Installing a Gigabit-Backplane Physical Interface Module on the SRX Series Services Gateway
Before you begin:
Ensure that the services gateway is powered off.
Note This step is applicable only for the SRX550 Services Gateway as it does not support hot-swappable functionality for GPIMs. The SRX650 Services Gateway supports hot-swappable functionality for GPIMs.
Ensure that the GPIM is installed in the appropriate GPIM slot. For information about the appropriate GPIM slots, see SRX Series Services Gateway Gigabit-Backplane Physical Interface Modules Overview.
To maintain proper airflow through the services gateway, leave blank faceplates in place over slots that do not contain GPIMs. Do not remove a blank faceplate unless you are immediately installing a GPIM in the empty slot. For more information about removing a blank faceplate, see Removing a Blank Gigabit-Backplane Physical Interface Module Faceplate from the SRX Series Services Gateway.
Installing a GPIM on the SRX550 Services Gateway is similar to installing a GPIM on the SRX650 Services Gateway.
To install a GPIM:
- Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage to the SRX Series Services Gateway.
- Grasp the handles on each side of the GPIM faceplate,
and align the edges of the GPIM circuit board with the guide rails
at each side of the GPIM slot.
Note If you are installing a double-high, double-wide GPIM such as the 24-Port Ethernet XPIM, you must remove the center GPIM slot bracket.
- Slide the GPIM into the services gateway until it seats
firmly in the device. See Figure 1 for information.
Caution Slide the GPIM straight into the slot to avoid damaging the components on the GPIM.
Figure 1: Installing a Single-High, Single-Wide GPIM in an SRX650 Services Gateway - Using a Phillips (+) screwdriver, tighten the captive screws on each side of the GPIM faceplate.
- Insert the appropriate cables into the cable connectors on the GPIM.
- If necessary, arrange the cables to prevent them from
dislodging or developing stress points:
Secure the cable so that it is not supporting its own weight as it hangs to the floor.
Place excess cable out of the way in a neatly coiled loop.
Use fasteners to maintain the shape of the cable loops.
After the STATUS LED light turns green and glows steadily on, the GPIM is online and functioning normally. See Figure 2 and Table 1 for hot-swappable components and their descriptions.
