Installing A Redundant Power Supply - Foundry Networks ServerIron 4G-SSL User Manual

Foundry ServerIron Hardware Installation Guide
WARNING: Make sure that the power source circuits are properly grounded, then use the power cord supplied
with the device to connect it to the power source.
WARNING: If the installation requires a different power cord than the one supplied with the device, make sure
you use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your
country. The mark is your assurance that the power cord can be used safely with the device.

Installing a Redundant Power Supply

The FastIron Stackable device ships with one AC or DC power supply. You can install a second supply for
redundancy.
If you need to install a redundant power supply, it might be easier to install it before mounting the device, although
the power supplies are "hot swappable" and can be installed or removed after the device is mounted and powered
on.
Installing an AC Power Supply
WARNING: Before beginning the installation, see the precautions in "Power Precautions" on page 4-7.
To install an AC power supply, do the following:
1. If necessary, remove the power supply locking screw located in the center rear of the device (illustrated
below).
2. If the empty power supply bay has a cover plate, press inward on the two latches near the edges of the cover
plate to unlock the plate, then remove the plate.
3. Remove the power supply from its packaging.
4. With one hand, hold the bar on the front panel of the power supply. With the other hand, support the
underside of the power supply, and insert the power supply into the empty power supply slot. Press until the
supply is completely in the slot, so that the connectors on the back of the supply are fully engaged with the
pins on the power backplane.
CAUTION: Make sure you insert the power supply right-side up. It is possible to insert the supply upside
down, although the supply will not engage with the power backplane when upside down. The power supply is
right-side up when the power connector is on the left and the fan vent is on the right.
5. Press the two latches near the edges of the supply outward to lock the supply in place.
6. Connect the power cord to the power supply.
7. Connect the plug end of the power cord into an outlet.
Installing a DC Power Supply
Use the following procedures for DC power supplies in ServerIron 4G devices.
WARNING: Before beginning the installation, see the precautions in "Power Precautions" on page 4-7.
