch the slot edges tightly.
5. As shown by callout 4 in Figure 2, Continue to push the MPU by its middle part on the front
panel until you cannot move it.
6. As shown by callout 5 in Figure 2, push the ejector levers inward until they come in close
contact with the front panel.
7. As shown by callout 6 in Figure 2, fasten the captive screws on the MPU.

Installing MPUs for the S12504X-AF switch
The S12504X-AF switch MPU marks and MPU slot edges are pink-marked.
To install an MPU for the S12504X-AF switch:
1. As shown by callout 1 in Figure 3, remove the filler panel from the target MPU slot.
Keep the removed filler panel secure for future use.
2. As shown by callout 2 in Figure 3, pivot up the handle of the MPU.
3. As shown by callout 3 in Figure 3, orientthe MPU lettering on it upright. Holding the MPU by the
front panel with one hand and supporting the bottom with the other, push the MPU steadily into
the slot along the guide rails.
Keep the MPU parallel to the slot to avoid touching other components in the chassis.
4. As shown by callout 4 in Figure 3, push the MPU until the handle breaks touch the slot edges
tightly.
5. As shown by callout 5 in Figure 3, continue to push the MPU handle until the MPU is secure in
position.
6. Fasten the captive screws on the MPU.

Installing MPUs for the S12502X-AF switch
The S12502X-AF switch MPU has pink marks.
To install an MPU for the S12502X-AF switch:
1. As shown by callout 1 in Figure 4, remove the filler panel from the target MPU slot.
Keep the removed filler panel secure for future use.
2. As shown by callout 2 in Figure 4, press the latch on the MPU to release the ejector lever. Fully
open the ejector lever.
3. As shown by callout 3 in Figure 4, orient the MPU withthe upside up. Hold the MPU by the front
panel with one hand and support the bottom with the other. Push the MPU steadily into the slot
along the guide rails until it has firm contact with the slot.
Keep the MPU parallel to the slot to avoid touching other components in the chassis.

Installing LPUs
CAUTION:
•Before you install an LPU on the switch, make sure the connectors on the LPU are not damaged
or blocked.
•To prevent a filler panel from being drawn into the chassis when fan speed is high, use both
hands to grasp the filler panel by its two sides during filler panel installation and removal on an
operating switch.

7
CAUTION:
To prevent card damage and ensure correct operation, LPUs can only be used with switching fabric
modules of the same type.
•Type T LPUs have a character Tin their card identifier (for example,LSXM1CGQ36TD1). Type T
switching fabric modules have a character string of SFT in their card identifier (for example,
LSXM1SFT16E1).
•Type H LPUs have a character of Hin their card identifier (for example, LSXM1CGQ36HB1).
Type H switching fabric modules have a character string of SFH in their card identifier (for
example, LSXM1SFH16C1).
•Type F LPUs have a character of Fin their card identifier (for example, LSXM1CGP12FX1). Type
F switching fabric modules have a character string of SFF in their card identifier (for example,
LSXM1SFF16C1).
For the compatibility between the switch and the LPUs (also called interface modules), see
"Appendix B FRUs and compatibility matrixes."
The S12501X-AF and S12502X-AF switches support only S12500X-AF Type H LPUs.
Installing S12500-X LPUs
The S12500X-AF switch supports only FX and FE series S12500-X LPUs. To install an S12500-X
LPU on the switch, first install an interface module adapter in the LPU slot.
CAUTION:
For heat dissipation of the switch, you must install an LPU in the slot where an interface module
adapter is installed. If you are not to install an LPU in the slot, remove the interface module adapte
r
and install a filler panel.
Installing an interface module adapter
1. Remove the filler panel from the target slot. See callout 1 in Figure 2.
Keep the removed filler panel secure for future use.
2. As shown in Figure 5, align the adapter rear with the LPU slot and push the adapter slowly
along the guide rails into the slot.
3. As shown by callout 2 in Figure 5, use the screws provided with the interface module adapter to
secure the adapter to the chassis.

(2) Fasten the screws to secure the interface module adapter to the chassis
Installing an S12500-X LPU
The S12500-X LPU edges and the ejector lever seats on the LPU slots have purple marks.
To install an S12500-X LPU:
1. As shown in Figure 6, loosen the captive screws that secure the LPU to the protection box, pull
the ejector levers of the LPU outward, and pull out the LPU from the protection box. .
2. Orient the LPU with the PCB facing up. Hold the LPU by the front panel with one hand and
support its bottom with the other. Slide the LPU steadily into the target slot along the guide rails.
See Figure 7.
Do not touch the components on the PCB.
Keep the LPU parallel to the slot to avoid touching other components in the chassis.
3. As shown by callout 2 in Figure 7, pull the ejector levers outward when most of the LPU is
inserted into the slot.
4. Push the LPU until the brakes on its ejector levers touch the slot edges tightly.
5. As shown by callout 3 in Figure 7, continue to push the LPU by its middle part on the front panel
until you cannot move it.
6. As shown by callout 4 in Figure 7, push the ejector levers inward until they come in close
contact with the panel.
7. As shown by callout 5 in Figure 7, fasten the captive screws to secure the LPU to the interface
module adapter.
