Grounding the switch with a grounding conductor buried in the 
earth ground 
If the installation site has no grounding strips, but  earth ground is available, hammer a 0.5 m (1.64 ft) or 
longer angle iron or steel tube into the eart h ground to serve as a grounding conductor.  
The dimensions of the angle iron must be at le ast 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The steel 
tube must be zinc-coated and its wall thickness must be at least 3.5 mm (0.14 in).  
Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion 
protection.

Grounding the switch by using the AC power cord 
If the installation site has no grounding strips  or earth ground, you ground an AC-powered switch 
through the PE wire of the power cord. Make  sure the following requirements are met:  
•   The power cord has a PE terminal.  
•   The ground contact in the power outlet is securely  connected to the ground in the power distribution 
room or on the AC transformer side.  
•   The power cord is securely connected to the power outlet.  
 
  NOTE: 
If the ground contact in the power outlet is no t connected to the ground, report the problem and 
reconstruct the grounding system.

  NOTE: 
To guarantee the grounding effect, use the grounding  cable provided with the switch to connect to the 
grounding strip in the equipment room as long as possible. 
 
Installing/removing a power supply 
This section applies only to the A5500-24G-SFP EI  (2 slots) and A5500-24G-SFP EI TAA (2 slots) 
switches.  
This section uses a PSR150-A power  supply as an example to describe the installation and removal of 
power supplies. 
Installing a power supply 
  CAUTION: 
•
  To prevent damage to the power supply or the connector on the backplane of the powered device, 
insert the power supply gently. If you encounter a hard resistance while inserting the power supply, 
pull out the power supply and then insert it again.  
 
To install a power supply: 
1. Wear an ESD-preventive wrist strap and make sure  it makes good skin contact and is properly 
grounded.  
2.  If the power supply slot is covered by a fi ller panel, remove the filler panel first.  
Put away the filler panel for future use.  
3.  Unpack the power supply and check that the power supply model is correct.  
4. Correctly orient the power supply with the power su pply slot, grasp the handle of the power supply 
with one hand and support its bottom with the other, and slide the power supply slowly along the 
guide rails into the slot (see callout 1 in  Figure 16).  
T

he slot is foolproof. If you cannot insert the powe r supply into the slot, re-orient the power supply 
rather than use excessive force to push it in.  
						

							 20  
5.
 
Fasten the captive screws on the power supply wi th a Philips screwdriver to secure the power 
supply in the chassis (see callout 2 in  Figure 16). If the captive screw cannot be tightly fix
 ed, check 
the installation of the power supply. 
Figure 16  Installing a power supply 
 
  NOTE: 
If you install only one power supply, install the filler panel over the empty power supply slot for good 
ventilation.  
Removing a power supply 
To remove a power supply:  
1. Wear an ESD-preventive wrist strap and make sure  it makes good skin contact and is properly 
grounded.  
2.  Disconnect the power cord from the power supply and the power outlet. 
3. Loosen the captive screws of the power supply with  a Philips screwdriver until they are completely 
disengaged. 
4.  Grasp the handle of the power supply with one hand  and pull it out a little, support the bottom with 
the other hand, and pull the power supply slowly along the guide rails out of the slot.  
 
  NOTE: 
Put away the removed power supply in  an antistatic bag for future use.

Installing/removing an interface card 
 
 IMPORTANT: 
To set up an A5500 EI or A5500 SI
 IRF fabric, you must install interface cards. To choose a correct 
slot for an interface card, see “ Planning the cabling scheme.”  
 
This section applies to all A5500 EI and A5500 SI switches. For the interface cards available for the 
switches, see “Interface cards.” 
This 

section uses the LSPM2SP2P interface card as an  example to describe the procedures of installing 
and removing an interface card.  
						

							 25  
Installing an interface card 
To install an interface card in an interfac e card slot at the rear of the chassis:  
1. Wear an ESD-preventive wrist strap and make sure  it makes good skin contact and is properly 
grounded. 
2.  Loosen the mounting screws on the filler panel over the interface card slot with a Phillips 
screwdriver and remove the filler panel. Put aw ay the removed filler panel for future use.  
Figure 22  Removing the filler panel over an interface card slot 
 
 
3.  Hold the captive screws on the front panel of the  interface card, and gently push the interface card 
in along the slot guide rail until the interface card is in close contact with the switch chassis (see 
callout 1 in  Figure 23).
 
4. Tighten the captive screws with a Phillips screwdrive r to fix the interface card in the slot (see callout 
2 in  Figure 23 ). When you tighten the captive screws, the torque m
 ust not be higher than 0.4 N-m.
