Installing A Power Module; Installing Cards - Huawei S2700 Series Quick Start Manual

6 Installing a Power Module

The installation methods for different power modules are the same.
For information about the power module supported by your model, see Power Module in the Hardware
Description of your switch on the Huawei support website.
All the power modules are hot swappable (except the 870 W PoE power module).
When installing a power module, slowly push it into the slot. If you feel resistance or find the module inclined,
pull the module out and push it into the slot again. Do not push the module with force; otherwise, the
connectors on the module and backplane may be damaged.
If only one power module is installed, install a power module filler panel in the empty power module slot.
It is recommended that you install two power modules in a switch to enhance power reliability if the switch
supports double power modules.

7 Installing Cards

Before You Start
The installation methods for different pluggable cards are the same.
For information about the cards supported by your model, see Cards in the Hardware Description of your
switch on the Huawei support website.
Only switch models S5700-SI, S5710-LI, and S5700-EI do not support hot swappable cards.
Cards that do not support hot swappable cannot be installed when the switch is running. You must power off
the switch, install the cards, and then power on the switch to activate the cards.
To use a front 4xGE or 4x10GE optical interface card on the S5700-SI, S5710-LI and S5700-EI, you must also
install an extended rear card ES5D00ETPB00. Otherwise, only two ports instead of four ports on this optical
interface card are available.
When installing a card, slowly push it into the slot. If you feel resistance or find the card inclined, pull the card
out and push it into the slot again. Do not push the card with force; otherwise, the connectors on the card
and backplane may be damaged.
Install filler panels in vacant slots.
Installation Procedure
Step 1 Use a Phillips screwdriver to loosen the captive screw on the filler panel.
Step 2 Pull the filler panel out by the captive screw. Keep the filler panel for future use.
Step 3 Turn the ejector lever of the card 45 degrees outward. Push the card into the chassis with your thumbs
(below the captive screws), until the screw on the front panel is completely in the chassis. Front cards for
the S3700-HI, S5700-HI, and S5710-HI have no screws, but the installation method is the same.
Step 4 Rotate the ejector lever inward to lock the card after the screw is completely in the chassis.
Step 5 Use the Phillips screwdriver to fasten the captive screws.
