Mounting accessories

Before installing the switch to the rack, install slide rails to the rack. You can order an HP X421 A-Series
Chassis Universal 4-Post Rack Mounting Kit (JC665A).
An HP X421 A-Series Chassis Universal 4-Post Rack Mounting Kit (JC665A) includes cage nuts, screws,
and a pair of slide rails. The length of the slide rails is in the range of 500 mm (19.69 in) to 800 mm
(31.50 in), and a pair of slide rails can bear up to 350 kg (771.60 lb) of weight. Before using the slide
rail, make sure:
The inside depth of the rack falls into the length range of the slide rail.
•
• The slide rails can support the total weight of the switch chassis and its accessories.

DC cables

If you use an A-RPS800 as the external PoE power supply, order an HP X290 14-pin Mini-Fit to 2 x OT
Copper Lug 1m RPS Power Cable (JG332A). At one end of the cable is an H2*7 plug, and at the other
end of the cable are two OT terminals with a minus (–) sign on the blue wire and a plus (+) sign on the
black wire.
If a 1400W DC power supply is used and the total power consumption of the switch (the system power
consumption plus the PoE power consumption) is greater than 3300 W, order HP X210 JG2 to T50 3m
DC (2) Power Cables (JG333A). The cable kit includes two cables, each having a minus (–) sign on the
blue wire and a plus (+) sign on the black wire.

PoE DIMM

You must install a PoE dual-in-line memory (DIMM) module on a PoE-capable LPU (except the
LSQ1GV48SD0 and LSQ3GV48SC0) to supply power over Ethernet.
Use Table 49
DIMM module is used, the Ethernet ports on the LPU work as common Ethernet ports and do not supply
power to powered devices (PDs).
